Research on IoT devices key protection mechanism based on PUF model

在各类型设备大量接入实验室以及物联网技术普及的背景下,数据出力、传输、分析以及存储过程中会出现数据安全问题,为此设计一种基于物理不可克隆函数和分布式云计算相配合的密钥安全保护机制。利用物理不可克隆函数的不被复制性和不被克隆性,对局域设备物联网环境下的设备接入数据、安全访问数据以及计算数据进行统一出力。与此同时,通过引入分布式云计算技术对物联网设备数据进行分级管理、分级传输以及加密存储,既保证了物联网自身的安全,也为数据安全问题提供了解决方案。以传输过程中的数据集为样本进行对比实验测试,结果表明,相比于其他安全机制,文中所提机制的安全性可达87%以上,能够为高校实验室中的物联网设备提供数据处理与传输的安全保障。

In the context of a large number of different types of devices accessing laboratories and the popularization of Internet of Things(IoT)technology,data security problems will occur in the process of data output,transmission,analysis and storage.Therefore,a key security protection mechanism based on the combination of physical unclonable function(PUF)and distributed cloud computing is designed.By utilizing the non replicability and non cloning properties of PUF,unified output is realized for the device access data,secure access data,and computation data in the local device IoT environment.At the same time,by introducing distributed cloud computing technology,hierarchical management,hierarchical transmission,and encrypted storage of IoT device data are carried out,which not only ensures the security of the IoT itself,but also provides a solution for data security issues.The comparative experimental tests are conducted by using data sets in the transmission process as samples.The results show that,in comparison with other security mechanisms,the security of the proposed mechanism can reach more than 87%,which can provide security protection for data processing and transmission of IoT devices in university laboratories.
