tailieunhanh - Cryptography and Network Security Principles and Practices, Fourth Edition

William Stallings' Cryptography and Network Security: Principles and Practice, 5e is a practical survey of cryptography and network security with unmatched support for instructors and students. In this age of universal electronic connectivity, viruses and hackers, electronic eavesdropping, and electronic fraud, security is paramount. This text provides a practical survey of both the principles and practice of cryptography and network security. First, the basic issues to be addressed by a network security capability are explored through a tutorial and survey of cryptography and network security technology. Then, the practice of network security is explored via practical applications that have been implemented. | Table of Contents Cryptography and Network Security Principles and Practices Fourth Edition. 1 Table of Contents Copyright.
