Class AIMerSigner

java.lang.Object
  org.bouncycastle.pqc.crypto.aimer.AIMerSigner

All Implemented Interfaces:

MessageSigner

public class AIMerSigner

extends java.lang.Object

implements MessageSigner

Implementation of the AIMer digital signature scheme as specified in the AIMer documentation. This class provides low-level cryptographic operations for both signature generation and verification, including finite field arithmetic over GF(2^128), GF(2^192), and GF(2^256), matrix generation, MPC-based proofs, and the AIM2 block cipher.

AIMer is a selected algorithm in the Korean Post-Quantum Cryptography (KPQC) project.

This engine supports three security levels (128, 192, and 256 bits), each with fast and small variants. The field size is automatically selected based on the provided AIMerParameters.

Constructor Summary

AIMerSigner()

Method Summary

byte[]	generateSignature(byte[] message) sign the passed in message (usually the output of a hash function).
void	init(boolean forSigning, CipherParameters param) initialise the signer for signature generation or signature verification.
boolean	verifySignature(byte[] message, byte[] signature) verify the message message against the signature value.

AIMerSigner

public AIMerSigner()

Method Detail

init

public void init(boolean forSigning,
                 CipherParameters param)

Description copied from interface: MessageSigner

initialise the signer for signature generation or signature verification.

Specified by:

init in interface MessageSigner

Parameters:

forSigning - true if we are generating a signature, false otherwise.

param - key parameters for signature generation.

generateSignature

public byte[] generateSignature(byte[] message)

Description copied from interface: MessageSigner

sign the passed in message (usually the output of a hash function).

Specified by:

generateSignature in interface MessageSigner

Parameters:

message - the message to be signed.

Returns:

the signature of the message

verifySignature

public boolean verifySignature(byte[] message,
                               byte[] signature)

Description copied from interface: MessageSigner

verify the message message against the signature value.

Specified by:

verifySignature in interface MessageSigner

Parameters:

message - the message that was supposed to have been signed.

signature - the signature of the message
