- All Implemented Interfaces:
java.security.spec.AlgorithmParameterSpec
public class RainbowParameterSpec extends java.lang.Object implements java.security.spec.AlgorithmParameterSpec
This class provides methods for setting and getting the Rainbow-parameters like number of Vinegar-variables in the layers, number of layers and so on.More detailed information about the needed parameters for the Rainbow Signature Scheme is to be found in the paper of Jintai Ding, Dieter Schmidt: Rainbow, a New Multivariable Polynomial Signature Scheme. ACNS 2005: 164-175 (https://dx.doi.org/10.1007/11496137_12)
