Webproblems that are difficult to solve. A problem may be difficult because its solution requires some secret knowledge such as decrypting an encrypted message or signing some digital document. Cryptographic systems are generally classified along three independent dimensions: 1. Type of operations used for transforming plaintext to cipher text. WebThe Hill cipher was the first cipher purely based on mathematics (linear algebra). To encipher a message, first the plaintext is broken into blocks of n letters which are converted to numbers, where A=0, B=1, C=2 ... WebHill ciphers that encipher larger blocks. Notice that the multiplicative cipher is just the 11 × case of the Hill cipher; individual letters are enciphered one at a time. invertible matrices modulo 26 (an invertible matrix is a matrix that has an inverse) can be used to encipher digraphs. 3. 22 × fitting a kitchen units
