Overview

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, RX66T 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.

Topics

The Trusted Secure IP Driver V.1.06 has been released. RSA Key generation (RSA 1024 bit, 2048 bit), Key update functions supporting theRX65N is now available.
