Analytic Hierarchy Process Based Risk Assessment Method for Internet of Things

Abstract

Internet of Things (IoT for short) is an emerging Internet-based global information architecture that promotes the exchange of goods and services in the global supply chain network. IoT not only brings a lot of convenience to society but also faces a growing number of complex security risks. The basis of solving risk is accurate assessment of the possibility and the loss of the risk occurrence. However, in fact, when assess the risk, most companies still rely on personal work experience and knowledge to carry out emotional qualitative judgments, making the assessment results are not accurate. Through the combination of Analytic Hierarchy Process (AHP) and the practice of risk assessment, forming the risk assessment method using AHP, and the simulation experiment is carried out on the typical application of positioning system in IoT. The results show that the risk assessment method can be used to solve the risk assessment method which is combined with qualitative and quantitative analysis, which makes the result of risk assessment more scientific and accurate.
