Complex Orthogonal Space-Time Processing in Wireless Communications incorporates orthogonal space-time processing using STBCs in MIMO wireless communication systems. Complex Orthogonal STBCs (CO STBCs) are given emphasis because they can be used for PSK/QAM modulation schemes and are more practical than real STBCs.

The overall coverage provides general knowledge about space-time processing and its applications for broad audiences. It also includes the most up-to-date review of the literature on space-time processing in general, and space-time block processing in particular. The authors also examine open issues and problems for future research in this area.

Orthogonal designs have proved fundamental to constructing code division multiple antenna systems for more efficient mobile communications. Starting with basic theory, this book develops the algebra and combinatorics to create new communications modes. Intended primarily for researchers, it is also useful for graduate students wanting to understand some of the current communications coding theories.

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.

The third International Workshop on Information Security was held at the U- versity of Wollongong, Australia. The conference was sponsored by the Centre for Computer Security Research, University of Wollongong. The main themes of the conference were the newly emerging issues of Information Security. Mul- media copyright protection and security aspects of e-commerce were two topics that clearly re?ect the focus of the conference. Protection of the copyright of electronic documents seems to be driven by strong practical demand from the industry for new, e cient and secure solutions. Although e-commerce is already booming, it has not reached its full potential in terms of new, e cient and secure e-commerce protocols with added properties. There were 63 papers submitted to the conference. The program committee accepted 23. Of those accepted, six papers were from Australia, ve from Japan, two each from Spain, Germany and the USA, and one each from Finland and Sweden. Four papers were co-authored by international teams from Canada and China, Korea and Australia, Taiwan and Australia, and Belgium, France and Germany, respectively. Final versions of the accepted papers were gathered using computing and other resources of the Institute of Mathematics, Polish Academy of Sciences, Warsaw, Poland. We are especially grateful to Jerzy Urbanowicz and Andrzej Pokrzywa for their help during preparation of the proceedings.
