Key Pre-distribution using the Quorum System in Wireless Sensor Networks

摘要: The security feature is essential in wireless sensor network such as intrusion detection or obstacle observation. Sensor nodes must have shared secret between to support privacy. Many methods which provide key pre-distribution need too many keys poor security. To solve this problem, probabilistic proposed. This method needs a few and use share keys. However, does not guarantee sharing nodes, neighbor nay communicate each other. It leads waste of resource inefficient routing, extra routing protocol. In paper, we propose new distribution using quorum system nodes. We also extension the fewer when node deployment knowledge well known
