TAILIEUCHUNG - Handbook of Applied Cryptography (Discrete Mathematics and Its Applications)

Cryptography, in particular public-key cryptography, has emerged in the last 20 years as an important discipline that is not only the subject of an enormous amount of research, but provides the foundation for information security in many applications. Standards are emerging to meet the demands for cryptographic protection in most areas of data communications. | This is a Chapter from the Handbook of Applied Cryptography by A.
