The research on certificateless hierarchical key management in wireless mesh network

A certificateless hierarchical key management is proposed. The program uses a two-layered structure. The upper clustering head nodes generate the key by using threshold secret sharing, and the lower nodes use certificateless signcryption to generate the keys. The users use their own identify as their public key to reduce the computational complexity without public key certificate. And the program solves the problem of key escrow, realizes the periodic update of the key, which has good scalability and security. It´s proved to be suitable for wireless mesh network.
