This paper proposes a pairwise key management scheme based on elliptic curve cryptosystem for WSNs,introduces the certificate service which can realize the distribution,update and revocation of the key and key generation when new nodes join.The analysis result shows that compared with the existing key updating schemes for WSNs,this scheme based on elliptic curve cryptosystem can effectively reduce the storage space of the keys,adds the confidentiality and authentication function in key updating stage and increases the difficulty of the network attack.
