Secure Many-To-Many Authentication and Key Agreement Scheme for Vehicular Networks

Abstract

Increase in demand for web and communication technology, vehicles will analyze and choose their all-time knowledge collected by varied cloud service suppliers (CSPs) in a conveyance network. However, in an exceedingly conveyance network atmosphere, period knowledge area units transmitted through wireless channels might result in security and privacy problems. To avoid access for third parties, vehicle authentication, and key agreement mechanism have been considered collectively the promising security measures in conveyance network environments. Besides, most of the solutions concentrate on authentication between one vehicle and one CSP. In such methods, the implementation of economical authentication for several vehicles and CSPs at the same time is typically difficult. Further, they're conjointly subjected to performance limitations because of the overhead incurred. to unravel these problems, we have a tendency to propose a many-to-many authentication and key agreement theme for secure authentication between multiple vehicles and CSPs. The projected theme will forestall unauthorized access and supply SK- security (strong key). To improve the service, the CSP solely has to broadcast associate degree anonymous messages sporadically rather than having to get a singular anonymous message for every vehicle. Similarly, once a vehicle needs to request the services of m CSPs, it solely has to send one request message rather than n. Therefore, the proposed theme not solely implements many-to-many communication however conjointly considerably reduces the computation and communication overhead.
