The continued growth of e-commerce mandates the emergence of new technical standards and methods that will securely integrate online activities with pre-existing infrastructures, laws and processes. Protocols for Secure Electronic Commerce, Second Edition addresses the security portion of this challenge. It is a full compendium of the protocols for securing online commerce and payments, serving as an invaluable resource for students and professionals in the fields of computer science and engineering, IT security, and financial and banking technology. The initial sections provide 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 also explores encryption algorithms and methods, EDI, micropayment, and multiple aspects of digital money. Like its predecessor, this edition is a general analysis that provides many references 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.
