STMicroelectronics has announced the new STSAFE-VJ100-CCC system-on-chip platform designed to accelerate the introduction of digital car keys giving consumers keyless access to vehicles via their mobile devices. STSAFE-VJ100-CCC is an embedded secure element (eSE) based on the Java Card platform and is integrated with “Digital Key” and “UWB Services” applications in compliance with CCC Digital Key Release 3 specification.
This in-vehicle system-on-chip solution is based on CC EAL6+ certified, automotive-grade 2 ST33K-A secure IC, integrating Java Card applications. The SoC stores credentials and other sensitive information, and performs cryptographic operations required to implement CCC Digital Key Release 3 use cases like owner pairing, key sharing, and key termination/deletion.
