public class ECCSIPrivateKeyParameters
extends AsymmetricKeyParameter

Represents the private key parameters for the Elliptic Curve-based Certificateless Signature Infrastructure (ECCSI) scheme as defined in RFC 6507.

This class encapsulates the secret signing key (SSK) used in ECCSI. The SSK is generated by the Key Management Service (KMS) and is a random integer modulo the order of the elliptic curve. It is paired with the corresponding public key parameters, represented by an instance of ECCSIPublicKeyParameters, to form the complete key material required for generating and verifying ECCSI signatures without the use of traditional certificates.

Per RFC 6507 Section 5.1:

• The SSK is generated as a random value in the appropriate range.
• It is used in conjunction with the public validation token (PVT) to perform signature operations.
• The combination of the SSK and the public key parameters enables certificateless signature generation and verification.
