Connected vehicles are generally equipped with many (dozens of, or even hundreds of) electronic and intelligent devices so that drivers can gain a more comfortable driving experience. Despite their numerous benefits, these technological developments have also created serious safety/security concerns. This article recapitulates the diversified attack surfaces of connected vehicles related to the technological developments from the perspective of the in-vehicle network. For each of the attacks, we discuss the rationale and the concrete methods presented in the literature. In particular, we illustrate how to launch successful attacks through the controlled area network (CAN) bus, electronic control units (ECUs), and in-vehicle infotainment system. The article also suggests some feasible solutions to the attacks demonstrated by the community. Considering the fact that vehicles are safety- critical, more practical and effective steps should be taken within the connected vehicle network toward securing connected vehicles and protecting drivers and passengers.

从车内网络角度看车联网安全


联网汽车一般都配备了许多（几十个，甚至上百个）电子和智能设备，以便驾驶员获得更舒适的驾驶体验。尽管有很多好处，这些技术的发展也带来了严重的安全问题。本文从车载网络的角度概括了与技术发展相关的车联网多样化攻击面。对于每种攻击，我们都会讨论文献中提出的基本原理和具体方法。我们特别说明了如何通过受控区域网络 (CAN) 总线、电子控制单元 (ECU) 和车载信息娱乐系统发起成功的攻击。文章还针对社区展示的攻击提出了一些可行的解决方案。考虑到车辆的安全性至关重要，因此应在联网车辆网络内采取更实际、更有效的措施，以确保联网车辆的安全并保护驾驶员和乘客。
