【Abstract】 Wireless sensor network technology, which is the integration of many technologies such as sensors, embedded computing, modern network, wireless communication and distributed information processing, is becoming an important practice area of ubiquitous computing research. Wireless sensor network is composed by a large number of distributed sensor nodes. For many security applications of wireless sensor network, it’s essential to ensure the sensor nodes dependable and credible. Firstly, in this paper, the major security objectives of wireless sensor network are mentioned with information security and nodes security, and the later is more important. Secondly, it is pointed out that sensor nodes are temper-resisted with a security co-processor designed. At the end of the paper, we propose a concise and effective local cluster key pre-distribution algorithm to ensure the trusted mechanism and security of sensor nodes.更多还原
