面向车队的安全且具备隐私保护的移动性管理框架

Secure Mobility Management Framework with Privacy Preservation for Vehicle Platoon

针对异构车载网络中支持安全高效的移动性管理的问题,以及支持新兴的面向车队环境所面临的性能方面的挑战,文章基于Open Flow(OF)协议的软件定义网络(SDN)概念,提出了一种新的基于SDN的车联-蜂窝集成网络架构,同时引入一个统一的安全无缝IP通信框架。文章试图解决两个主要挑战:1)在考虑车辆的社会属性时,如何以隐私保护方式安全和灵活地建立群组;2)如何控制切换信令开销(主要由基于群组的切换认证和IPsec建立引入),并且当大量群组成员需要安全地访问因特网时,可以减少切换延迟。性能评估表明,文章所提出的方案在平均信令开销和切换延迟方面优于其他方案。

To address the problem of supporting secure and efficient mobility management in heterogeneous vehicular networking,as well as performance challenges in supporting emerging for vehicle platoon environments.In this paper,a new SDN-enabled VANET-Cellular integrated network architecture is proposed by following the SDN concept,which is based on the Open Flow（OF） protocol.And we introduce a unified secure and seamless IP communications framework.We try to address two major challenges：1） how to securely and flexibly set up the platoon in a privacy preserving way when considering the vehicles＇ social attributes,and 2） how to control the handover signalling overhead（mainly introduced by group based handover authentication and IPsec establishment）,and reduce handover latency when a large number of platoon members need to securely access the Internet.The performance evaluations demonstrate that the proposed proposal outperforms other schemes in terms of average signaling cost and handover latency.
