Design of generalised ElGamal type digitalsignature schemes based on discrete logarithm
Lein Harn, Yanyan Xu · Electronics Letters · 1994
The ElGamal type digital signature schemes have received wide attention recently. ElGamal type signature schemes can provide ‘subliminal’ channel, message recovery, multisignature, etc. The authors investigate the design criteria of ElGamal type signature scheme and develop a complete list of all variations.
