This comprehensive compendium of the protocols for securing online commerce and payments provides a broad overview of electronic commerce, money, payment systems, and business-to-business commerce, followed by an examination of well-known protocols (SSL, TLS, WTLS, and SET). The book, a valuable resource for students and professionals in the fields of computer science and engineering, IT security, and financial and banking technology, also explores encryption algorithms and methods, EDI, micropayment, and multiple aspects of digital money. Like its predecessor, this edition is a general analysis, with many references provided to more technical resources. It delivers extensive revisions of previous chapters, along with new chapters on electronic commerce in society, new e-commerce systems, and the security of integrated circuit cards.
