An Image Encryption Algorithm with XOR and S-box
نویسندگان
چکیده
This new algorithm performs lossless image encryption by combining variable-length key-dependent XOR encryption with S-box substitution. This algorithm was implemented and tested by performing different permutations of XOR encryption and S-box substitution. Empirical analysis using different types of test images of different sizes showed that this new algorithm is effective and resistant to statistical attacks. The idea presented by this algorithm may be generalized to apply to input data other than images, and may be combined with other encryption methods.
