The word cryptography refers to the science and art of transforming messages to make them secure and immune to attacks. It is basically based on the concept of abstract algebra. Network security is mostly achieved through the use of cryptography. More generally, it is about constructing and analyzing protocols that overcome the influence of adversaries and which are related to various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation. Modern cryptography intersects the disciplines of mathematics, computer science, and electrical engineering.
