Rambus & Movimento team to deliver personalized OTA security for automotive; one-time, single-use keys unique to each vehicle

Digital security provider Rambus and Movimento, leading provider of over-the-air (OTA) software lifecycle and data management for the automotive/IoT sectors, have partnered to deliver secure, convenient and personalized OTA vehicle updates critical to safety and performance in the era of the connected car.

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

As part of the collaboration, Movimento’s OTA technology utilizes 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.

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.

—Mahbubul Alam, CTO of Movimento

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 three 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. 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.

—Dr. Martin Scott, general manager of the Rambus Cryptography Research Division

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.

Movimento’s car manufacturer customers include Ford, GM, FCA and Volvo plus a wide range of Tier-1 suppliers including ZF, Bosch, Denso, Panasonic, Continental, Delphi, Visteon, Magna and others. The company is headquartered in Plymouth, Michigan, with offices in the Silicon Valley, Mexico, Sweden, Germany and Asia Pacific.

The Rambus Cryptography Research division technologies span areas including tamper resistance, content and media protection, network security, and secure payment and transaction services. These technologies protect nearly nine billion licensed products annually.
