Beschreibung

Cryptography, as done in this century, is heavily mathematical. But it also has roots in what is computationally feasible.

This unique textbook text balances the theorems of mathematics against the feasibility of computation. Cryptography is something one actually ¿does¿, not a mathematical game one proves theorems about. There is deep math; there are some theorems that must be proved; and there is a need to recognize the brilliant work done by those who focus on theory. But at the level of an undergraduate course, the emphasis should be first on knowing and understanding the algorithms and how to implement them, and also to be aware that the algorithms must be implemented carefully to avoid the ¿easy¿ ways to break the cryptography. This text covers the algorithmic foundations and is complemented by core mathematics and arithmetic.

Cryptography, as done in this century, is heavily mathematical. But it also has roots in what is computationally feasible.

Über den Autor

Duncan Buell, professor emeritus in the Dept. of Computer Science and Engineering at University of South Carolina, also has 15 years of experience at a research lab doing high-performance computing research in support of the US National Security Agency.

Zusammenfassung

Balances the theorems of mathematics against the feasibility of computation

Covers the algorithmic foundations as well core mathematics and arithmetic

Demonstrates how cryptography is something one actually "does," rather than theorizes about
