The surefire way to get ahead is to think ahead. So, while you are working in the here-and-now (whether revamping a client’s Web site or upgrading the client’s supply chain), there’s no time like the present to examine technologies that haven’t been widely adopted but could have a huge impact on enterprises during the next 10 years. Take wireless data networks, for instance: Anywhere, anytime access to corporate data from your...

Wireless securrity and privacy
This book provides wireless and security professionals with a foundation on which to design secure wireless systems. Most security problems are handled reactively rather than proactively; this does not have to be the case for wireless security. In the past decade, advances in software development have outpaced advances in software security.

Radio frequency integrated circuit design
Radio frequency integrated circuit (RFIC) design is an exciting area for research or product development. Technologies are constantly being improved, and as they are, circuits formerly implemented as discrete solutions can now be integrated onto a single chip. In addition to widely used applications such as cordless phones and cell phones, new applications continue to emerge. Examples of new products requiring RFICs are wireless local-area...

A Brief History of Security “Well, I never heard it before,” said the Mock Turtle, “but it sounds uncommon nonsense.” —Lewis Carroll, Alice in Wonderland. Secret communication achieved by hiding the existence of a message is known as steganography. The word is derived from the Greek word “steganos,” meaning cov- ered and “graphin” meaning to write.
