This approach is mainly to prevent Known-Messages-Attack against ElGamal signature and its variants. This work is an amelioration of ElGamal digital signature in the group multiplicative, the elliptic curves and their variations. </style></abstract><section><style face="normal" font="default" size="100%">117</style></section></record></records></xml>
