# Vcash: A Novel Reputation Framework for Identifying Denial of Traffic Service in Internet of Connected Vehicles

## TL;DR

Vcash introduces a reputation framework leveraging RSUs and market trading principles to efficiently identify and prevent denial of traffic service attacks in connected vehicle networks.

## Contribution

The paper proposes a novel reputation system using market trading rules and RSUs to improve trustworthiness and prevent false traffic event dissemination in connected vehicles.

## Key findings

- Effective in avoiding bogus event spread
- Vehicles must contribute to traffic detection to access services
- Simulation confirms improved trust management

## Abstract

Trust management of Internet of connected vehicles has been a hot topic during the recent years with the rapid development of UGV technologies. However, existing resolutions based on trustworthiness verification among vehicles make the traffic event transmission quite inefficient. In this paper, we assume that the deployed RSUs can provide efficient communication between any pair of RSU and vehicle, and propose Vcash, a reputation framework for identifying denial of traffic service, to resolve the trustworthiness problem in the application level of the Internet of connected vehicles. In our reputation framework, every vehicle communicates with the RSU directly for traffic event verification, and spread verified traffic event notification. We borrow the idea of market trading, and set up trading rules to restrict the malicious vehicle's spread of false message, and to encourage vehicles to contribute to the traffic event monitoring and verification. To evaluate the effectiveness of our reputation framework, we conduct simulation experiment. Our experiment results indicate that our proposal manages to avoid bogus event spread, and a vehicle in our framework has to contribute to the traffic event detection to normally employ the traffic service.
