Digital car keys – in the ideal case, which is far from being achieved everywhere – are not only characterized by greater security, but can also offer drivers additional convenience. One example is customizable usage rights while simultaneously securing the vehicle. Applications such as car sharing, fleet management and car rental also benefit from easier key issuance, usage control and access granting for parking services or customer service, for example.

Based on ST’s latest automotive-grade security element hardware, the global solution, developed jointly with Giesecke+Devrient (G+D), supports the Car Connectivity Consortium’s (CCC) new Digital Key Standard (Release 3). This, ST advertises, realizes the highest level of security and protection currently available.

ST’s STSAFE-VJ100-CCC In-Vehicle System-on-Chip solution is based on the CC EAL6+ and Automotive ACE-Q100 Grade certified ST33K-A with integrated Java Card applications. The SoC stores credentials and other sensitive information and performs the cryptographic operations required to implement CCC Digital Key Release 3 use cases such as user pairing, key sharing and key revocation/deletion. This provides customers with a robust foundation for implementing their own digital car key solutions, ST promises.

“Leading car brands can now rapidly implement standards-based secure access solutions for their vehicles that provide added value for both vehicle owners and users,” said Laurent Degauque, marketing director, Secure Microcontrollers at STMicroelectronics. “Our solution, based on an automotive-grade embedded security element, ensures state-of-the-art protection to drive broad market adoption of digital keys for connected cars.”

“As a long-standing security and connectivity partner to the automotive sector, G+D is able to contribute its expertise in automotive access control,” said Mario Feuerer, Global Vice President Product Management Connectivity at G+D. “Our G+D Digital Key application, based on ST’s new chip platform, is highly resistant to attack and includes access solutions based on NFC, ultra-wideband and BLE that are as intelligent as they are fit for purpose.”
