We have been expanding wolfSSL’s use of NXPs CAAM (Cryptographic Acceleration and Assurance Module) on i.MX8 devices. Now it is able to use black keys with RSA operations on one of NXP’s Linux setups. To achieve this we expanded the current CAAM driver some and will post links and benchmarks shortly. Using black key’s with the CAAM are useful because they encrypt the private key and do not expose it to potentially malicious users. We are also one of the first to expand the CAAM driver for use with the new Curve25519 support. Curious how fast these operations run on the device?
