The information security of wireless sensor networks is a hot issue in research. This paper examines combining the scheme of the asymmetrical public key system and the threshold key scheme, and proposes a dynamic key management scheme through the second level key matrix of authentication mechanism from the cluster to node. The sink makes use of the lightweight ECC algorithm to preset the public key matrix to the node clusters, then the cluster head conducts the key authentication exchange and

It reduces computing and communication costs, using the preset public key encrypting the data. The clusters adopt bidirectional authentication to promote communication security.
