Summary

This documentation describes the usage of security features for microcontrollers especially for the Atmel Sam R21 with the expansion board Atcryptoauth Xpro B.

Requirements

Description

The Cryptoauth expansion board contains four chips which gets connected via I2C Chips:

Implementation for ATECCx08A and ATSHA204A

The implementation for ATECCx08A and ATSHA204A is based on the Cryptoauthlib.For ease of use of the ASF USART a custom abstraction layer got implemented.

The example program Implements:

  • Showing the serial numbers of the chips
  • Hashing a message
  • Showing locked zones
  • Locking zones
  • Generate a random number (only works with locked configuration Zone)
  • Generate a keypair (only works with locked configuration Zone)

Usage:

  • Connect your microcontroller to the EDGB USB port and upload the software
  • Open a terminal Program (Putty, TeraTerm)
  • Terminal program configuration:
  Baud rate     115200
  Data bits     8
  Stop bits     1
  Parity        none
  • Press the restart button in the controller
  • The implementation has an text menu which allows you to navigate by numbers
