40.8. Algorithm of error detection and correction ECC-DSA

40.8.1. Overview

ecc_dsa_example the example project shows the implementation of error detection and correction algorithm ECC. - The error detection and correction algorithm of this project adopts ECC DSA to complete the module encryption and decryption test.

40.8.2. Board Setting

• No special settings

40.8.3. Running the example

When the project runs correctly, and the serial port terminal will output the following information:
