1 Scope
This part of ISO/IEC 14888 specifies digital signature mechanisms with appendix whose security is based on the discrete logarithm problem.
This part of ISO/IEC 14888 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.
