WebNov 2, 2024 · In the Hill cipher, there is an invertible matrix for the key K of size n × n, and the plaintexts m i 's are row vectors of size n. The encryption of a block m is performed by c = m K and the encryption of the message can be considered mathematically take c = m K. For decryption, multiply both sides with K − 1 and get c K − 1 = m K K − 1 ... WebThe hill cipher is a method of encryption invented in 1929 by Lester S. Hill. When they were invented they were the most practical polygraphic substitution cipher because the process is simple and can be used on more than three symbols, which was a …
