ESAC: An Efficient and Secure Access Control Scheme in Vehicular Named Data Networking

In Vehicular Ad Hoc Networks (VANETs), the mobility of vehicles and urban obstacles may make the traditional IP-based content delivery mechanisms; work sluggishly. To address this problem, we adopt the Vehicular Named Data Networking (V-NDN) architecture to enable efficient content delivery. However, secure access control and incentive design are rarely taken into account in existing solutions. In this paper, we propose an efficient and secure access control (ESAC) scheme for content delivery in V-NDN. Specifically, we construct the proxy re-encryption method to achieve access control and data confidentiality, while using pseudonyms and the identity-based signature to ensure anonymous authentication and content integrity. Furthermore, the revocation of illegal vehicles and updating operations are performed by the constructed proxy re-encryption method, which significantly reduces communication overhead. Finally, an incentive scheme is designed to improve the utility of NDN in VANETs. The security analysis shows that ESAC can meet the security requirements of the content delivery in VANETs while significantly lowering the overhead.
