The reason of using XOR operation in cryptographic algorithms

WebSep 4, 2009 · XOR allows you to easily encrypt and decrypt a string, the other logic operations don't. If you have a longer string you can repeat your key until its long enough for example if your string was 1010010011 then you'd simple write your key twice and it would become 1011110111 and XOR it with the new string Here's a wikipedia link on the XOR … WebMay 20, 2011 · @Conor Mancone, Thanks for the feedback. XOR encryption can be 'reverse engineered', so that if you know 2 of the 3 variables (i.e. plaintext, key, ciphertext), you can easily find the third.

WebMar 27, 2024 · Are all stream ciphers algorithms based XOR with the key? Almost all. The reason is simple; x-or is a cheap operation and c = m ⊕ k then c ⊕ k = ( m ⊕ k) ⊕ k = m Therefore if you x-or the message with the keystream then re-xor is equal to the message. This helps to use the same logic as encryption and decryption. This reduces the cost of … WebAug 25, 2024 · The image above shows a truth table for XOR. Notice that anything XOR itself is zero, and anything XOR zero is itself. XOR is also useful in cryptography because it is equivalent to addition modulo 2. 1 + 0 = 1 and 1 + 1 = 2 = 0 (mod 2) = 0 + 0.

Choose 1 ... WebAug 25, 2024 · The principle of XOR-based VCS is to encrypt a secret image into several encrypted images, called shares. No information about the secret can be obtained from any of the shares, and after applying the logical XOR operation to stack these shares, the original secret image can be recovered.

WebJan 26, 2024 · XOR allows you to easily encrypt and decrypt a string. You cannot do this with other logical operators: backward compatibility of XOR In this article, we won’t start with inserting words into... WebXor encryption is commonly used in several symmetric ciphers (especially AES). A symetric cipher is simply a cipher in which the key is used for xor encryption and decryption process. The XOR operand is so applied to each bit between the text you want to encrypt and the key you'll choose. Examples are better than words, let's take the word "xor".

WebThe XOR operator seems to be a frequently used building block inside many cryptographic primitives. As far as I can see, its most desirable properties seem be that for the XOR of two bits a ⊕ b = c: The information is preserved. Either a or b can be recovered from c and the other bit. The information is hidden.
