PHYSICAL LAYER SECURITY IN RIS-ASSISTED V2V COMMUNICATION

Abstract

Physical layer security (PLS) aims to ensure the confidentiality and authenticity of transmit- ted data by capitalizing on the inherent randomness of wireless channels. Owing to the popularity of intelligent transportation systems (ITS), PLS research has sparked renewed interest in the wireless research community. This paper investigates the performance of secure communication in a vehicle-to-vehicle (V2V) communication scenario using a reconfigurable intelligent surface (RIS). Additionally, we introduce the concept of non-orthogonal multiple access (NOMA) to enhance communication efficiency in V2V networks. This study aims to comprehensively analyze secrecy performance, including parameters such as secrecy outage probability (SOP) and probability of non-zero secrecy capacity (PNZSC). Our research aims to demonstrate the effectiveness of RIS in providing secure and reliable communication within V2V NOMA networks. Ultimately, our study contributes to advancing secure communication protocols in ITS.
