Introduction to Cryptography and Network Security

Introduction to Cryptography and Network Security
by Behrouz A. Forouzan
Quote:

This text uses an incremental approach to teaching cryptography and network security.
It assumes no particular mathematical knowledge, such as number theory or abstract
algebra. However, because cryptography and network security cannot be discussed
without some background in these areas of mathematics, these topics are discussed in
Chapters 2, 4, and 9. Readers who are familiar with these areas of mathematics can
ignore these chapters. Chapters 1 through 15 discuss cryptography. Chapters 16
through 18 discuss network security
