Hill Cipher Encryption and Decryption | Encryption and Decryption example of hill cipher | Hill Cipher in network secuirty | Hill cipher in cryptography Follow my blog: https://www.chiragbhalodia.com/2021/10/hill-cipher.html There are basically two types of symmetric cipher: Substitution Cipher, Transposition Cipher. Substitution Cipher: A substitution is a technique in which each letter or bit of the plaintext is substituted or replaced by some other letter, number or symbol to produce cipher text. For Example, ABC ⟹ XYZ. Types of Substitution Cipher: Caesar Cipher, Monoalphabetic Cipher, Vigenère Cipher, Playfair Cipher, One time pad cipher (Vernam cipher), Hill Cipher. Transposition Cipher: In transposition technique, there is no replacement of alphabets or numbers occurs instead their positions are changed or reordering of position of plain text is done to produce cipher text. For Example, ABCDE ⟹ BADEC. Types of Transposition Cipher: Rail Fence Cipher, Columnar Transposition Cipher. Hill Cipher is polyalphabetic substitution cipher. This technique was developed by mathematician Laster Hill. Hill cipher based on linear algebra. Input of this technique are keyword and plain text. Keyword is given in matrix form. In this video, I have explained hill cipher encryption and decryption rules with example. Also explained hill cipher example of 2x2 keyword matrix encryption and decryption.
