Security in Embedded Devices

The foundation of embedded security design is presented in this overview, enhancing understanding for security engineers and designers alike. Case studies illustrate the concepts behind topics like contactless smartcards, and PDA and satellite security.

Although security is prevalent in PCs, wireless communications and other systems today, it is expected to become increasingly important and widespread in many embedded devices. For some time, typical embedded system designers have been dealing with tremendous challenges in performance, power, price and reliability. However now they must additionally deal with definition of security requirements, security design and implementation. Given the limited number of security engineers in the market, large background of cryptography with which these standards are based upon, and difficulty of ensuring the implementation will also be secure from attacks, security design remains a challenge. This book provides the foundations for understanding embedded security design, outlining various aspects of security in devices ranging from typical wireless devices such as PDAs through to contactless smartcards to satellites.

Provides must-have content for both security engineers and embedded systems designers Describes numerous case studies, including contactless smartcards, PDA security, and satellite security, illustrating various aspects of secure, embedded design Covers hardware architecture, software and circuit design Shows readers how to attack an embedded system and how to embed countermeasures to resist attack--readers are shown that understanding attacks is crucial to implementing security in embedded systems Includes supplementary material: sn.pub/extras
