ABSTRACT
This chapter analyzes the security issues related to wireless personal area mesh networks. It investigates how Bluetooth and ZigBee have implemented their security architecture. It is clear that providing security for both types of networks is essential as wireless links are easy to eavesdrop undetected. A security architecture is a collection of building blocks and security policies that make up a complete security solution. The major constraint when designing a security architecture for mobile devices with limited resources is available energy and speed of the CPU. The ZigBee security architecture provides nodes with a mechanism to establish keys with other nodes in the network. ZigBee is a set of communication protocols that operate on the application and network layer. The security control field in the header specifies which security level is used to secure the frame. The commercial mode of the trust center is designed for high-security commercial applications.
