Images scrambling using xor operator
Witrynapartitioned into blocks, which are then permuted using a permutation key. After that, the Rubik’s cube principle is applied to each block in order to obtain a scrambled image. Finally, the pixels values of rows and columns of the scrambled image are changed using XOR operator to generate the encrypted image. Witryna15 lut 2024 · The bitwise XOR operation is performed using pseudorandom numbers generated by the linear congruential method. ... Image scrambling is an important …
