## Security peripherals test

This is a combined security peripherals verification application using mostly HAL APIs. This application is intentionally kept simple and does not use any higher layer constructs. This application can help in the early verification of the new SoC.

This contains tests for the following features of the security peripherals:

- MPI peripheral
    - MPI Modular Multiplication
    - MPI Multiplication
    - MPI Modular Exponentiation

- ECC peripheral
    - ECC Point multiplication for P192 and P256 curve
    - ECC Point verification for P192 and P256 curve
    - ECC Point verify and multiply for P192 and P256 curve
    - ECC Inverse multiplication for P192 and P256

    If the hardware supports extended work modes then it also tests:
    - ECC Jacobian multiplication for P192 and P256 curve
    - ECC Jacobian verification for P192 and P256 curve
    - ECC Point verification and Jacobian multiplication for P192 and P256 curve
    - ECC Point addition for P192 and P256 curve
    - Mod addition
    - Mod subtraction
    - Mod multiplication

- HMAC periperhal
    - HMAC 'downstream' JTAG Enable mode
    - HMAC 'downstream' JTAG Disable
    - HMAC 'upstream' MAC generation with zeroes
    - HMAC 'upstream' MAC generation from data


> **_NOTE:_** The verification tests for the HMAC peripherals would get exercised in only in an FPGA environment.
# Burning the HMAC key

The HMAC tests need an HMAC key to be burned in the `BLOCK_KEY3` and `BLOCK_KEY4` of the efuses. As this verification application is independent of the efuse component, the user needs to manually burn the keys and their key purposes using `espefuse.py`.

```bash
espefuse.py -p $ESPPORT burn_key BLOCK_KEY3 hmac_key.bin HMAC_DOWN_JTAG

espefuse.py -p $ESPPORT burn_key BLOCK_KEY4 hmac_key.bin HMAC_UP
```

# Building

```bash
idf.py set-target <TARGET>
idf.py build
```

# Running the app manually

```bash
idf.py flash monitor
```

Enter the test that you want to run locally

# Running tests

```bash
pytest --target <TARGET>
```
