ISO/IEC 14888-3:2016 specifies digital signature mechanisms with appendix whose security is based on the discrete logarithm problem.

ISO/IEC 14888-3:2016 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 part of ISO/IEC 14888 specifies

- the process of generating a pair of keys,

- the process of producing signatures, and

- the process of verifying signatures.
