Cryptography with matrices
WebDec 3, 2001 · Cryptography is the study of encoding and decoding secret messages. In the language of cryptography, codes are called the ciphers, uncoded messages are called plaintext, and coded messages are called ciphertext. Cryptography has for long been an important issue in the realm of computers. WebMatrices, Cryptography, Cramer's Rule, and More! How do you write an encrypted message? This is the most simple form of Cryptography with matrices. One can add a coding matrix for the coding matrix, and so on. With the more levels added, the more secure the message will be. How do you decode an encrypted message?

WebFirst, compute the determinant of the matrix, detA. If detA is coprime to p, then you can be sure that A is invertible modp. Find the inverse of detA modulo p. This matrix we denote by (detA) −1 and will be the unique integer between 0 and p which satisfie (detA) × (detA) −1 ≡ 1 mod p. Next, compute the matrix of cofactors of A, call this B. WebThe matrix used for encryption is the cipher key, and it should be chosen randomly from the set of invertible n× nmatrices (modulo26). The cipher can, of course, be adapted to an alphabet with any number of letters; all arithmetic just needs to be done modulo the number of letters instead of modulo 26.
