Scope:

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.

Project need:

To review the Standard within the required 5 year period.
