This text covers the
fundamentals of cryptography, which is concerned with
methods of security in the storage and transportation of
information.
Computers are now found in
every layer of society, and information is being
communicated and processed automatically on a large scale.
Examples include medical and financial files, automatic
banking, video-phones, pay-tv, facsimiles, tele-shopping and
global computer networks. In all these cases there is a
growing need for the protection of information to safeguard
economic interests, to prevent fraud and to ensure privacy.
In this book, the fundamentals of secure storage and
transportation of information are described. Among other
things, attention is given to symmetric (DES) and asymmetric
(RSA) cryptographic algorithms, which are suitable for data
security, to methods for authentication, data integrity and
digital signatures, key management and to network
aspects.
The book will be of value to
advanced students and researchers involved in data
protection and information processing, including electrical
engineers, mathematicians, business managers, system
designers, application programmers, information analysts and
security officers.

On all levels of society
systems have been introduced that deal with the
transmission, storage and processing of information. We live
in what is usually called the information society.
Information hasb ecome a key word in our society. It is not
surprising therefore that from all sorts of quarters
interest has been shown in what information really is and
consequently in acquiring a better knowledge as to how
information can be dealt with as efficiently as
possible.
Information theory is
characterized by a quantitative approach to the notion of
information. By means of the introduction of measuresfor
information answers will be sought to such questions as: How
to transmit and store information as compactly as possible?
What is the maximum quantity of information that can be
transmitted through a channel? How can security best be
arranged? Etcetera. Crucial questions that enable us to
enhance the performance and to grasp the limits of our
information systems.
Contents
This
textbook has the purpose of introducing a number of basic
notions of information theory and clarifying them by showing
their significance in present applications. Matters that
will be described are, among others: Shannon's information
measure, discrete and continuous information sources and
information channels with or without memory, source and
channel decoding, rate distortion theory, error-correcting
codes and the information theoretical approach tocryptology.
Special attention has been paid to multiterminal or -network
information theory; an area with still lots of
unansweredquestions, but which is of great significance
because most of our information is transmitted by
networks.
All chapters are concluded
with questions and worked solutions.That makes the book
suitable for self study.
