Rambus and Movimento have teamed up to deliver secure and personalized OTA updates for connected vehicles.
As Dr. Simon Blake-Wilson, VP of Products and Marketing at Rambus Cryptography Research points out, numerous OTA solutions designed to deliver functional updates and security patches use the very same software encryption key for multiple vehicles. Essentially, this increases the vulnerability vector of an update.
In contrast, updates provided by Movimento and Rambus are delivered via one-time, single-use keys that are unique to each vehicle – effectively minimizing vulnerabilities and maximizing security. More specifically, Movimento’s OTA technology uses CryptoManager to enable in-field provisioning of encrypted keys generated for a specific vehicle, thereby facilitating secure communication between cars and the Cloud.
“CryptoManager offers an integrated security platform with flexible implementation, comprising a hardware root-of-trust and secure firmware,” Blake-Wilson explained. “When combined with Movimento’s OTA technology, CryptoManager enables the next level of integrated chip-to-Cloud-to-car security. Simply put, CryptoManager is an embedded hardware solution that minimizes the attack surface of the vehicle by providing end point security,” Blake-Wilson concluded.
Movimento CTO Mahbubul Alam expressed similar sentiments.
“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 Alam. “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.”
