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. cynthia cook npWebDecryption involves matrix computations such as matrix inversion, and arithmetic calculations such as modular inverse. To decrypt hill ciphertext, compute the matrix inverse modulo 26 (where 26 is the alphabet length), requiring the matrix to be invertible. cynthia cook smithWebJul 14, 2024 · 1 Answer. Sorted by: 1. Assuming the $\frac {1} {11}$ is correct, you should replace it by $19$, as $11 \times 19 = 209 \equiv 1 \pmod {26}$ so that is the inverse of $11$ modulo $26$. So all entries get multiplied by $19$ so $3$ becomes $3 \times 19 \equiv 7$ etc. Recompute with the new matrix. cynthia coomerWebThis allows us to compute the encryption matrix, and then the decryption matrix. Alternatively, as [ 17 13 7 8] is also invertible (determinant 19) we can find the decryption matrix also from (using A = B C → A − 1 = C − 1 B − 1 etc.) [ a b c d] − 1 = [ 19 7 7 4] [ 17 13 7 8] − 1 as well Share Cite Follow answered May 6, 2024 at 22:35 cynthia cook graphic designer
