For the security of the data and messages over the communicating medium, various algorithms for the security of information are widely used since the advent of communication over internet. Elliptic Curve Cryptography (ECC) is one of the most efficient techniques that are used for this issue, because it is difficult for the adversary to solve elliptic curve discrete logarithm problem to know the secret key that is used in encryption and decryption process. In this paper, we propose a modification of the Chua-Ling Cryptosystem that gives security and makes difficult for adversary to reduce that system into Rabin-William Cryptosystem . Further , We provide the authentication scheme for the system based on Digital Signature Algorithm that provides both Integrity and Authentication.
