An efficient and secure mobile payment protocol for restricted connectivity scenarios in vehicular ad hoc network

摘要: Value-added applications in vehicular ad hoc network (VANET) come with the emergence of electronic trading. The restricted connectivity scenario VANET, where vehicle cannot communicate directly bank for authentication due to lack internet access, opens up new security challenges. Hence a secure payment protocol, which meets additional requirements associated is must. In this paper, we propose an efficient and protocol that aims at VANET. applies self-certified key agreement establish symmetric keys, can be integrated phase. Thus both computational cost communication reduced. Moreover, achieve fair exchange, user anonymity security.
