Trusted Secure IP Driver
Overview
This product enables secure updating of flash ROM embedded in MCUs and in preventing illicit firmware being booted up (secure booting). 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 RX Family thus equipped. As a result, this driver can help you to protect "Internet-of-Things" (IoT) embedded devices from viral infections and eavesdropping. Trusted Secure IP includes a full-function version "TSIP" and limited function version "TSIP-Lite".
Topics
The Trusted Secure IP Driver V.1.08 has been released. The support for the RX72M group started. The Elliptic Curve Cryptography function is now available.
