摘要
感知源数据的可信性是决定应用系统安全和可靠与否的重点因素.提出了一种物联网感知源数据可信性评估模型,从直接信任值、能量信任值、同行推荐信任值和综合信任值等多个维度对感知源数据的可信性进行评估,从而可以有效地识别感知设备的状态.仿真实验表明,模型具有算法简单,能耗低,可以进行边缘计算与动态扩展.
The credibility of source data is a key factor determining the security and reliability of the application system of internet of things(ioT).This paper proposes an evaluation model for IoT source data,which evaluates the credibility of source data from multiple dimensions such as direct trust,energy trust,peer recommendation trust and comprehensive trust.And the state of the sensing devices can be identified effectively,and algorithms of our model are characterized by their simple implementation,low energy consumption,low calculation and dynamic expansion.
