从传感器行为的空间相关性和时间相关性入手。提出一种基于相似度的以局部检测为主的分布式传感器行为信任认证机制。
Considering that in many cases, a sensor behaviour is both spatially and temporally correlated, proposes a distributed and localized behaviour trust mechanism based on similarity.
信任机制是解决这些问题的有效手段，为保证分布式环境的安全提供了新的思路和方法，已经成为当前的一个研究热点。
Trust mechanism is an effective way to address these issues. It provides new thinking and methods to ensure the security of distributed environments and has become a current research hotspot.
系统中采用了信任链机制、基于角色的访问控制模型、两级日志、可信认证等技术，同时给出了可信在分布式计算机系统中的实现技术和途径。
In this system, many new techniques are adopted, for example, mechanism of the chain of trust, role-based access control model, two-level of logs, trusted authorization and so on.
