This revised third edition presents the subject with the help of learning objectives (LO) guided by Bloom's Taxonomy and supports outcome-based learning. It discusses concepts from elementary to advanced levels with focus on mathematical preliminaries. Numerous solved examples, algorithms, illustrations & usage of fictitious characters make the text interesting and simple to read.
Salient Dedicated section on Elementary Mathematics Pseudo codes used to illustrate implementation of algorithm Includes new topics on Shannon's theory and Perfect Secrecy, Unicity Distance and Redundancy of Language
Interesting elements introduced through QR codes - Solutions to select chapter-end problems (End of every chapter) - 19 Proofs of theorems (Appendix Q) - Secured Electronic Transaction (Appendix R)
A good introductory book on cryptography and network security related topics. This was the assigned textbook for a class that I took on Cryptography and so I may have chosen a different book if I had the choice. That said, I did learn alot from the textbook and would recommend it as a useful resource.
