You assume that T H → R H and H E → N I under the Hill cipher. The determinant of [ 19 7 7 4] is 19 ⋅ 4 − 7 ⋅ 7 = 1 ( mod 26), so the inverse exists and equals (using − 7 = 19 ( mod 26)) This allows us to compute the encryption matrix, and then the decryption matrix. green pass toscana

WebMar 21, 2024 · (Take a look at C# example here) We can split the Galois multiplication into two steps. First we take two values written in binary 0 x 53 ⋅ 0 x C A = 01010011 b ⋅ 11001010 b and we multiply them the same way as we would multiply two polynomials, keeping in mind that addition here is a XOR operation. WebThe matrix has to go to the left of the column so that matrix multiplication is defined.
