A Study on Vehicle Monitoring Service Using Attribute-Based Security Scheme in Cyber–Physical Systems

Abstract

Cyber–physical systems (CPSs) is a manufacturing infrastructure that requires high reliability real-time automatic control characteristics. It is widely used in industrial fields such as production and transportation. An example is a future transportation network system that controls information such as sensors and actuators based on a network. However, CPSs are susceptible to cyberattacks as network-based interconnections increase. Data handled between a car and a fog server can put personal privacy at risk, so it is essential to introduce security technologies such as encryption. A login/password method is required to satisfy the demand for secure sharing and utilization by service users. Based on the attributes of these target service users, the authority to decrypt data is delegated to legitimate users, and a pull-in encryption method is required. In this paper, we propose a method to safely protect the system from attacks through the method of managing attribute-based delegation of authority. Using a semantic security model, the proposed system is proven safe against public attacks by malicious users, and it can be used to protect against attacks on a smart car.
