520			_a"Cryptography is a vital technology that underpins the security of information in computer networks. Cryptography is associated with the process of converting ordinary plain text into unintelligible text and vice-versa. It is a method of storing and transmitting data in a particular form so that only those for whom it is intended can read and process it. Cryptography not only protects data from theft or alteration, but can also be used for user authentication. A computer network is an interconnection of various computer systems located at the same or different places. The interconnection is done through a communication link also known as the physical layer of the network and this link is such that it is totally transparent to the users of the network. The transparency of the communication link is brought about by the interfacing software known as protocols which enables a user in one location to freely access a computer system/database/process/software in another location. Cryptography is concerned with the conceptualization, definition and construction of computing systems that address security concerns. The design of cryptographic systems must be based on firm foundations. Securing the Internet presents great challenges and research opportunities. Potential applications such as Internet voting, universally available medical records, and ubiquitous e-commerce are all being hindered because of serious security and privacy concerns. The epidemic of hacker attacks on personal computers and web sites only highlights the inherent vulnerability of the current computer and network infrastructure. This book presents a comprehensive introduction to the role that cryptography plays in providing information security for technologies such as the Internet, mobile phones, payment cards, and wireless local area networks." -- Back cover
