摘　　要：针对无线传感器网络中(WSNs)已有的广播认证机制难以支持广播优化等问题,提出1种能够识别转发节点身份的认证机制:通过构造认证函数、预置密钥,生成、发送并验证广播数据包;然后进行安全性分析,并与已有机制进行安全性和存储开销的对比,具有高效,能抵抗重放攻击,能够容忍大量的俘获节点的特点,而且支持广播优化策略,适用于大规模无线网络。实验结果表明,该机制在大规模网络应用中能提高签名认证速度,减少能量消耗。Aiming at the problem that it is difficult to support broadcast optimization for existing broadcast authentication mechanisms in wireless sensor networks(WSNs),the paper proposed an authentication mechanism that can identify the forwarding nodes:the broadcast packets were generated,sent and validated by constructing authentication functions and presetting keys;and the security was analyzed;then,the mechanism was compared with existing mechanisms for the security and storage overhead,indicating that it has the characteristics of high efficiency,resistance to replay attacks,and tolerance of a large number of capture nodes,and supports broadcast optimization strategies,suitable for large-scale wireless networks.Experimental result showed that the proposed scheme could increase the speed of signature verification and reduce energy consumption in large-scale network applications.
