WSN中能支持广播优化的多项式广播认证机制*

针对无线传感器网络中已有的广播认证机制难以支持广播优化、存在延迟等不足,基于虚拟骨干网的思想,构建一个动态阶梯型网络,采用多项式技术,提出了一种能够识别转发节点身份的广播认证机制及其改进方案.该机制计算简单、认证延迟低,而且能够容忍大量的俘获节点；与已有广播认证机制相比,该机制能够支持层次广播优化策略,更适用于大规模网...

Polynomial based broadcast authentication mechanism in support of broadcast optimization for WSN

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.
