520			_aCryptography and Network Security is a sincere effort to present the complex concepts of Cryptography in a manner that can be easily grasped by students of Computer Science. The mathematical foundations of Cryptography like Field, Discrete Logarithms, etc. have been comprehensively covered in a separate chapter, giving proofs of various theorems in a simple manner. The Cryptographic schemes have been organized under different chapters like Classical Cipher schemes, modern Symmetric Cipher schemes (including advanced Encryption Standard) and Public-Key encryption schemes like RSA, Diffie-Hellman and E-Gamal etc. The cutting-edge technology Elliptic Curve Cryptography (ECC) has been adequately covered both for Data Confidentiality and Authentication with ample examples. The concepts of Authentication like Message Digests, Secure Hashing and Digital Signatures are comprehensively covered in a separate chapter. The security services like KERBEROS, IPSec, Secure Socket Layer/Transport Layer Security, Secure Electronic Transaction (SET), Pretty Good Privacy and S/MIME are adequately covered. It is firmly believed that the book will of great help to students of cryptography and network security. The book, perhaps the first of its kind, in terms of its concept and content, is designed to be used as a primer, a workbook, a refresher capsule and a reference book, all rolled into one, depending on the needs and skills of the user.
