This book presents modern concepts of computer security. It introduces the basic mathematical background necessary to follow computer security concepts. Modern developments in cryptography are examined, starting from private-key and public-key encryption, going through hashing, digital signatures, authentication, secret sharing, group-oriented cryptography, pseudorandomness, key establishment protocols, zero-knowledge protocols, and identification, and finishing with an introduction to modern e-bussiness systems based on digital cash. Intrusion detection and access control provide examples of security systems implemented as a part of operating system. Database and network security is also discussed.This textbook is developed out of classes given by the authors at several universities in Australia over a period of a decade, and will serve as a reference book for professionals in computer security. The presentation is selfcontained. Numerous illustrations, examples, exercises, and a comprehensive subject index support the reader in accessing the material.

From the reviews: "The goal of the book is to present the basic concepts in computer and network security. … It has 18 chapters, each … concluding with a set of exercises and problems. … the book overviews the most important topics of cryptography and some topics on computer security. It may be used for self-study, as well as a text for undergraduate and postgraduate courses." (Lenka Fibikova, Zentralblatt MATH, Issue 1011, 2003)

Introduces all basic mathematical concepts necessary for further study of secure systems The concepts are presented clearly and illustrated by numerous examples The book can also be used as a reference to quickly learn about terms used in Computer Security Includes supplementary material: sn.pub/extras
