This document specifies digital signature mechanisms with appendix whose security is based on the discrete logarithm problem.This document provides— a general description of a digital signature with appendix mechanism, and— a variety of mechanisms that provide digital signatures with appendix.For each mechanism, this document specifies— the process of generating a pair of keys,— the process of producing signatures, and— the process of verifying signatures.Annex A defines object identifiers assigned to the digital signature mechanisms specified in this document, and defines algorithm parameter structures.Annex B defines conversion functions of FE2I, I2FE, FE2BS, BS2I, I2BS, I2OS and OS2I used in this document.Annex D defines how to generate DSA domain parameters.
