# Signature Relay for firmware
Documentation of
Documentation of the Assignment 7 in Systems Security at Ruhr-Universität Bochum.
This is a program, that uses a TEE to build a signature relay to sign firmware with a master key.
For more informationm, read the [project description](doc/abgabe.pdf).
We recommend viewing the [repository](https://git.pfzetto.de/RubNoobs/Systemsicherheit/src/branch/Assignment-7-sgximpl/7-SGX_Hands-on) we worked on together at.

The enclave verifies the employee signature and signs the firmware if the signature is valid.
3. Verify signature using `cat <proxy_signature.der> | ./signatureproxy embedded -firm <firmware.bin> -ppub <proxy_public_key.pem>`
This step can also be done using OpenSSL: `openssl dgst -sha256 -verify <proxy_public_key.pem> -signature <proxy-signature.der> <firmware.bin>`
