Class HQCParameterSpec

java.lang.Object

iaik.security.pq.provider.PQAlgorithmParameterSpec

iaik.security.pq.hqc.HQCParameterSpec

All Implemented Interfaces:

AlgorithmParameterSpec

public class HQCParameterSpec
extends PQAlgorithmParameterSpec

Implements the AlgorithmParameterSpec interface for the HQC [0] KEM. It defines the getter methods for the defined parameters. These implementation was adopted from the C reference implementation by [0].

Constructor Detail

HQCParameterSpec

public HQCParameterSpec()

This is the default constructor for the HQC parameter spec.

HQCParameterSpec

public HQCParameterSpec(HQCParameterSpec.ParameterSets parameterSet)
                 throws PQRuntimeException

Define the parameter spec for HQC by the parameter set.

Parameters:

parameterSet - The given parameter set

Throws:

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

HQCParameterSpec

public HQCParameterSpec(SecurityLevel securityLevel)
                 throws NullPointerException

Define the parameter spec for HQC 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

HQCParameterSpec

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

Define the parameter spec for HQC by the algorithm ID.

Parameters:

algorithmID - The given algorithm ID

Throws:

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