writes "When Bruce Schneier first published Applied Cryptography in 1994, it was a watershed event, given that is was one of the first comprehensive texts on the topic that existed outside of the military. In the nearly 20 years since the book came out, a lot has changed in the world of encryption and cryptography. A number of books have been written to fill that gap and Everyday Cryptography: Fundamental Principles and Applications is one of them. While the title may give the impression that this is an introductory text; that is not the case. Author Keith Martin is the director of the information security group at Royal Holloway, a division of the University of London, and the book is meant for information security professionals in addition to being used as a main reference for a principles of cryptography course. The book is also a great reference for those studying for the CISSP exam."

An anonymous reader writes in a story about a neat potential use for spider silk. "Many people have heard that spider silk is a sort of supermaterial: stronger than steel, tougher than Kevlar, and yet incredibly malleable and flexible. But the silk has other properties that make it ideal for use in electronic devices. Light can travel through a silk strand as easily as it does through a fiber optic cable.
'When we first tested spider silk, we didn’t know what to expect,' said physicist Nolwenn Huby of the Institut de Physique de Rennes in France. 'We thought, "Why not try this as an optical fiber to propagate light?'" Huby and her team were able to transmit laser light down a short strand of the silk on an integrated circuit chip. The silk worked much like glass fiber optic cables, meaning it could carry information for electronic devices, though it had about four orders of magnitude more loss than the glass. Huby said that with a coating and further development, the silk could one day have better transmission capabilities. She will present her results at this year’s Frontiers in Optics conference, Oct. 14 to 18 in Rochester, New York.Read Replies (0)
