The first step is to create a matrix using the keyword (since the keyword is shorter than 9 letters, just start the alphabet again until the matrix is full). Now we need to find the multiplicative inverse of the determinant ...

WebThe Hill Cipher, created by Lester Hill in 1929, is a cipher that has not been successfully decrypted in a ciphertext only attack [3]. Numerous attempts have been made over the years by various cryptanalysts, but to date no complete successes have been achieved for all block sizes of the key matrix when analyzing ciphertext only.

Patented mechanism works on 6×6 sized keys. This increases key space to 26 36. This is very large even for today computation power. Increasing the size of key matrix makes the cipher much ...
WebMar 5, 2010 · Hill Cipher Each letter is first encoded as a number. Often the simplest scheme is used: A = 0, B =1, ..., Z=25, but this is not an essential feature of the cipher. The encryption takes m successive plaintext letter and substitutes them for m ciphertext letters. WebDec 3, 2001 · If we would do a Hill 3-cipher, we would group the letters in groups of 3 letters and use a 3 x 3 transformation matrix, but in this example we're using a Hill 2-cipher. For a …
