Encryption Image by Using RC6 and Hybrid Chaotic Map


Zahraa Faisal and Esraa H. Abdul Ameer

Abstract

Cryptography is data processed in a way that becomes incomprehensible and unavailable to unauthorized persons. In this paper instructed method to encryption image by using RC6 algorithm and generated key by using hybrid chaotic map (tent and logistic map). Used some measures such as frequency test within a block, entropy, serial test (two-bit test), and frequency test (monobit test); to demonstrate the strength of the algorithm proposed in the image coding and protection. The MATLAB program was used as a work environment.
