  • 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.

     

  • IZT Solutions’ over-the-air system tests GNSS receiver performance

    German research organization Fraunhofer Gesellschaft has developed and presented an over-the-air (OTA) wave-field synthesis system for test and certification of GNSS receivers. The testing platform is at its Fraunhofer IIS Facility for Over the Air Research and Testing (FORTE) in Ilmenau, Germany.

    The innovative and complex OTA test system is based on hardware and software solutions from IZT GmbH, such as powerful RF receivers and high-performance signal generators.

    The demonstrated setup to test GNSS receivers represents a new approach that — in contrast to conventional conducted and open-field tests — realistically emulates real-world scenarios under controllable and repeatable conditions, enabling the realistic comparison of receivers and algorithms. The OTA test system is cost-effective, flexible and scalable.

    The newest generations of mobile communication systems employ multiple antennas for transmission and reception, such as LTE, LTE-A, WIMAX and Wireless LAN. Multiple Input Multiple Output (MIMO) OTA test systems are typically deployed for certification, performance testing and product evaluation of broadband wireless devices. The related devices have to be tested in their related environments.

    In contrast to mobile phones, GNSS receivers are extremely susceptible to all types of interference. Hence, the goal was to develop a new testing method for interference robustness of GNSS receivers.

    The OTA Test Approach

    The OTA test laboratory comprises a satellite signal emulator (Spirent) used as signal source, several OTA channel emulators used for wave-field synthesis that are able to emulate any electromagnetic environment in an anechoic chamber, and several OTA illumination antennas. The OTA channel emulators from IZT GmbH support 8 input and 32 phase coherent output channels (up to 256 logical channels) in the frequency range of 1 to 6 GHz, and provide the output signals to the OTA illumination antennas. Note that the final extension of the system based on the IZT components will have 12 x 32 channels.

    The unique test environment developed at FORTE together with IZT GmbH excels in its great flexibility regarding possible applications in communications technology. The new OTA emulation approach enables realistic radio channel emulation taking into consideration multipath propagation, multi-frequency, and multi-user scenarios.

    The OTA system supports emulation of complex channel impulse responses of nearly unlimited length. Besides GNSS equipment, the test system can be applied for LTE and Cognitive Radio (CR), sensor networks (including energy networks and smart metering) or car-to-car and car-to-infrastructure communications.

    The Innovationszentrum für Telekommunikationstechnik GmbH IZT is a spin-off of the Fraunhofer-Gesellschaft, Germany’s leading institution for applied research. Founded in 1997 in Erlangen, the company emanated from the Fraunhofer Institute for Integrated Circuits (IIS). It specializes in advanced digital signal processing and field programmable gate array (FPGA) designs in combination with high-frequency and microwave technology.
