PROJECT TITLE :

TPPR: A Trust-Based and Privacy-Preserving Platoon Recommendation Scheme in VANET

ABSTRACT:

A novel vehicle driving paradigm known as the vehicle platoon, which organizes a group of vehicles in the nose-to-tail structure, has been given consideration as a potential solution to alleviate traffic congestion and improve the comfort of travel. In a system like this, the performances of the head vehicles are typically evaluated based on the feedback received from the user vehicles. An interesting problem has arisen, which is how to choose a suitable and dependable head vehicle without compromising the users' ability to maintain their vehicles' privacy. In this piece, we present a trust-based platoon recommendation scheme that we call TPPR. Its purpose is to enable potential user vehicles to avoid selecting the malicious head vehicles by recommending platoons that protect users' privacy. Each user vehicle in TPPR is assigned a trust value, and the reputation score of the head vehicle is determined by applying a truth discovery process to the data. This is the fundamental idea behind TPPR. Pseudonyms and the Paillier cryptosystem are utilized in order to protect the confidentiality of the vehicles. In addition, novel authentication protocols are designed to ensure that only valid vehicles (that is, vehicles that hold truthful trust values and are able to join the vehicle platoon) are able to pass the authentication. This is done to ensure that only valid vehicles can join the vehicle platoon. To demonstrate that the proposed TPPR scheme is safe against a variety of complex assaults in vehicular ad hoc networks, an exhaustive security analysis is carried out. In addition, comprehensive simulations are carried out in order to demonstrate the correctness and efficiency of the proposed scheme.
