Announcement protocol in Internet of Vehicles (IoV) is an intelligent application to enhance public safety, alleviate traffic jams and improve transportation quality.It requires communication between vehicles, roadside units and pedestrian to disseminate safety-related messages.However, as vehicles connected to internet, it makes them accessible globally to a potential adversary.Safety-related application requires a message to be reliable, however it may intrude the privacy of a vehicle.Contrarily, if some misbehaviour emerges, the malicious vehicles must be able to traceable and revoke from the network.This is a contradiction between privacy and accountability since the privacy of a user should be preserved.For a secure communication among intelligent entities, we propose a novel announcement protocol in IoV using group signature.To the best of our knowledge, our work is the first comprehensive construction of an announcement protocol in IoV that deploys group signature.We show that our protocol efficiently solves these conflicting security requirements of message reliability, privacy and accountability using 5G communication channel.The performance analysis and simulation results signify our work achieves performance efficiency in IoV communication.
