Cipher Demo

Introduction

This chapter corresponds to the security capability examples under the sample_cipher directory, mainly covering AES, Hash, hardware Hash, and PUF related capabilities.

Code Location

• 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

Compilation Method

Enable the following options in make menuconfig:

• RT-Smart UserSpace Examples Configuration

• Enable MPP examples

• Enable Build sample_cipher

Then execute the firmware compilation.

Running Examples

After compilation, multiple executable files will be generated (named after the subdirectories):

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

Description

• sample_aes mainly verifies the /dev/aes related workflows.

• sample_hash demonstrates the software hash workflow.

• sample_hwhash demonstrates the hardware hash workflow.

• sample_pufs demonstrates the PUF encryption/decryption/signature related workflows.
