Book Description
Knowledge of number theory and abstract algebra are pre-requisitesfor any engineer designing a secure internet-based system. However, most of the books currently available on the subject areaimed at practitioners who just want to know how the various toolsavailable on the market work and what level of security theyimpart. These books traditionally deal with the science andmathematics only in so far as they are necessary to understand howthe tools work. Internet Security differs by its assertion that cryptography is thesingle most important technology for securing the Internet. Toquote one reviewer "if every one of your communication partnerswere using a secure system based on encryption, viruses, worms andhackers would have a very hard time". This scenario does notreflect the reality of the Internet world as it currently stands.However, with security issues becoming more and more importantinternationally, engineers of the future will be required to designtougher, safer systems. Internet Security: * Offers an in-depth introduction to the relevant cryptographicprinciples, algorithms protocols - the nuts and bolts of creating asecure network * Links cryptographic principles to the technologies in use on theInternet, eg. PGP, S/MIME, IPsec, SSL TLS, Firewalls and SET(protecting credit card transactions) * Provides state-of-the-art analysis of the latest IETF standardsplus summaries and explanations of RFC documents * Authored by a recognised expert in security Internet Security is the definitive text for graduate students onsecurity and cryptography courses, and researchers in security andcryptography areas. It will prove to be invaluable to professionalsengaged in the long-term development of secure systems.

Book Description
Spread spectrum multiple access communication, known commercially as CDMA (Code Division Multiple Access), is a driving technology behind the rapidly advancing personal communications industry. Its greater bandwidth efficiency and multiple access capabilities make it the leading technology for relieving spectrum congestion caused by the explosion in popularity of cellular mobile and fixed wireless telephones and wireless data terminals. Written by a leader in the creation of CDMA and an internationally recognized authority on wireless digital communication, this book gives you the technical information you need. It presents the fundamentals of digital communications and covers all aspects of commercial direct-sequence spread spectrum technology, incorporating both physical-level principles and network concepts. You will find detailed information on signal generation, synchronization, modulation, and coding of direct-sequence spread spectrum signals. In addition, the book shows how these physical layer functions relate to link and network properties involving cellular coverage, Erlang capacity, and network control. With this book, you will attain a deeper understanding of personal communications system concepts and will be better equipped to develop systems and products at the forefront of the personal wireless communications market.

Book Description
One hundred years ago, the notion of transmitting information without the use of wires must have seemed like magic. In 1896, the first patent for wireless communication was granted to Marchese Guglielmo Marconi. Since then the field of wireless communications which includes cellular systems has taken various forms of development. It basically evolved through three Eras. The Pioneer Era over the period of 1860-1921, the Precellular Era over 1921-1980 and the Cellular Era after 1980 and beyond. The first generation cellular era started with the Analog Systems and evolved in the digital domain utilizing Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA), thus comprising the Second Generation Mobile Systems. The first generation RF cellular communications systems deployed in the early to mid 1980's had air interfaces comprised of analog technology. Among them were AMPS (Advanced Mobile Phone System), NMT (Nordic Mobile Telephone), and TACS (Total Access Communications System). These were designed for use in a specific geographic area and not intended to be deployed in other areas. There was not much commonality beyond using the same air interface technology and same modulation. The air interface technology was Frequency Division Multiple Access (FDMA) and the modulation was analog FM, but with different deviations and channel spacings. The frequency bands, air interface protocols, number of channels, and data rates were different. In general, these systems provided local and national coverage.
