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.

AbstractWe develop a public-key cryptosystem based on invariants of diagonalizable groups and investigate properties of such a cryptosystem first over finite fields, then over number fields and finally over finite rings. We consider the security of these cryptosystem and show that it is necessary to restrict the set of parameters of the system to prevent various attacks (including linear algebra attacks and attacks based on the Euclidean algorithm).
