Cipher Demo

Overview

This section covers the security-related samples under sample_cipher, including AES, software hash, hardware hash, and PUF-based flows.

Source Paths

• src/rtsmart/examples/mpp/sample_cipher/sample_aes

• src/rtsmart/examples/mpp/sample_cipher/sample_hash

• src/rtsmart/examples/mpp/sample_cipher/sample_hwhash

• src/rtsmart/examples/mpp/sample_cipher/sample_pufs

Build

Enable the following items in make menuconfig:

• RT-Smart UserSpace Examples Configuration

• Enable MPP examples

• Enable Build sample_cipher

Run

cd /sdcard/app/examples/mpp
./sample_aes.elf
./sample_hash.elf
./sample_hwhash.elf
./sample_pufs.elf

Notes

• sample_aes tests /dev/aes related flows

• sample_hash uses the software hash path

• sample_hwhash uses the hardware hash path

• sample_pufs demonstrates PUF encryption, decryption, and signing flows
