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".
