摘　　要：为了在无线传感器网络中对广播信息进行有效地认证,使用广播者与各预定接收者的共享密钥计算的广播消息鉴别码,基于Nyberg快速单向累加器的单向性、半交换性和吸收性,构造了一种适用于无线传感器网络的广播认证算法,并从安全性、抗俘获能力和开销等方面对算法进行了详细的分析,分析表明该算法能够在小范围内实现对随机广播信息的即时认证,可满足无线传感器网络对广播认证的基本要求。In order to authenticate the broadcast data in wireless sensor networks efficiently,a broadcast authentication algorithm based on the properties of one-way,quasi-commutative and absorbency in Nyberg’s fasting one-way accumulator was put forward.The MACs computed by hashing the broadcast data with the shared key between the broadcaster and each scheduled receiver were used to be the accumulative items in this algorithm.The detailed analyses in the aspects of the security,anti-captured and costs show that the proposed broadcast authentication algorithm can authenticate the random broadcast data immediately in small area and meet the essential requirements for broadcast authentication in wireless sensor networks.
