On the Security of a Secure and Computationally Efficient Authentication and Key Agreement Scheme for Internet of Vehicles

초록

In the Internet of Vehicles (IoV) environments, vehicles and roadside units (RSUs) communicate predominantly through public channels. These vehicles and RSUs exchange various data, such as traffic density, location, speed, etc. Therefore, secure and efficient authentication and key establishment (AKE) are needed to guarantee user privacy when exchanging data between vehicles and RSUs. Recently, a secure and computationally AKE scheme have been proposed to construct secure IoV environments. In their research, the authors asserted that their AKE scheme provides comprehensive security properties, protecting against various potential threats while simultaneously ensuring session key integrity, robust mutual authentication. This paper proved that the previous scheme does not prevent various attacks using logical and mathematical analyses. Moreover, we demonstrated that this scheme does not meet the essential security requirements and correctness of security assumptions. We perform the simulation proof using AVISPA, which is well known as a formal verification tool. To enhance the resilience of attacks, we propose solutions aimed at developing more robust and efficient AKE for IoV environments.
