The vehicular internet of things (VIoT) network is connecting smart commuters to elevate traffic problems and effectiveness that help to improve driving conditions for vehicles. Every ITS-based vehicle OBU and commuter might be interchangeable and used to give access permission for the various services during transportation such as infotainment, emergency service, environment service, road condition, etc. These services are suffering from the 1-affect-n problem, scalability, memory resources, computation, and communication overhead. In this paper, the authors proposed a novel decentralized group key management protocol for cloud-based vehicular IoT networks (GVIoTNet) to solve the problem of 1-affect-n and scalability by using the decentralized approach of group key access, key generation, key distribution, key update among vehicles and commuters. Further, by using the master key encryption approach, the average rekeying minimization is 84.84% with the GroupIT scheme. The minimization of rekeying reduces storage overhead and improves computation as well as communication overhead.
