A Novel Encryption Algorithm for Transmitting Secure Data Based on Genetic Hyper Chaos Map
A new color image encryption algorithm based on chaos genetic algorithm and control parameter chaotic map is proposed in this paper. Four chaotic sequences are generated from a 4D hyper chaos. To increase the security of the cryptosystem, Tent map is used to produce the control parameter, and the cubic map is used to get the chaotic sequence to produce the number of iterations. Performance analysis show that the proposed scheme achieve large key space, good statistical character, and can against brute-force attack, differential attack and entropy attack efficiently. The scheme possesses good performance in encryption/encryption speed and is suitable for real-time image encryption and transmission.
