Class KyberParameterSpec

java.lang.Object

iaik.security.pq.provider.PQAlgorithmParameterSpec

iaik.security.pq.kyber.KyberParameterSpec

All Implemented Interfaces:

AlgorithmParameterSpec

public class KyberParameterSpec
extends PQAlgorithmParameterSpec

Implements the AlgorithmParameterSpec interface for the Kyber [0] KEM. It defines the getter methods for the defined parameters. See the implementations of this interface for the different instantiations defined by [0] in Section 1.4. Is being updated according to FIPS 203 Draft [1].

Constructor Detail

KyberParameterSpec

public KyberParameterSpec()

This is the default constructor for the Kyber parameter spec.

KyberParameterSpec

public KyberParameterSpec(KyberParameterSpec.ParameterSets parameterSet)
                   throws PQRuntimeException

Define the parameter spec for Kyber by the parameter set.

Parameters:

parameterSet - The given parameter set

Throws:

PQRuntimeException - if the given KyberParameterSpec.ParameterSets is not a valid parameter set

KyberParameterSpec

public KyberParameterSpec(SecurityLevel securityLevel)
                   throws NullPointerException

Define the parameter spec for Kyber by the security level. If a security level 2 or 4 is chosen the next higher security level will be used which is level 3 or 5.

Parameters:

securityLevel - The given security level

Throws:

NullPointerException - if the given SecurityLevel is null

KyberParameterSpec

public KyberParameterSpec(iaik.asn1.structures.AlgorithmID algorithmID)
                   throws PQException

Define the parameter spec for Kyber by the algorithm ID.

Parameters:

algorithmID - The given algorithm ID

Throws:

PQException - if an error occurs because not valid algorithmID was given
