Xue Dong Dong, Xin Peng Jing · Applied Mechanics and Materials · 2014
In this paper, the extended ElGamal public key cryptosystem and digital signature scheme with appendix are described in the setting of the group of units of the ring.Elements of the group of units with the larger order are used as the base elements in the proposed extension instead of primitive roots used in the original scheme. Proposed schemes make periodic change of the group and base elements to provide necessary security level.
