中文摘要：

针对无线传感器网络路由发现过程中安全性评估问题，提出一种新的自适应威胁模型。该模型通过对传统Dolev．Yao模型进行改进，将攻击分为限定接收传输范围的单个攻击者到不限定任何能力的多个共谋攻击者等九类，在无须任何安全假设的情形下对不同路由发现过程的攻击进行分类安全评估，自适应地确定破坏协议时的攻击强度和破坏协议所需的最小攻击强度，以评估路由发现协议的安全性，进而采取相应的安全措施予以预防。最后以一类无线传感器网络自适应威胁模型为实例，说明该模型的正确性、有效性。

英文摘要：

For the safety evaluation problems in wireless sensor network routing discovery process, this paper put forward a new adaptive threat model. The model improved Dolev-Yao model which attack could be divided into nine categories from limi- ted reception and transmission range of a single attacker to unlimited any ability to multiple collusion attacker. Then it made safety evaluation to different routing discovery process under the situation of without any security assumptions. And it adaptively determined the attack strength and minimum intensity required, to evaluate the security of routing discovery protocol and then took appropriate security measures to preventive. Finally it gave an example of adaptive threat model for wireless sensor net- works to show the correctness and availability of the model.
