The Trusted Secure IP Driver for RX Family V.1.20 has been released (Applied software workaround to avoid the HW issue of AES-CCM decryption (TSIP-Lite)).

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
  • Trusted Secure IP Driver manual
  • Sample code demonstrating application of the Trusted Secure IP Driver
    1. Sample code for confirming the way user keys are written
    2. Sample code for confirming the secure updating of firmware from USB memory or UART (In the case to use this sample code, please contact us).
    3. Sample code for confirming the way to use AES Cryptography
    4. Sample code for confirming the way to implement TLS

特性

  • Cryptographic functions which provide advanced security can be embedded in mass-produced products at low cost
  • High-speed execution of the AES, a world standard cryptographic algorithm
  • Support for AES-GCM, which is frequently included in the required specifications of smart meters
  • Functions for safely updating firmware
  • Easily combined with other device drivers for RX, RE MCUs or RZ MPUs
