Abstract

This paper present a security analysis of the proposed selective image encryption algorithm based on chaos and CBC-like mode. The algorithm uses a Logistic Map to generate kesytreams that XOR-ed with 4-bit MSB of each pixel. Security analysis covers key space analysis, histogram analysis, correlation analysis, entropy analysis, and sensitivity analysis. Based on experiment results and the security analysis can be concluded that the proposed algorithm is secure from various attacks which aim to find the secret keys or pixels in plain-images.
