Class ECCSIPublicKeyParameters

  • All Implemented Interfaces:
    CipherParameters

    public class ECCSIPublicKeyParameters
    extends AsymmetricKeyParameter
    Represents the public key parameters for the Elliptic Curve-based Certificateless Signature Infrastructure (ECCSI) scheme as defined in RFC 6507.

    This class encapsulates the Public Validation Token (PVT) required for verifying ECCSI signatures. The PVT is cryptographically bound to a user's identity and generated by the Key Management Service (KMS) as part of the key material.

    Per RFC 6507 Section 5.1:

    • The PVT is derived from the user's identity and KMS secret material
    • Used during signature verification to validate the signer's identity
    • Does not require certificates for authentication

        public ECCSIPublicKeyParameters​(ECPoint pvt)
        Constructs ECCSIPublicKeyParameters with the provided Public Validation Token (PVT).
    • Method Detail

      • getPVT

        public final ECPoint getPVT()
        Returns the Public Validation Token (PVT) for signature verification.

        The PVT is used in conjunction with the KMS Public Authentication Key (KPAK) to verify signatures per RFC 6507 Section 5.2.2.

        Returns:
        The PVT as an elliptic curve point in uncompressed format
