Bayesian Game-Based Privacy Protection Method for Internet of Things Nodes under Fog Computing Architecture

Abstract

The invention discloses a Bayesian game-based privacy protection method for Internet of Things nodes under the fog computing framework, which is applied in an environment including Internet of Things nodes and fog computing nodes, wherein the Internet of Things nodes include a series of sensing nodes, realizing real-time online Monitoring, positioning traceability, remote control and other management or application functions; fog computing nodes, as edge nodes of the Internet of Things, have strong computing and storage resources, can support complex privacy protection calculations, detect IoT nodes, and implement privacy protection Various calculations of protection. The IoT node privacy protection method provided by the present invention is based on the Bayesian game model to model the malicious nodes and normal nodes existing in the actual IoT, and the fog computing nodes detect the IoT nodes according to the optimal probability, so that the The privacy leakage of networked nodes is minimal.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things security, and more specifically, relates to a privacy protection method for Internet of Things nodes based on a Bayesian game under a fog computing architecture. Background technique [0002] The Internet of Things combines physical objects and the Internet in different areas of life, such as industry, family, hospital, and environmental monitoring, and utilizes ubiquitous computing, embedded devices, communication technologies, sensor networks, Internet protocols, and applications to transform these objects from traditional become intelligent. However, due to the nature of IoT connectivity, an important issue facing IoT is security and privacy. [0003] Most IoT applications are connected by wireless communication. In practical applications, users more or less need to provide sensitive privacy information such as their identity information and geographical location, which are likely t...
