Cryptanalysis of Authentication Schemes in Heterogeneous Vehicular Networks

Abstract

The rapid evolution of Heterogeneous Vehicular Network (HetVNETs) has introduced complex challenges in securing communication between vehicles and infrastructure. One of the most critical aspects of security in these networks is authentication, which ensures that only trusted entities can participate in vehicular communication. The use of various communication technologies in HetVNETs, including networks like 4G, 5G, and dedicated short-range communication systems, makes these systems vulnerable to different cryptographic issues. This paper provides a detailed analysis of current authentication methods in HetVNETs, highlighting their weaknesses against several types of attacks, such as replay, man-in-the-middle, and impersonation attacks. We evaluate the performance, scalability, and resilience of these methods under different attack scenarios. Based on our findings, we propose ways to enhance the security of authentication protocols in HetVNETs to ensure safe and reliable communication for future vehicular networks.
