Abstract :
The dissertation reaches the key management mechanism for wireless sensor networks, Key management can be divided into two categories: one is symmetric key management such as the KDC mechanism and random key pre-distribution mechanism, another is asymmetric key management mechanism such as the elliptic curve encryption algorithm. This paper presents a hybrid key management mechanism with double cluster heads based on the advantages and disadvantages of the two managements: a hybrid key management scheme based on the clustering structure, using asymmetric keys to aid in the distribution of symmetric key. This program sets up a spare cluster head within the cluster. Responsible for the safety of the nodes in the cluster. Spare cluster head can effectively prevent the cluster node does not work due to the cluster head invalid. Ensure the stability of each cluster and improve the efficiency of cluster head updates.
