  org.bouncycastle.pqc.crypto.mayo.MayoKeyPairGenerator

All Implemented Interfaces:

AsymmetricCipherKeyPairGenerator

public class MayoKeyPairGenerator

extends java.lang.Object

implements AsymmetricCipherKeyPairGenerator

Implementation of the MAYO asymmetric key pair generator following the MAYO signature scheme specifications.

This generator produces MayoPublicKeyParameters and MayoPrivateKeyParameters based on the MAYO algorithm parameters. The implementation follows the specification defined in the official MAYO documentation and reference implementation.

MayoKeyPairGenerator

public MayoKeyPairGenerator()

Method Detail

init

public void init(KeyGenerationParameters param)

Description copied from interface: AsymmetricCipherKeyPairGenerator

intialise the key pair generator.

Specified by:

init in interface AsymmetricCipherKeyPairGenerator

Parameters:

param - the parameters the key pair is to be initialised with.

generateKeyPair

public AsymmetricCipherKeyPair generateKeyPair()

Generates a new asymmetric key pair following the MAYO algorithm specifications.

The key generation process follows these steps:

Initializes parameter dimensions from MayoParameters Generates secret key seed using a secure random generator Derives public key seed using SHAKE-256 Expands matrix parameters P1 and P2 Performs GF(16) matrix operations for key material generation Assembles and packages the public key components Securely clears temporary buffers containing sensitive data

Specified by:

generateKeyPair in interface AsymmetricCipherKeyPairGenerator

Returns:

A valid MAYO key pair containing public and private key parameters
