Secure authentication in motion: A novel online payment framework for drive-thru Internet

The security and privacy issues have been well investigated in typical vehicle ad hoc networks. However, considering the drive-thru Internet properties, in particular for a secure and in-motion payment services case, merely implementing the existing online payment schemes may be either infeasible or inefficient. In this paper, we propose an advanced online payment framework, which integrates three main features, including the novel pairing-free certificateless encryption, signature and semi-honest RSU-aided verification, and the CA-aided tracking and batch auditing, and providing following properties independently, e.g., achieving a higher trust level and supporting primary security services, introducing a semi-honest RSU to indicate more practicality, and optimizing the verifying and auditing efficiency for a large number of authentication requests case. Performance evaluations such as security analysis, efficiency analysis, and simulation evaluation show the security and feasibility of the proposed framework.
