Question: 3 hill cipher a 4 points how many different matrices...

Question details

3. Hill cipher (a.) (4 points) How many different matrices Ad (b.) (4 points) Suppose we know that the plaintext ABLE is encrypted as ZXTOQ (c.) (7 points) Use the following letter-to-number conversion table d are there in modulo 2? How many of them are invertible? using Hill cipher in modulo 26 with a matrix A. Find A. () | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | A | B | C | D | E İFLGIH| 1 0 1 2 3 45 67 89 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 3031 32 33 34 35 36 to decrypt the following message knowing that it is the Hill cipher in modulo 37 and key matrix 7G
