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.
当前对等网络研究的重点是基于分布式哈希表的资源定位问题，以及基于节点间信任机制的交互安全问题。
Currently, the research of p2p is focused on resources location based on distributed hash table and transaction security based on trust mechanism between peers.
在P2P分布式文件系统中，一般不存在完全意义上的中心服务器，其信任机制的建立依靠的是非中心化的信任管理。
In P2P distributed file system, there are not any central severs with complete founctions. That means the construction of trust system depends on non-central or distributed methods.
当前分布式系统中的负载均衡的预测都是基于对预测结果完全信任的机制，但是这种信任会有一定的风险，进而影响系统的效率。
Load balancing prediction in distributed system is based on full trust in prediction currently. However such trust may risk wrong prediction and degrade the systems efficiency.
