Henon chaotic theory based image encryption and decryption for real time applications

Cryptography is a necessary tool to protect the confidential data. It is important to secure data against active and passive attacks. A better way to protect the data is creating an encrypting algorithm to hide from third party to access data. It provides privacy, high security and more efficient. In this paper, chaotic cryptographic method is proposed for real time environment. In initial condition, chaotic signals show random behaviour and they are very sensitive. Chaotic method does not provide high security level because of single key. The chaos technique includes two stages of operation key principle. Fast encryption method provides good efficiency. The result gives the effective analysis for heuristics attacks.
