public class LMOTSKeyPairGenerator

extends KeyPairGenerator

This class generates the public- and the private key pairs. It randomly and uniformly chooses the private key pair and calculates the public key pair as the hash of the private keys.

Method Detail

genKeyPair

public KeyPair genKeyPair()

Generates an LMOTS key pair, consisting of an LMOTSPublicKey and an LMOTSPrivateKey.

Overrides:

genKeyPair in class KeyPairGenerator

Returns:

the generated key pair

initialize

public void initialize(AlgorithmParameterSpec params,
                       SecureRandom javaRand)
                throws InvalidAlgorithmParameterException

Initialize the key pair generator.

Overrides:

initialize in class KeyPairGenerator

Parameters:

params - the parameters

javaRand - the source of randomness

Throws:

InvalidAlgorithmParameterException - if the parameters are not an instance of LMOTSParameterSpec.

initialize

public void initialize(int keysize,
                       SecureRandom javaRand)

(NOT USED! SEE LMOTSParameterSpec) Initialize the key pair generator with the given seed size and source of randomness.

Overrides:

initialize in class KeyPairGenerator

Parameters:

keysize - the seed size in bits

javaRand - the source of randomness
