摘　　要：针对当前无线传感网(WSN)中广播认证方案的端对端时延较长、基于数字签名的广播认证能耗较大的问题,提出一种新的抗拒绝服务(DoS)攻击的广播认证方案,在基于Nyberg快速单向累加器的广播认证的基础上加入信誉机制,引入邻居信誉值和全局信誉值两个参数对节点的信誉值进行全面评估。通过判断全局信誉值的大小来决定是先转发还是先认证,有效地降低了端对端时延,降低了计算和存储能耗,同时增加了对抗DoS攻击的能力。For the end-to-end delay of the current broadcast authentication scheme in Wireless Sensor Network （WSN） is longer, broadcast authentication based on digital signature has a lot of energy consumption, this paper proposed a new broadcast authentication scheme with defending against Deny of Service （DoS） attacks that added the reputation mechanism to the broadcast authentication based on Nyberg＇s fasting one-way accumulator, and introduced two parameters, neighbors reputation values and the global reputation values, to conduct a comprehensive assessment of the nodes. By judging the global reputation value, forward-first or certification-first was determined, which effectively reduced the end-to-end delay, and the computing and storage energy, while increasing the ability of defending against DoS attacks.
