Abstract

Cryptography addresses the necessary elements for secure communication that involved privacy, confiden-tiality, key exchange, authentication, and non-repudiation. This paper proposed a new computation of en-cryption and decryption that was based on the computation of RSA and ElGamal Cryptosystems. The RSA is a public key encryption system that gets its security from the difficulty of factoring large numbers. Meanwhile, the security of ElGamal is depends upon the difficulty of a certain problem that was related to compute Discrete Logarithms. The proposed technique shows better computation time compared to both cryptosystems. All computation time for each algorithm also presented at the end of this paper. However, this paper did not present the security of the technique over the RSA and ElGamal.
