A Secure Data Forwarding Scheme in Vehicular Named Data Networking

摘要

In vehicular ad hoc networks (VANETs), vehicles' mobility and urban obstacles may cause frequent communication disconnections and sudden network changes. As a result, the traditional IP-based node-to-node content delivery mechanism does not adapt well to such changes in VANETs. To solve this problem, in this paper, we study the Named Data Networking (NDN) architecture to support efficient and secure data forwarding in urban VANETs. To meet security requirements, we adopt the encryption-based name obfuscation to achieve Interest-based access control. Moreover, the revocation of illegal vehicles and the updated operation are addressed by proxy re-encryption method, which saves the main communication overhead during the process. Finally, we design an incentive scheme to guarantee the utility of NDN in VANETs. The security analysis shows that the proposed secure scheme can satisfy security requirements of the data forwarding in VANETs. The performance analysis indicates that the overhead caused by the proposed secure scheme is low and acceptable.
