%X Due to the existing broadcast authentication mechanism in WSN are hardly support broadcast optimization, and introduce delay in authentication. Based on the idea of a virtual backbone network,this thesis proposed a broadcast authentication mechanism which could identify the forwarding node, adopting the polynomial technique, built on a dynamic hierarchical network.Then the thesis brought forward some improvements. Those mechanisms were lightweight in terms of computation, allowed immediate authentication, and could tolerate a large number of node compromises. Compared with the existing schemes, the broadcast authentication mechanism can support broadcast optimization, and more suitable for the large-scale network.
