摘　　要：为了实现对操作系统和应用程序实时状态的可信度量,针对无线Mesh网络的多跳特性,将可信度量分为启动状态度量和运行状态度量两步来实现.启动状态度量使用存储在平台配置寄存器中的Hash值来进行运算评估,而运行状态度量则使用灰色关联分析方法来度量评估当前运行程序的信任度.最后通过仿真实验分析,证明了在无线Mesh网络中该可信度量模型性能良好,可以有效检测出网络中状态不可信的节点,同时存在低于10%的误检率.In order to realize trusted measurement of the running states of operating system and application programming,considering multi-hop feature of wireless Mesh network,two steps were carried out to evaluate the system′s trust:starting states and runtime states.The values stored in PCR(platform configuration registers)were used to measure and evaluate starting states,and grey relevance analysis method to evaluate runtime states.And then the proposed trust evaluation mechanism was implemented in trusted network connections of wireless Mesh networks.Moreover,in network simulations,untrusted nodes can be detected effectively and false detection rate is less than 10%,which shows the performance is good.
