I want to evaluate cryptographic algorithms on the boot loader before Linux starts up. We plan to include evaluation software in ARM Trusted Firmware (bl31-h3ulcb). ARM Trusted Firmware has no encryption algorithm, so we are considering using a library in OP-TEE (tee-h3ulcb). For example, in evaluating signature verification using RSA, the following processing is considered necessary. ・ Register the public key and secret key. ・ And generates a hash value of the evaluation target data. (For example SHA 256) ・ Generate a signature by encrypting the hash value with the secret key. ・ Generate a hash value by decrypting the signature with the public key. Among these processes, I do not know how to register the public key and secret key to OP-TEE. Please tell me what kind of processing can be realized from ARM Trusted Firmware.
