Digital Encoding for Secure Data Communications

Abstract

This thesis is concerned with the use of the digital computer to realize cryptography. Three cryptographic systems: simple substitution, pseudo-random cipher (polyalphabetic cipher), and data-keyed cipher, are designed, implemented through computer programming, and evaluated. A suitable cyclic error correcting code is designed to encode these systems for transmission. The code is tested by simulating a noisy channel.
