Class AKOT15SharedPublicParameters

java.lang.Object

org.cryptimeleon.craco.sig.sps.SPSPublicParameters

org.cryptimeleon.craco.sig.sps.akot15.AKOT15SharedPublicParameters

All Implemented Interfaces:

java.lang.Cloneable, PublicParameters, org.cryptimeleon.math.serialization.Representable, org.cryptimeleon.math.serialization.StandaloneRepresentable

Direct Known Subclasses:

SPSXSIGPublicParameters, TCGAKOT15XSIGPublicParameters

public class AKOT15SharedPublicParameters
extends SPSPublicParameters
implements java.lang.Cloneable

The construction of the AKOT15 signature scheme SPSFSP2SignatureScheme requires the PublicParameters to match up across building blocks. In order to simplify interactions between the schemes, this class holds these shared public parameters.
