摘要：WSN is the collection of thousands of tiny sensor nodes, which have the capability of sensing, computing and transmitting the information in the network. Due to the low circuit design, it has some resource constraints but efficient to carry the information through wireless communication. But the exchange of information in a secure manner is critical in WSN. There are many techniques developed in recent years for the security purposes, one of the area is the key management. Key management is the challenging issue in sensor networks. In this paper we present the key management techniques for wireless sensor networks and classification has been presented based on the encryption techniques.
