Group Based Dual Mode Key Management Scheme for Secure Communication in Vehicular Ad Hoc Networks - 2021

Research Area:  Vehicular Ad Hoc Networks


Vehicular ad hoc networks (VANETs) provide similar services at various service points, so selecting the efficient service among the available services is a crucial task. Similarly, accessing services to exchange time-critical messages demands secure schemes. In this work, an efficient group-based dual mode key management (G-DMKM) scheme is proposed to select efficient service and the secure route to access the service. In G-DMKM for each session, the base stations are grouped according to localization in a time window manner which restricts the key and group lifetime. The time-domain randomization technique is used to generate a group key for each group and is shared between all stations and vehicles. Vehicles are authenticated for communication based on group and private keys. The private key is generated by the base station under which the vehicle is located. In G-DMKM, the multi-attribute location selection approach (MALSA) computes the multi-attribute service fitness (MASF) for each service to select the optimal service from the available services. Furthermore, Secure Transmission Support (STS) estimates the STS value for each route identified towards the service point, and the route with the highest STS support is selected for secure access to the service and data transmission. Simulation results show that the inclusion of an STS-supported route improves G-DMKM efficiency in all aspects compared to the conditional privacy-preserving authentication (CPAS), Proxy Based Authentication Scheme (PBAS), and Secure Privacy-Preserving Authentication Scheme with Cuckoo Filter (SPACF).
