The primary reason XOR is so useful in cryptography is because it is "perfectly balanced"; for a given plaintext input 0 or 1, the ciphertext result is equally likely to be either 0 or 1 for a truly random key bit. The table below shows all four possible pairs of plaintext and key bits. It is clear that if nothing is known about … See more In cryptography, the simple XOR cipher is a type of additive cipher, an encryption algorithm that operates according to the principles: A $${\displaystyle \oplus }$$ 0 = A, A For example where See more • Block cipher • Vernam cipher • Vigenère cipher See more The XOR operator is extremely common as a component in more complex ciphers. By itself, using a constant repeating key, a simple XOR cipher … See more Example using the Python programming language. See more WebAug 5, 2024 · XOR cipher employs the XOR logical operation in order to encrypt data. First, a random key is generated. Then, XOR operation is performed using the key so that an …

WebJun 7, 2002 · Basic XOR. The XOR operation denoted by + is a bit-wise function that maps an element of {0, 1}x {0,1} onto the set {0, 1} as follows: 0 +0 =0 0 +1 =1 1 +0 =1 1 +1 =0. If we take the second operand to be a key value, the XOR operation can be thought of as being simply a bit-level substitution based upon the bit values of the key. WebJul 1, 2024 · 1 Answer.
