Arm CryptoCell-312 Security IP
The RSL15 system includes the Arm CryptoCell-312 IP, which is used to maintain security of the device, allow secure operation of the application firmware, and permit related user applications to access security features.
IMPORTANT: The CC312 functions, when using hardware accelerators, use a WFI instruction while waiting for the hardware accelerator to complete its processing. Therefore, these functions must not be called in the context of any interrupt routines that have a priority higher than, or equal to, the CC312 interrupt. |
IMPORTANT: The CC312 functions are not reentrant. These functions cannot be called again until their execution has been completed. |
A significant part of the Arm CryptoCell-312’s operation is based on the use of the Mbed TLS libraries.
