RC 4 Enrichment Algorithm Approach for Selective Image Encryption

This paper is introduces RC4 Enrichment Algorithm Approach for selective image encryption. This approach is derived from the standard RC4 algorithm. RC4 algorithm is already used for image encryption and also for the selective image encryption. Currently RC4 is vulnerable. Lots of cryptanalytic found the lots of weakness, vulnerable point and attacks inside the RC4 algorithm. So in this concern, this paper has worked. This paper has designed the RC4 based new enrichment approach to making strong the RC4 algorithm, “PC1-RC4”. This approach is based on new KSA and PRGA algorithm process, which are the two stages inside the RC4 algorithm.
