In according to elliptic curve cryptography algorithm, the paper put forward a kind of ECC key management scheme based on logic cluster grouping structure for mobile networks.The mobile nodes are divided according to cluster classification, and then, each cluster is logically divided into multiple groups.The communication key is shared within groups and the cluster header is in charge of each group's key on real time.Mobile nodes communicate with cluster header through shared private key within groups so as to ensure about the security of communication.Key exchange protocol based on ECMOV is adopted for all nodes to participate in the group key construction, while a specific period is designed to update the key, which would effectively avoid key leakage.Analysis illustrates that the proposed scheme can effectively reduce the security risks during key exchanges in communication, which is suitable for intelligent mobile terminal platform with limited resource.
