WebDec 17, 2016 · Cryptanalysis of Hill Cipher. If you need a reminder on how the Hill Cipher works click here. The first thing to note is that when encoding in Hill Cipher each row of the key matrix encodes to 1 letter independently of the rest of the key matrix. Notice how the top row of the far left matrix is only involved in the top cell of the ciphertext ... Web1. I'm new to cryptography and I cannot seem to get my head around this problem: The problem says that the Hill Cipher using the below 2 x 2 key matrix (K) was used to produce the ciphered text "KCFL". K = (3 5) (2 3) It then asks to use the Hill Cipher to show the calculations and the plain text when I decipher the same encrypted message "KCFL ...

[ 2 − 7 − 3 1] by 15 to get the inverse matrix we're looking for (of course all modulo 26) and we get. [ 4 18 7 15] and now you can do the multiplication from the first equation modulo 26: [ − 9 − 2 − 2 9] [ 4 18 7 15] to find the encryption matrix E.
