Trusted Secure IP Driver
This driver controls AES, AES-GCM, AES-CMAC encryption and decryption and the generation of random numbers through high-speed hardware calculation by the Trusted Secure IP modules of RX231 Group, RX65N, RX651 Group thus equipped.
It also helps in the safe management of user keys by the Trusted Secure IP module.
These functions allow secure updating of flash ROM embedded in MCUs and in preventing illicit firmware being booted up (secure booting).
As a result, this driver can help you to protect “Internet-of-Things” (IoT) embedded devices from viral infections and eavesdropping.
