The product, called STSAFE-VJ100-CCC, is a pre-programmed secured microcontroller from the company’s ST33KxxxA family – also described simply as a ‘secure element’ – which has an Arm Cortex-M35P core that comes with additional security features to help protect against advanced forms of attack, according to ST. It is automotive qualified to AEC-Q100 Grade 2, and CC EAL6+ certified.
The programming included Embedded Java Card applets developed to store credentials and other sensitive information, and perform cryptographic operations required to implement CCC Digital Key Rel.3 uses cases like owner pairing, key sharing, key termination/deletion.
“Our application, based on the new ST chip platform, is resistant to attacks and features customer access solutions based on NFC, ultra-wide-band and BLE,” said G+D v-p Mario Feuerer.
The operating system is Java Card v3.0.5 classic edition, with a CCC v3 compliant applet from G+D. It “is based on GlobalPlatform version 2.3.0, supporting SCP03 amendment D and SCP11a/c protocols amendment F, and Executable Load File Upgrade amendment H”, according to ST. “The interface defined is SPI/GP ‘APDU over SPI/I2C’ protocol and the system‑on‑chip solution includes operating system and applets upgrade mechanism.”
Operation is over -40 to 105°C and the IC comes in a 6.5 x 4.4 x 1.2mm TSSOP20.
Digital Key Release 3 features include owner pairing, key sharing and key termination/deletion.
