An Effective Access Control Scheme for ICN Based Vehicle Exhaust Monitor System

This paper addresses the issue of accessing and controlling sensing data in the Vehicle Exhaust Monitor System (VEMS). The system relies on a variety of sensors, fixed on roads or vehicles, to measure data and ensure reliable transmission. However, due to the rapid movement of motor vehicles and users, there is a need for efficient and secure data request and distribution methods. To address this challenge, we propose a data request and distribution model based on Information Centric Networking (ICN), which can meet the requirements of high efficiency, large scale, and secure data distribution and acquisition. In our proposed model, the distributed sensors on both sides of the city road collect exhaust data and cache it in the local disk. Requests and transmission of exhaust data can be more efficient by fully utilizing the available resources through ICN. However, since the cache in the network can be retrieved by anyone, unauthorized access to exhaust data is a concern. To address this issue, we propose an access control mechanism based on XOR-coding to manage data access authority. Our proposed mechanism not only improves the utilization of in-network cache and reduces the consumption of network bandwidth, but also effectively protects user data security. We have demonstrated the feasibility of our solution through both theoretical proofs and simulation-based experiments.
