  • Dragonfly narrowband IoT unveiled with GNSS option

    CEVA Inc., licensor of signal processing IP forconnected devices, and Hong Kong Applied Science and Technology Research Institute Company Limited (ASTRI) have introduced Dragonfly NB1, a comprehensive cost- and power-optimized NB-IoT solution aimed at streamlining the development of LTE IoT devices.

    Dragonfly NB1 leverages CEVA’s heritage of low-power DSPs and modem design and ASTRI’s experience in RF and IC Design technologies. Together, the companies have collaborated to produce a complete machine-to-machine (M2M) endpoint solution that offers best-in-class performance and power consumption, that is easily integrated into a system on chip (SoC).

    GMV Add-On for GNSS. CEVA and ASTRI have teamed up with GMV, a navigation system and solutions company, to offer an integrated GNSS solution for smart devices with location tracking of logistics, assets, wearables and more. The GNSS IP is available as an add-on software that runs on the CEVA-X1 together with NB-IoT and leverages ASTRI’s GNSS RF IP that is embedded into the solution.

    GMV’s software IP supports all four GNSS constellations: GPS, BeiDou, GLONASS and Galileo. The flexibility enabled by running the GNSS constellations fully in software on Dragonfly NB1 allows seamless switching between constellations when required or to run multiple constellations concurrently in order to improve resolution further and offer a truly global asset tracking solution.

    “Dragonfly NB1 with its multi-mode RF and dedicated IoT processor is a perfect match with GMV’s software GNSS product,” said Miguel Manuel Romay Merino, executive director of GNSS at GMV. “It provides full flexibility in using multiple constellations, either separately or concurrently to serve the various requirements specific to asset trackers, wearables and other IoT endpoint devices.”

    Dragonfly Features

    Dragonfly NB1 not only reduces the time taken to get NB-IoT products certified, but also provides low-power wide-area (LPWA) SoC designers with a flexible, software-upgradeable platform with key benefits in terms of die size and power consumption:

    • The Dragonfly NB1 solution is enabled by a single CEVA-X1 IoT processor, capable of running the complete PHY and protocol stack software for NB-IoT in addition to other associated workloads such as GNSS and sensing. It eliminates the need for additional processors and hardware accelerators in the SoC and allows in-the-field upgrades to Release 14 eNB-IoT and other future releases.
    • The CEVA-X1 IoT processor architecture includes specialized NB-IoT instructions and mechanisms to speed up PHY, MAC and encryption execution, further reducing clock speed and power consumption. It can also support other LPWA standards and workloads such as Cat-M1, LoRa, SigFox and voice.
    • The Dragonfly NB1 solution incorporates highly power-efficient multi-standard RF with embedded PA, LNA, DC-DC and DCXO technology for NB-IoT and GNSS (GPS and BeiDou), shortening development time and reducing the overall module bill of materials.

    Memory is a critical consideration for NB-IoT, as it directly influences the cost, silicon area and overall form factor of the module. Dragonfly NB1 is specifically designed to operate with embedded flash by incorporating an optimized low latency memory subsystem with a dedicated cache controller. The solution also includes a specialized security unit for a fully-trusted system.

    “In the coming years, NB-IoT will become the dominant technology for low power wide area connectivity. For most companies, understanding how to develop this technology is a daunting task,” said Michael Boukaya, Vice President and General Manager, Wireless Business Unit at CEVA. “To overcome this, we have worked relentlessly with ASTRI to develop a complete solution from the ground up, that removes the design burden and allows SoC designers to add NB-IoT connectivity to their product designs. We’re extremely excited to announce this solution and demonstrate our leadership in IP for NB-IoT.”

    “We’re pleased to partner with CEVA to address the cellular IoT market opportunity,” said Frank Tong, CEO at ASTRI. “Our joint development efforts have resulted in a highly-integrated modem solution with integrated RF that delivers outstanding performance and is power-optimized for the most rigorous NB-IoT use cases. We look forward to continuing our collaboration as we help our mutual customers get to market.”

    Reference silicon of the complete modem design — including embedded CMOS RF transceiver, advanced digital front-end, physical layer software and third-party protocol stack (MAC, RLC, PDCP, RRC and NAS) — will be available this June.

  • u-blox and Digicom partner on narrowband IoT products

    u-blox and Digicom partner on narrowband IoT products

    Chip-maker u-blox is parntering with Digicom, a company that offers a wide range of hardware and software with cellular connectivity, to develop narrowband IoT (NB-IoT) products and solutions. Both companies have carried out a series of innovative and successful field trials of the new NB-IoT technology.

    The announcement reflects u-blox’s and Digicom’s eagerness to meet pent-up demand for Low Power Wide Area (LPWA) connectivity, as delivered by NB-IoT technology, standardized by 3GPP in June 2016.

    The benefits of NB-IoT over other cellular radio technologies include lower device complexity, ultra‑low power operation and support for > 50 k devices per single cellular cell. As NB-IoT operates on networks within the licensed spectrum, it also offers greater security and freedom from interference.

    It is therefore suitable for IoT and M2M applications requiring extremely low power consumption and better coverage even in shielded areas.

    The collaboration is driven by a complementary business relationship between the two companies. Digicom offers innovative solutions for the industrial markets using NB-IoT, with a particular focus on connectivity solutions for Smart Cities, Smart Buildings, Industry 4.0 in general and the Automotive industry. Digicom platforms are designed for the protection of vehicles, people and pets, offer ultra low power consumption and several years operation in battery mode.

    Embedded in Digicom’s products and solutions is for instance the u-blox SARA‑N2 NB-IoT module, which was announced in June 2016 as a cellular radio module compliant with 3GPP Release 13. Release 13 defined the NB-IoT cellular air interface standard, specifically targeting devices that need to communicate small amounts of data over long periods of time in hard-to-reach places.

    “We have collaborated with u-blox for a long time and the quality and innovation of their modules enable us to develop cutting-edge products and solutions,” said Stefano Galzignato, business line manager at Digicom.

    “We are excited to be part of this partnership, which showcases u‑blox as a global leader in developing NB‑IoT solutions for IoT applications,” said Stefano Moioli, u‑blox director of product management, cellular.

    The partnership is expected to grow steadily alongside a rising demand for Digicom solutions for IoT markets.

  • GNSS plays prominent role at Mobile World Congress

    Global navigation satellite system (GNSS) technology found its way into products ranging from autonomous vehicles to wearables at this year’s Mobile World Congress in Barcelona, Spain.

    One company says it is tailoring a GNSS receiver chip to meet the demands of mobile devices that require high levels of speed and position accuracy. Thalwil, Switzerland-based u-blox said its new low-power UBX-M8230-CT GNSS receiver chip can not only be used for smartwatch development, but for tracking people, animals and assets.

    “The highlight of the chip is that it has much better balance, while maintaining the accuracy of a traditional, full-power receiver,” said Florian Bousquet, u-blox market development manager. “It can work in the most difficult urban canyon environments. It works well in sports watches, smartwatches, activity trackers and other wearables — and just about anything portable that has a battery.”

    Bousquet said the chip, in what the company calls a Super-E mode, uses GPS with either GLONASS or BeiDou. This mode allows batching location data on the chip, which reduces power consumption, he said.

    Bousquet said the chip is available now, in an evaluation kit, for around $120. He said the chip will be manufactured in volume this summer.

    It took u-blox a year-and-a-half to develop the GNSS chip, Bousquet said. “It took time for our development team to optimize the system and field test the infrastructure to make sure the product performed in different scenarios and environments.”

    Another company, Racelogic, exhibited its LabSat 3 Wideband GNSS simulator, which is used by u-blox and others to help test and develop products. Some applications include drones, autonomous vehicles, survey equipment, personal monitoring devices, aerospace and end-of-the-line product testing, the company said.

    The newer L2C, L5 and L1C signals give companies the opportunity to develop products that are compatible with new receivers as they come to market, said Mark Sampson, LabSat product/sales manager.

    The company also showed off its SatGen v3 simulator software that allows users to create a data file to be replayed on the LabSat GNSS simulator. The software allows companies to define a complicated route, and then import it into the software.

    Company tests eCall and ERA-GLONASS modules

    Both the European Union (EU) and Russian Federation are requiring governments to have intelligent telematics-based safety systems. In case of a serious accident, these systems automatically call for local medical services.

    Technology to meet the requirements of eCall and ERA-GLONASS include an antenna, GNSS receiver, crash sensors and other components.

    To reproduce end-to-end and standard-compliant testing of the eCall and ERA-GLONASS modules, Rohde & Schwarz offers two products. One is the CMW-KA094 eCall application software. The other is the CMW-KA095 extension for ERA-GLONASS to simulate a public safety answering point (PSAP) to emulate a cellular network in a lab.

    “It’s pretty important testing because of the safety of life. We have set up implementation of it in our labs,” said Christian Hof, Rohde & Schwarz senior product manager for mobile radio testers.

    During testing, governments and companies can use the CMW500 platform, which identifies Internet of Things (IoT) and mobile communications devices’ IP connection security issues, Hof said.

    The company believes, since many IoT platforms are proprietary as standardization is still in progress, security gaps are frequently reported.

    Spirent rolls out new simulator

    Spirent Communications displayed its Elevate IoT Device Test Solution, a new cellular test designed to support IoT applications. These applications include end-to-end cloud server connectivity, security-vulnerability assessment and battery-life measurement.

    The new unit is available through the company’s Spirent Elevate platform, which addresses areas affected when designing 3G, LTE and new narrowband wireless technologies for IoT devices.

    Overall, Spirent is finding many use cases and applications in the IoT and mobile industry.

    “We are finding that smaller companies developing software and services want to test GNSS, but don’t have the capabilities to do so. These could include small projects such as people and pet trackers,” said Simon Loe, Spirent’s head of marketing solutions and services. “We are trying to democratize the technology. Another trend we are seeing is growing importance on GNSS in network timing.”

    Not everything is about drab simulation. Far from it. Spirent last year teamed with Aston Martin Racing to evaluate automotive technologies on the 2016 V8 Vantage GTE race cars.

    This includes the accuracy and performance of GPS receivers and interference monitoring, said Julian Kemp, Spirent product manager, custom solutions.

    Antenna market for IoT, autonomous vehicles robust

    Taoglas is offering GNSS antennas that support IoT products, unmanned aerial vehicles (UAVs) and future autonomous vehicles, said Ronan Quinlan, company co-founder.

    The company is offering lightweight antennas for mass-market unmanned UAVs, which had a growing presence at Mobile World Congress this year.

    The future markets for Taoglas will be in connected and autonomous vehicles, Quinlan said. “We found out years ago that we missed out on the rise of 2G, but we did not miss the rise of 4G. The advent of 5G and GNSS will lead to the development of the autonomous vehicle,” he said.

    Antenna costs associated with the rise of autonomous vehicles will have to be reduced, Quinlan said. “Some antennas that were $100 solutions have to go down to $20 solutions once they get into a car,” he said.

    In other Mobile World Congress news:

    • Fraunhofer IIS displayed its Enhanced Voice Services (EVS), the Third Generation Partnership Project (3GPP) communication protocol designed specifically for voice over LTE (VoLTE) services.
    • Telit said it is expanding its relationship with Tele2 on Pan-European long-term evolution (LTE) IoT connectivity services. Telit and Tele2 now offer custom data plans with predictable pricing, no hidden fees or roaming charges for high bandwidth IoT applications, the company said. Services include video monitoring, digital signage or real-time asset tracking.

  • Spirent’s new wireless test solution optimized for IoT devices

    Spirent Communications is now offering the Elevate IoT Device Test Solution, a new cellular test solution designed to support a wide range of testing areas applicable to Internet of Things (IoT) applications, including end-to-end cloud server connectivity, security vulnerability assessment and battery-life measurement.

    The announcement was made at Mobile World Congress, which is taking place Feb. 27 to March 2 in Barcelona, Spain.

    The compact and flexible device test solution, available via the Spirent Elevate platform, addresses critical areas that are affected when designing 3G, LTE, and upcoming narrowband wireless technologies into IoT devices.

    Innovative IoT developers are emerging worldwide with many of their applications reliant on communicating via a cellular network. Cellular deployment has several benefits including higher guaranteed service quality, more robust air interface security, and broader coverage availability. Yet designing IoT devices can present a myriad of complex challenges, especially when cellular connectivity enters the equation.

    Testing on a live network has several limitations: data traffic is not visible between the device and cloud server; the appropriate live network may not be deployed where the development takes place; and there is no ability to control network settings such as power levels.

    Spirent Elevate provides easy access to a controllable, lab-based testing environment, allowing developers to explore the special challenges a cellular network presents in a repeatable manner.

    A number of recent events, including widespread Distributed Denial of Service (DDoS) attacks, has illustrated the very real exposure of IoT device security, highlighting the immediate need for developers to ensure devices are protected from known baseline vulnerabilities.

    The Elevate IoT test solution facilitates access to Spirent SecurityLabs services, including dedicated teams of experienced security professionals offering comprehensive scanning, penetration testing and monitoring services for embedded devices.

    Many IoT devices require operation in hard-to-reach places for extremely long periods of time while in potentially unforgiving environments, making it imperative that batteries perform as expected under variable conditions. The Elevate IoT Device Test Solution allows developers to accurately determine predictable battery life in real-world conditions with actual usage profiles.

    “The Internet of Things is here to stay — it represents a cultural and technology revolution, and has serious implications for security,” said Jeff Wilson, research director and advisor, cybersecurity technology, at analyst firm IHS. “The post-IoT threat landscape is complicated, and the consequences of attacks are increasingly severe. If a device is compromised, it can either fail to work itself, or introduce threats into a wider network, or both; the Mirai and LizardStresser IoT botnets used to launch DDoS attacks were just the tip of an enormous iceberg. Successfully managing connectivity, technology and risk will be vital to IoT implementations from this point forward.”

    Spirent’s IoT Device Test Solution is an integrated suite of tools centered in a compact network emulator that brings a repeatable cellular test bed into any hardware or software lab, providing the ability to replicate service providers’ wireless networks in a portable desktop system.

    When used as part of an expanded Spirent solution that can simulate multiple types and levels of security attacks, the system allows users to accurately understand how a device will hold up against each one and what factors may be impacted.

    Emulating as many conditions as possible helps developers understand exactly how devices, including factors such as battery life, may be impacted in the real world.

    “For IoT developers, many of them new to cellular technology, it can be dauntingly complex to navigate new technologies, manage power performance challenges, and care for imminent cybersecurity threats,” said Saul Einbinder, vice president of new venture development at Spirent Communications. “Our aspiration is to help developers, operators, and service providers optimize their IoT solutions and get to market faster, while also staying considerate of the budget constraints of IoT device realization.”

    Telit autonomous nav module uses internal sensors, GNSS

    Telit has announced the commercial availability of the SL869-3DR, a GNSS module for global use that leverages information from internal gyros, accelerometers and a barometric pressure sensor to perform dead-reckoning navigation for application areas such as track and trace and in-vehicle systems.

    The module delivers accurate position data either directly from its multi-constellation receiver or from a fully autonomous dead-reckoning system, requiring no connections to external devices or components other than an antenna for satellite signal reception and power.

    The module allows integrators to design zero-installation, in-vehicle navigation and tracking devices for fleets and other commercial or consumer applications that operate perched on the dashboard, connected only to vehicle power.

    Photo: TelitThe SL869-3DR is a flash-memory based module capable of tracking three constellations simultaneously. The module integrates an array of micro electromechanical systems (MEMS) designed to provide it seven degrees of freedom. The innovative design of the internal sensor array in conjunction with the Telit MEMS-only Dead Reckoning (MoDR) software and intellectual property, deliver the host device unparalleled portable, turnkey dead-reckoning performance.

    The Telit MoDR solution ensures that reliable position, velocity and time information is constantly available to the host application even when GNSS coverage is compromised, without the need for connection to the vehicle for wheel-ticks for speed or reverse-gear data. Its standard footprint lets navigation and tracking system integrators reuse existing device designs, eliminating complexity from external sensors and other apparatus, getting to market quickly with updated designs or product innovation.

    “A significant number of the millions of commercial vehicles and fleets on the roads today are still operating with no or unreliable navigation systems because installation costs to connect the device to vehicle sensors are too high and require very specialized skills,” said Felix Marchal, executive vice president of GNSS and Short Range Wireless. “With the SL869-3DR we overcome that barrier because it enables devices that you simply connect to vehicle power and go. Up until now, ‘power-and-go’ navigation systems have largely relied on open-sky visibility, which is not typically where most commercial fleets operate. They are moving through tunnels, urban canyons and other environments where these systems cannot produce a position solution. Reliable MEMS-only dead reckoning, or MoDR as we call it, relies on very complex mathematical modeling and expert design of the sensor array. Developers must therefore, thoroughly scrutinize performance of the different products in the market. I am delighted that the SL869-3DR has outperformed competing products in its class across a wide range of test cases.”

    The SL869-3DR is designed to support GPS, QZSS, GLONASS, Beidou and is Galileo ready. Telit MoDR technology boosts position accuracy in areas with adverse satellite reception conditions like urban canyons, overhead foliage, tunnels and parking garages. It integrates an embedded array of sensors including accelerometers, gyroscopes and a barometer (pressure sensor).

    An antenna ON, antenna sense (open / short circuit) feature, allows the host application to inform the user of problems with the connection to the external antenna. An additional LNA delivers better sensitivity in harsh environments, better enabling devices with integrated antennas. The module also features fast calibration and is pin-to-pin compatible with the SL869, SL869-V3 and SL869-ADR.

    Below is a video where performance the autonomous SL869-3DR MoDR is compared with the SL869-ADR automotive navigation module connected to vehicle sensors (wheel ticks and reverse signal).

  • U-blox cellular module integrates GNSS with LTE modem for IoT

    U-blox cellular module integrates GNSS with LTE modem for IoT

    U-blox has launched the LARA-R3121, a new module comprising a single-mode LTE Category 1 modem and a GNSS positioning engine specifically designed for Internet of Things (IoT) and machine-to-machine (M2M) devices.

    The LARA-R3121 is designed for IoT applications including smart utility metering, connected health and patient monitoring, smart buildings, security and video surveillance, smart payment and point-of-sale (POS) systems, as well as wearable devices, such as action cameras.

    “Most IoT modules on the market use LTE modem technology, developed by handset-focused silicon vendors. They may not provide the best fit for IoT applications, because they focus on features targeted at Tier 1 handset makers, limited by short life cycles. The LARA-R3121 is different with features and qualifications crafted for the industrial markets,” said Andreas Thiel, u-blox co-founder and executive VP, Cellular Products and IC Design. “This is the only cellular module comprising a LTE Cat 1 modem and a GNSS engine, with complete module hardware and software all developed by a single supplier. With our focus on the IoT market, we bring an ‘IoT first’ approach to silicon design.”

    The LARA-R3121 is supplied in the small 24 x 26 mm LARA LGA form factor for compact IoT devices. This standardized package enables straightforward automated manufacturing and is pin-compatible with the u-blox LARA-R2 series, which supports multimode LTE Cat 1 with 2G/3G fallback.

    LARA-R3121 module by u-blox.
    LARA-R3121 module by u-blox.

    According to the company, it is a landmark in u-blox’s long-term strategy to create modules based on the UBX-R3 LTE modem technology platform, an internally developed, flexible, software-defined modem architecture specifically designed for IoT and M2M.

    The essential modem, positioning and module components of the LARA-R3121 are developed in-house, allowing for freedom for innovative feature development, for enabling end-to-end security and giving full control of product quality, while ensuring the long term product availability required by many IoT applications. Because modem and GNSS technologies were all developed in-house, u-blox is also able to provide unparalleled technical support for developers.

    The LARA-R3121 features FOTA, providing customers with a solution to issue firmware over the air updates. It also benefits from end-to-end security features, such as secure boot, secure transport layer, secure authentication, secure interfaces and APIs. Like other cellular modules from u-blox, it complies with a nested architecture, which allows for easy migration, and future-proof, seamless mechanical scalability across cellular technologies.

    As a single mode, LTE-only device, LARA-R3121 takes advantage of the fact that LTE networks are becoming universally available. Increasingly, products do not require fallback to 3G or 2G, which means that non-essential components can be removed, reducing cost and power consumption.

    The 10 Mbits downstream and 5 Mbits upstream maximum throughput of LTE Cat 1 provides data rates sufficient for good quality video streaming.

  • HellaPHY wireless positioning better than 50 meters for IoT

    Acorn Technologies Inc., a semiconductor and wireless technology company focused on the Internet of Things (IoT), has developed and  demonstrated new wireless long-term evolution (LTE) positioning technology for the location of things. The LTE location-based technology meets the new Enhanced 911 (E911) mandate performance requirements and performs well in very low bandwidth conditions. HellaPHY technology provides better than 50-meter accuracy for next generation location of things in the machine-type communications (MTC) and IoT markets.

    Location of devices acts as an organizing principle for anything connected to the internet, helping organize the billions of internet-connected devices based on the sensors and other location-centric elements in them. The installed base of IoT endpoints will grow to more than 25 billion in 2019, hitting 30 billion in 2020, according to a recent IoT forecast.

    “We are achieving accuracy in low bandwidth scenarios,” says Steven Caliguri, VP of wireless products at Acorn Technologies. “We believe that our advanced LTE positioning solution is the lowest complexity, lowest cost and lowest power solution available today for LTE based applications from high-end smartphones to loT.”

    Acorn has demonstrated better than 50-meter accuracy in live network testing of their user equipment (UE)-based positioning algorithms for low bandwidth CAT-M devices. (Cat-M refers to Category M, the second generation of LTE chipsets meant for IoT applications.) The network tests were conducted on a network that has not been fully optimized for LTE-based positioning.  Further gains are expected when optimizations begin to rollout.

    Acorn’s network testing has demonstrated the ability to exceed the 2021 E911 mandated performance requirements even in low-bandwidth scenarios.

    The technology has been developed from the core hellaPHY Channel Estimation algorithm that employs machine-learning techniques. The positioning algorithms are  suited for IoT applications due to their extremely low complexity, and require less then 10 kilobytes of memory and only a fraction of a low-end DSP during the maximum processing interval. It has further proven to exceed the performance of super resolution algorithms at a fraction of the complexity.

    HellaPHY RSTD is an advanced signal processing algorithm that was developed to improve LTE wireless network indoor and outdoor location accuracy. It is designed to be a drop-in replacement for existing Reference Signal Time Difference (RSTD) algorithms in UE chipsets and can be customized for any unique DSP or interface requirements. The hellaPHY RSTD IP core is designed to support advanced LTE features contemplated by operators as well as for LTE Release 14 including Positioning Reference Signals (PRS) muting, Cell-Specific Reference Signal (CRS) plus PRS transmit diversity, and fractional Ts reporting. The hellaPHY RSTD IP core is scalable and can support CAT-M through CAT-15.

    (” … the ubiquitous parameter Ts. This nameless parameter is the most basic unit of time in the LTE air interface and pretty much everything in the LTE frame structure is based on multiples of this basic time unit, capital “T”, sub small “s”. Ts is defined exactly as: Ts = 1/(15000 x 2048) seconds, a little more than 32 nano-seconds.”

    “The NINA-B1, in combination with the Wirepas Connectivity software, enables short time to market for easy-to-install, large scale, decentralized industrial IoT applications in segments such as lighting, sensor, asset tracking and beacons,” says Hakan Svegerud, head of product strategy, short range radio, at u-blox.

    “We believe that technology should never be the starting point; instead, we should concentrate on business and application needs,” says Wirepas CEO Teppo Hemiä. “As needs evolve over time, so should the technology. Wirepas and u-blox share this core value and that is what makes us stronger together.”

  • Rambus and Movimento team on personalized security for automotive

    Rambus Inc. and Movimento are partnering to deliver secure, personalized over-the-air (OTA) vehicle updates critical to safety and performance in the era of the connected car.

    Rambus is a specialist in digital security that provides a secure foundation for a connected world, and Movimento specializes in OTA software lifecycle and data management for the automotive/IoT sectors.

    Movimento and Rambus are demonstrating the joint solution at TU-Automotive in Detroit. Visitors can see how the solution works on a live demo using a Dodge RAM truck in Movimento’s booth C67.

    Moviemento also took home a TU-Automotive Award for Best Telematics Product/Service for its OTA platform.

    The CryptoManager platform adds an important layer of security to the Movimento OTA solution. Vehicle updates provided by the combined Movimento and Rambus solution offers one-time, single-use keys unique to each vehicle, minimizing vulnerabilities and maximizing security.

    As part of the collaboration, Movimento’s OTA technology uses the Rambus CryptoManager platform, enabling in-field provisioning of encrypted keys generated for each vehicle and allowing for secure communication between a vehicle and the cloud.

    “As cars continue to increase in complexity and connectivity, often depending on more than 100 million lines of code to function, car makers and consumers alike are demanding simple and secure methods to download, authenticate and install vehicle updates,” said Mahbubul Alam, CTO of Movimento. “By partnering with Rambus and integrating the CryptoManager security platform with Movimento’s OTA solutions, we are able to further our strategy of building a best-in-class ecosystem of integrated solutions to enable the software defined car and data analytics.”

    Movimento’s tools and technologies are designed to reduce complexity when making software and firmware updates by updating all the ECUs in a car in one go securely. From the chip to the cloud, Movimento builds on more than a decade of experience in automotive industry with the company updating more than 3 million vehicles every year.

    “Many current OTA solutions deliver functional updates and security patches for vehicles using the same software encryption key for multiple vehicles, increasing the vulnerability of the update,” said Martin Scott, general manager of the Rambus Cryptography Research Division. “The Rambus CryptoManager solution provides an integrated security platform with flexible implementation from the hardware root-of-trust to the secure firmware which, when combined with Movimento’s OTA technology, enables the next level of integrated chip-to-cloud-to-car security.”

    The CryptoManager platform allows for cost reduction by enabling security features already embedded in automotive chipsets and requires no additional security hardware. By utilizing an embedded hardware solution, the CryptoManager platform minimizes the attack surface of the vehicle by providing end point security.
