Sensor Networking through Intranet and ZigBee

This paper describes a relatively new technology of ZigBee architecture and represents approach to safety and security in sensors networks, namely in ZigBee networks. This contribution describes the security level of sensors network which consists on safe keeping symmetric keys, on the protection of the inbuilt mechanisms and on the proper implementation of encryption mechanisms and their appropriate security policies. The upcoming security encryption services protectes interfaces between various devices, without dividing into levels like in ZigBee stack. This is based on open trust model which allows reusing the same encryption/description keys for communication among simple layers in the stack. It provides safety between two end devices instead of security among end-levels within the frame of one's device. It means that active network key will be used for security broadcast frames on application layer, frame on network layer or orders on MAC layer.
