%X In order to resolve the problem of pairwise key pre-configured scheme in wireless sensor network,the introduction of a temporary initial key and chaotic encryption arithmetic, this paper put forward an improved wireless sensor network key pre-configured scheme. The program enabled encryption key random change, and could update the key,effectively enhance the capacity of the network of anti-decipher,the realization of the symmetric and asymmetric key system integration. The analysis shows that the scheme has a certain advantage in terms of network security, key connectivity, memory requirements and computation of key agreement, etc. It has implemented by easy software on Mica2 node.
