Abstract :
In this paper, a novel image cascaded encryption algorithm based on chaotic system is proposed. Henon-Logistic Cascaded Algorithm (HLCA) is implemented by Henon map and Logistic map which can simultaneously perform in two processes of image encryption, via pixel value substitution and pixel position permutation. More importantly, with the assistance of extra secret key, enormous cipher capacity is realized as to make the cipher more robust against any attack. Experimental results show good performance of this cipher algorithm in aspects of key space, key sensitivity, pixel disordering and anti-attack ability. On the other hand, a new image scrambling degree evaluation criterion is introduced in this paper which can assess the security of the cipher algorithm proposed effectively, shown by related experimental results.
