What is this standard about?
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.
