Arun and Murugab [14] proposed combined LSB steganography techniques with XOR substitution operations on RGB images. This method is very simple LSB which is secured by XOR operation with an 8-bit random key. WebDoes it really matter if we used AND, OR or XOR with the one-time pad? The answer is yes, and it’s extremely important to understand why. Recall from the previous article that AND has a 75% chance of outputting 0 and a 25% chance of outputting a 1. While OR has a 25% chance of outputting 0 and 75% chance of outputting 1. earthquake in central california
