Image encryption with control parameter chaotic map

An image encryption scheme based on control parameter chaotic map is proposed. To increase the security of the cryptosystem, Logistic 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 analyses 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.
