Cryptography Decrypted

Cryptography is at the heart of computer security; without it, secure e-commerce and Internet communications would be impossible. Decision-makers and sophisticated computer users need to understand cryptography — but most explanations are highly mathematical and technical. Cryptography Decrypted explains cryptography in "plain English" — and is authoritative and thorough enough to address the needs of professionals. It explains the processes step-by-step, with extensive visuals. The authors present the elements of cryptography systems; public key infrastructure (PKI); and the IPSec standard for virtual private network security; then review real-world systems and their applications. They show how real-world systems are attacked, and how to protect them; introduce essential cryptographic terms; and present the fascinating history of cryptography through sidebars highlighting its important events, people, and breakthroughs. For every decision-maker and computer user who needs to understand cryptography, this book is also ideal for security pros who need to educate management about cryptography.
