INTRODUCTION TO INFORMATION THEORY, CODES & CRYPTOGRAPHY N. Alexandris - B. Chryssikopoulos

Untouched and unused.

Description:
The security of information is today an important element of the smooth functioning of modern society. Issues concerning the protection of systems and services constantly arise, and addressing them is more than imperative.<br /> Various sciences come with their methods and techniques to assist today's societies in facing risks such as eavesdropping, data tampering, and privacy violations. However, the most crucial roles among them are considered to be held by Information Theory, Coding Theory, and Cryptography.<br /> This book attempts to introduce the reader to the basic concepts, their methods, and the applications of these sciences. In the fifteen chapters of the book, the following are presented: necessary mathematical background, entropy, channels, codes, error detection and correction codes, variable-length codes, algebraic codes, classical cryptography, the algorithms DES, AES, stream and public key, hash functions, digital signatures, cryptographic protocols, as well as some source codes of important algorithms.
