BULLETPROOF WIRELESS SECURITY: GSM, UMTS, 802.11, and Ad Hoc Security

It examines wireless cryptographic protocols, types of attacks, weaknesses that attacks exploit and how to defend against them, multilayered-security design and protocols, vulnerabilities, and the role of modulation techniques in security. It uses just enough theory to prepare readers but focuses on practical issues and implementations more than the often-challenging math behind message encoding and decoding for secure links.

Addressing a far different aspect of the engineering-design spectrum, Current Sources & Voltage References by Linden T Harrison thoroughly examines this small but critical area of circuit and IC design. The comprehensive book (Newnes/Elsevier) ISBN-0-7506-7752-X) covers the semiconductor physics, suitable active and passive components and their characteristics, and the circuits that designers build with them. The book dissects and models the various types of FETs, bipolar transistors, and diodes that these circuit functions use and analyzes the resultant performance. These examples use actual devices and model numbers when appropriate. Even if you are more likely to buy than build your own, the book explains what you need to look for when determining the best source or reference for your application.
