WebSome important concepts are used throughout: Matrix Multiplication; Modular Inverses; Determinants of Matrices; Matrix Adjugates (for finding inverses). Encryption To encrypt a message using the Hill Cipher we must first turn our keyword into a key matrix (a 2 x 2 matrix for working with digraphs, a 3 x 3 matrix for working with trigraphs, etc). WebCryptography has played an important role in information and communication security for thousand years. It was first invented due to the need to maintain the secrecy of information transmitted over public lines. ...
