Internet of things security evaluation mechanism based on meta attribute fluctuation

Abstract

In the field of Internet of Things (IoT), terminal security has always been an extremely important independent research topic. In the terminal security research, in addition to the security enhancement of terminal entities, the security status evaluation of terminal security has also become an independent subset of the security research in the IoT field. However, it should also be noted that the security attributes of IoT terminals can include many aspects, so judging the security of IoT terminals based on the overall security form is not enough for the security of terminal entities. This paper introduces the concept of volatility from the overall situation assessment to the meta attributes that constitute the overall security situation, and preliminarily realizes the construction of a concise model based on historical data to judge the meta attributes that may affect the overall security in the future. At the same time, a concise verification system is built based on the application scenario of the power IoT terminals currently under research to preliminarily realize trend prediction, further expand the trust evaluation of IoT terminals, and clarify the direction of further research.
