This is the symmetrical key Y", where X is a randomly generated identifier, and Y is a randomly generated secret key meant for symmetrical encryption. Hence, both X and Y are unique to each message. All the messages are encrypted in a way such that a user may conduct a brute force attack on each message with some difficulty.
In cryptography, confusion and diffusion are two properties of a secure cipher identified by Claude Shannon in his 1945 classified report A Mathematical Theory of Cryptography. [1] These properties, when present, work together to thwart the application of statistics , and other methods of cryptanalysis .
In cryptography, an SP-network, or substitution–permutation network (SPN), is a series of linked mathematical operations used in block cipher algorithms such as AES (Rijndael), 3-Way, Kalyna, Kuznyechik, PRESENT, SAFER, SHARK, and Square.
CRYPTOGRAPHY PUZZLES Celebrity Cipher "We need storytelling. Otherwise life just goes on and on, like the number pi." − Taiwanese filmmaker Ang Lee (Distributed by Andrews McMeel)
In cryptography, an S-box (substitution-box) is a basic component of symmetric key algorithms which performs substitution. In block ciphers, they are typically used to obscure the relationship between the key and the ciphertext, thus ensuring Shannon's property of confusion. Mathematically, an S-box is a nonlinear [1] vectorial Boolean function ...
Diffusion leads to an elimination of a statistical relation between changes in single plaintext bits and changes in single ciphertext bits. If you change a plaintext bits, a cipher with good diffusion should lead to a 50 pc chance for _any_ ciphertext bit to change. Confusion, on the other hand, does the same for the key<->ciphertext relation.
