Introduction to Modern Cryptography and Network Security

Description

Modern cryptography is the corner stone of computer and communications security. Its foundation is based on various aspects concepts of mathematics such as number theory, computational- complexity theory and probability theory. The study of cryptosystem can be subdivided into two branches: 1. Cryptography, 2. Cryptoanalysis. Cryptography deals with the actual securing of digital data. Cryptography is the art and science of Making a cryptosystem that is capable of providing information security and the era and science of breaking the cipher text is known as cryptanalysis. The authors introduce the core principles of modern cryptography with an emphasis on formal definitions, clear assumptions, and rigorous proofs of security.
