Secure data communication for wireless mobile nodes in intelligent transportation systems

Intelligent Transportation Systems (ITS) is one of the demanding area of research based on fast communication services. However, these networks are suffered with some congestion, routing and security issues especially in urban areas and cause of delay and computational complexities issues and lead to late messages delivery or data congestion. The Unmanned Ariel Vehicles (UAV) or drones and Internet of Vehicles (IoV) are facilitating ITS networks by collecting the data from road nodes and forward to the Road Side Units (RSU) or to the backbone architecture for decision making. This strategy will open new threats and challenges in the form of security, user privacy and other malicious activities. The traditional security and authentication mechanisms have not been feasible due to their complex and heavy computational processing. This study presents a novel Secure Data Communication in Drone Enables Internet of Vehicle (SDCD-IoV), solution for authentication among vehicle nodes, RSU and trust authority database in ITS networks. The proposed system is based on three main phases including initialization, registration, and authentication. The proposed solution provides the authentication mechanism to fulfill the security requirements to intelligent mobile nodes and provides node anonymity where vehicle nodes and drones are protected the identity during data transmission. The second important contribution of proposed solution is unlinkability where the network prevents them from adversary. Traceability and mutual authentication are also considered where nodes check malicious action and real identity of nodes recovery and verifying the messages from other entities. The proposed solution is tested in terms of time cost, computational cost, overhead in the presence of different number of nodes and velocities. The proposed solution achieved the high performance as compared to existing solutions.
