由于大规模无线传感器网络（WSN）将完全集成到互联网中作为物联网（IoT）或网络物理系统（CPS）的核心部分，因此有必要考虑IoT/CPS带来的各种安全挑战，例如恶意攻击的检测。传感器或传感器嵌入物可以使用6LoWPAN协议在彼此之间建立直接通信。信任和声誉模型是物联网/CPS中大型分布式传感器网络抵御恶意节点攻击的重要方法，因为信任建立机制可以促进分布式计算和通信实体之间的协作，便于检测不可信实体，并辅助各种协议的决策过程。本文在深入了解信任建立过程和定量比较信任建立方法的基础上，提出了一种基于行为的信任和信誉模型TRM-IoT，以加强物联网/CPS网络中事物之间的协作。所提出的模型的准确性，鲁棒性和亮度通过广泛的模拟验证。
Since a large scale Wireless Sensor Network (WSN) is to be completely integrated into Internet as a core part of Internet of Things (IoT) or Cyber Physical System (CPS), it is necessary to consider various security challenges that come with IoT/CPS, such as the detection of malicious attacks. Sensors or sensor embedded things may establish direct communication between each other using 6LoWPAN protocol. A trust and reputation model is recognized as an important approach to defend a large distributed sensor networks in IoT/CPS against malicious node attacks, since trust establishment mechanisms can stimulate collaboration among distributed computing and communication entities, facilitate the detection of untrustworthy entities, and assist decision-making process of various protocols. In this paper, based on in-depth understanding of trust establishment process and quantitative comparison among trust establishment methods, we present a trust and reputation model TRM-IoT to enforce the cooperation between things in a network of IoT/CPS based on their behaviors. The accuracy, robustness and lightness of the proposed model is validated through a wide set of simulations.
