Class SPSXSIGSigningKey

java.lang.Object

org.cryptimeleon.craco.sig.sps.akot15.xsig.SPSXSIGSigningKey

All Implemented Interfaces:

SigningKey, org.cryptimeleon.math.serialization.Representable

public class SPSXSIGSigningKey
extends java.lang.Object
implements SigningKey

A signing key as generated by the SPSXSIGSignatureScheme. Note: V6 is part of the verification key, but as it is used for signature calculation, the groupElement is also stored here.
