WebThe Platform Security Architecture (PSA) API is initialized. A random Elliptic Curve Cryptography (ECC) key pair is generated and imported into the PSA crypto keystore. The public key of the ECDSA key pair is imported into the PSA crypto keystore. ECDSA signing and verification: Signing is performed using the private key of the ECC key pair. WebThe Crypto driver provides a public API to perform cryptographic and hash operations, as well as generate both true and pseudo random numbers. It uses a hardware IP block to accelerate operations.
