N2 - The increasing importance of security of multimedia data has prompted greater attention towards secure image encryption algorithms. In this paper, the authors propose a highly secure encryption algorithm with permutation-substitution architecture. In the permutation step, image pixels of the plain image are shuffled using Linear Feedback Shift Register (LFSR). The output of this step is an intermediary cipher image which is of the same size as that of the plain image. In the substitution step, sequence of random numbers is generated using the RC4 key stream generator which is XORed with the pixel value of the intermediary cipher image to produce the final cipher image. Experimental results and security analysis of the proposed scheme show that the proposed scheme is efficient and secure.
