Interface SM9SigUserKeyParametersGenerator

All Known Implementing Classes:
SM9SigMasterPrivateKeyParameters
public interface SM9SigUserKeyParametersGenerator
A master key capable of the KGC user-key extraction for an identity-based signature scheme: deriving a user's signature private key from the user's identity (GM/T 0044.2-2016 for SM9, where the signature private-key generation function identifier hid is applied internally).

    SM9SigPrivateKeyParameters
    generateUserKey(byte[] identity)
    Derive the signature private key of the user identified by identity, a deterministic KGC operation - the same master key and identity always yield the same user key.
