ISO/IEC 9796-3:2000
Information technology -- Security techniques -- Digital signature schemes giving message recovery -- Part 3: Discrete logarithm based mechanisms
This part of ISO/IEC 9796 specifies two randomized digital signature schemes giving message recovery. The security of both schemes is based on the difficulty of the discrete logarithm problem. The first scheme is defined on a prime field and the second one on an elliptic curve.
This part of ISO/IEC 9796 also defines a redundancy scheme using hash-codes and specifies how the basic signature schemes are to be combined with the redundancy scheme.
This part of ISO/IEC 9796 also defines an optional control field in the hash-token, which can provide added security to the signature.
