Class AIMerSigner

java.lang.Object
org.bouncycastle.pqc.crypto.aimer.AIMerSigner
All Implemented Interfaces:
MessageSigner
public class AIMerSigner extends 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.

References:

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.

  • Method Details

    • 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
