Fine Grained Distributed Data Access Control with Portable Billing Scheme for Service Oriented Vehicular Network

Vehicular ad hoc network (VANET) is used to improve road safety. Service oriented vehicular networks support infrastructure based services like video streaming, content distribution, real time traffic concerns and internet access. Fine grained distributed data access network is used to meet the different requirements of users. This paper achieves security, privacy and billing in service oriented vehicular network. A portable electronic currency reduces the long authentication delay of the centralized AAA architecture. This paper also achieves the security properties of entity authentication, privacy, fraud electronic currency prevention, session key agreement, double-spending prevention, and non repudiated billing are achieved.
