OP-TEE Sample Applications
Contents
1. Introduction
This document describes the sample applications that are included in the OP-TEE, that aim to showcase specific functionality and use case.
For sake of simplicity, all OP-TEE example test application are prefixed with
optee_example_.
2. List of sample applications
Directory hello_world/:
- A very simple Trusted Application to answer a hello command and incrementing an integer value.
- Test application:
optee_example_hello_world - Trusted application UUID: 8aaaf200-2450-11e4-abe2-0002a5d5c51b
Directory random/:
- Generates a random UUID using capabilities of TEE API (
TEE_GenerateRandom()). - Test application:
optee_example_random - Trusted application UUID: b6c53aba-9669-4668-a7f2-205629d00f86
Directory aes/:
- Runs an AES encryption and decryption from a TA using the GPD TEE Internal Core API. Non secure test application provides the key, initial vector and ciphered data.
- Test application:
optee_example_aes - Trusted application UUID: 5dbac793-f574-4871-8ad3-04331ec17f24
3. How to build a Trusted Application
