Implementation of Various Cryptosystem Using Chaos

Cryptography is the science of secret codes, enabling the confidentiality of communication through an insecure channel to make the system more complex and robust Chaos is applied in the various cryptographic algorithms. In this paper we use most commonly used algorithm AES, RC5, IDEA, RSA, ELGamal. In this paper firstly we implement all the algorithm in MATLAB then Chaos is applied on it. After applying Chaos in these algorithms we observe that both Security and Speed increases as compare to the conventional cryptographic algorithm.
