Image Encryption using Modified RC4 Algorithm

In this paper, we propose a new method for image encryption based on a modified RC4 stream cipher algorithm that scrambles image pixels before applying the XOR encryption function. We compare the performance of the proposed modified RC4 algorithm with that of the standard RC4 algorithm by analyzing histograms, calculating the correlation coefficient between adjacent pixels, and measuring information entropy. The results demonstrate that the proposed algorithm outperforms the standard RC4 algorithm in terms of resistance to statistical attacks.
