WebThe Hill Cipher. The Hill Cipher encrypts blocks of letters simultaneously. For our purposes, we will assume a "block" is a pair of letters, although this encryption scheme is easily generalized to larger blocks of letters. Each possible pair of letters can be associated with a two-dimensional vector made from integers (mod 26) in the usual way ...

In classical cryptography, the Hill cipher is a polygraphic substitution cipher based on linear algebra. Invented by Lester S. Hill in 1929, it was the first polygraphic cipher in which it was practical (though barely) to operate on more than three symbols at once. The following discussion assumes an elementary knowledge of matrices. WebThe Hill Cipher requires a much larger use of mathematics than most other classical ciphers. The processes involved are relatively complex, but there are simply algorithms …
