Abstract:
RC4 algorithm is a famous stream cipher. It could be used to encrypt images quickly and efficient. However, the RC4 has been proved has some drawbacks, therefore it is considered not secure anymore. Therefore, RC4 algorithm needs to be improved the security. This paper describes an improved RC4 algorithm based on multi chaotic map (Logistic map, Henon map, and Sine map) to and use it to encrypt the images. RC4 algorithm consists of KSA stage and PRGA stage. Modification of KSA stage has been done using the chaotic maps. Performances of the improved RC4 for image encryption were measured by some metrics (histogram, correlation, and entropy). Experiment results show that the improved RC4 has good performance for image encryption.
