Cryptography matrix
Each letter is represented by a number modulo 26. Though this is not an essential feature of the cipher, this simple scheme is often used: To encrypt a message, each block of n letters (considered as an n-component vector) is multiplied by an invertible n × n matrix, against modulus 26. To decrypt the message, each block is multiplied by the inverse of the matrix used for encryption. WebTo generate the ciphertext squares, one would first fill in the spaces in the matrix with the letters of a keyword or phrase (dropping any duplicate letters), then fill the remaining …

http://archive.dimacs.rutgers.edu/drei/1997/classroom/lessons/matrices.html WebThe Rijndael cipher works by first putting the 128-bit block of plain text into a 4-byte-by-4-byte matrix, termed the state, that changes as the algorithm proceeds through its steps. The first step is to convert the plain text block into binary and then put it into a matrix, as shown in Figure 8.3. Figure 8.3. The Rijndael matrix.

WebJun 15, 2024 · In this chapter we outline briefly why quantum computers can make RSA-type cryptosystems obsolete and how lattices can be used in cryptography. We concentrate on perhaps the best-known lattice system, NTRU, and explain how it is used and why attacks on it still seem computationally infeasible. Download chapter PDF.
