WebMar 6, 2024 · 6 Answers Sorted by: 160 XOR is a binary operation, it stands for "exclusive or", that is to say the resulting bit evaluates to one if only exactly one of the bits is set. This is its function table: a b a ^ b -- --- ------ 0 0 0 0 1 1 1 0 1 1 1 0 This operation is performed between every two corresponding bits of a number. WebTo understand why, we need to first introduce the AND, OR and XOR bitwise operations. Specifically why XOR must be used when performing the one-time pad on computers. Bitwise simply means that we are dealing with individual bits, or binary numbers.In any modern/computerized encryption scheme we represent our symbols using binary digits.
