Basic knowledge CBC flip attack Introduction: When one of our values C is obtained by the exclusive or of A and B C = A XOR B that A XOR B XOR C is obviously = 0 When we know B and C, it's easy to get the value of A A = B XOR C Therefore, A XOR B XOR C is equal to 0. With this formula, we can set our own value at the end of XOR operat ...
