ICSA guide to cryptography

The key to computer security. The widely accepted answer to all computer security questions is to use cryptography, but that hardly settles the issue. The ICSE Guide to Cryptography takes care of that. Written by an expert in cryptography, and backed by the leading professional cryptographic organization, this highly informative book tackles the key cryptographic issues with a special focus on current technical problems. Integrating the rich history of classical cryptography with modern public key cryptosystems, this priceless guide is an authoritative source of information on processes, products, management, implementation, and product certification. For anyone who has ever been fascinated by "secret codes," but especially for information technology workers and managers directly concerned with secure computing, the ICSA Guide to Cryptography is the right book, at the right time. Hands-on Help with Today's Challenges. Protecting digital cash and e-commerce. Proper implementation of cryptography onto computer systems. Using cryptanalysis to penetrate advanced computer networks. Cost-effective protection for communications; linking different cryptographic technologies; guarding business data and systems; PLUS: contributions from widely known experts.
