智能交通车联网的发展面临着无线网络通信安全与车载用户隐私保护等一系列具有挑战性的难题。针对该系列问题，文章提出了一种层次化的车联网移动云安全模型，车载移动终端使用其身份证书接入相应层次的云端进行身份认证，以确保获得安全稳定的车联网系统服务。同时，由于车载单元的快速移动性质，路侧设施难以支撑大密度的车载终端认证过程，结合云端充足的计算资源和强大的服务能力，可降低车载移动终端在身份合法性确认过程对于车联网路侧设施的处理性能要求，而使用匿名认证的方法可保护车辆的安全和位置隐私。

The development of IoV in ITS is facing a series of challengling problems, such as wireless network security and protection of vehicle privacy. Focusing on such series of problem, this paper presents a security model of hierarchical mobile cloud system where vehicles access to the corresponding levels of cloud system using identity certiifcates for safe and reliable service of IoV. Due to the rapid mobility of vehicle, RSUs are dififcult to support a large density of vehicle certiifcation process and thus combined with sufifcient computing resources and strong service capabilities of cloud, the requirement of processing performance of RSUs is reduced handing veriifcation of vehicle identiifcation legitimacy. Meanwhile, anonymous authentication can protect the safety and location pricacy of vehicle.
