摘　　要：提出一个高效的无线传感器网络自适应广播认证机制SABA(Self-adaptive broad-cast authentication mechanism)。SABA将自适应广播认证协议构造过程分为离线协议族选择和在线协议转换规则两部分,通过分析具体应用中的风险增加因素,结合评测备选广播认证协议的安全性和开销,从而选择不同风险情况下效用最优协议作为当前协议。结合一个应用实例说明了SABA的协议构造过程,对自适应广播认证协议的性能评测实验证明了SABA的有效性。Broadcast authentication is a critical security service in Wireless Sensor Networks （WSN）. The broadcast authentication mechanisms that have been proposed in WSN are obvious different in their security strength and overhead, In this paper, an efficient Self-Adaptive Broadcast Authentication （SABA） mechanism in WSN is proposed, which takes the dynamic change of the system risk in application into consideration. The SABA mechanism includes two parts. The off-line part selects a group of protocols for sensor nodes. The on-line part generates protocol transition rules with risk changes. By making use of the protocol utility, derived from the analysis of system risk and the evaluation of protocol security strength and performance, the best protocol under various system risks is selected as the current protocol. A case study is used to demonstrate the construction of a SABA protocol. Analysis and experiments show the efficiency of the SABA.
