The following outline is provided as an overview of and topical guide to cryptography Modern cryptography intersects the disciplines of mathematics, computer science, and engineering Applications of cryptography include atm cards, computer passwords, and electronic commerce. The encyclopedia of cryptography and security is a comprehensive work on cryptography for both information security professionals and experts in the fields of computer science, applied mathematics, engineering, information theory, data encryption, etc [1] it consists of 460 articles in alphabetical order and is available electronically and in print The encyclopedia has a representative.
This technical overview of basic cryptographic components (including extensive diagrams and graphics) explains the evolution of cryptography from the simplest concepts to some modern concepts. Each key pair consists of a public key and a corresponding private key Block ciphers are the elementary building blocks of many cryptographic protocols They are ubiquitous in the storage and exchange of data, where such data is secured and authenticated via encryption. A protocol describes how the algorithms should be used and includes details about data structures and representations, at which point it can be used to implement multiple, interoperable versions of a program. Cryptanalysis has coevolved together with cryptography, and the contest can be traced through the history of cryptography —new ciphers being designed to replace old broken designs, and new cryptanalytic techniques invented to crack the improved schemes.
