Cryptography and Information Security

This well-organized text presents the principles, techniques, design, and implementation of cryptography and information security algorithms, with a perfect balance in the presentation of theoretical and practical aspects. To provide the mathematical background required to understand the principles of cryptography and information security, the text explains all the relevant theorems such as Fermat’s theorem and Euler’s theorem. The book gives a clear analysis of various encryption methods and cipher techniques. In addition, various security measures, for example, firewalls and virtual private network, and web security, are also discussed. Key Features Covers the latest topic of computer forensics and the areas in which they can be applied. Gives algorithms with numerical explanations. Provides a large number of solved problems. The book is intended for the undergraduate and postgraduate students of computer science and engineering (B.Tech./M.Tech.), undergraduate and postgraduate students of computer science (B.Sc./M.Sc. Computer Science), and information technology (B.Sc./M.Sc. IT) and the students of Master of Computer Applications (MCA).
