Key-management scheme based on identity and cluster layer in wireless sensor network

Key management is one of the key security technology in wireless sensor networks. Key management in wireless sensor networks due to the arrangement of the position, limited the calculation, limited storage capacity, making the design faces many challenges, so the scheme propose a key-management scheme based on identity and cluster layer in wireless sensor network. The scheme use Identity authentication and encryption technology, to carry out the cluster node authentication and key negotiation to resolve the problem within the cluster, namely the establishment of a shared cluster key among cluster members and cluster head. By security analysis, complex analysis, performance analysis, and compared with other programs, programs can ensure full connectivity within a cluster, the new node and easy to join, meet the requirements of wireless sensor networks.
