An opposite site that intercepts n plaintext/ciphertext character pairs can set up a linear system that can be easily solved; if this will happen then this system is undefined, it is the only way is to add a few more plaintexts/ciphertext pairs. Hill Cipher Implementation > C Program Cryptography and System Security. The only problem is that the final cipher text shows only the last shifted character, not an entire string with all the shifted characters.

This technique is an example of Polyalphabetic Substitution technique which uses 26 Caesar ciphers make up the mono-alphabetic substitution rules which follow a count shifting mechanism from 0 to 25. Imagined by Lester S. Hill in 1929. and in this manner got its name. Algoritma Hill Cipher menggunakan matriks invertible berukuran n x n sebagai kunci untuk melakukan enkripsi dan dekripsi pada chipertext. That implement different classical cryptosystem. Hill Cipher which is a polyalphabe tic cipher can be categorized as a block cipher because the text to be processed will be divided into blocks of a certain size.
