Overview
Description
Topics
The Trusted Secure IP Driver for RX Family V.1.21 has been released (Added support for TLS 1.2 server function).
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. 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".
Components
- Trusted Secure IP Driver main body
