智能网联汽车安全综述

Intelligent and Connected Vehicle Safety Review

车联网与智能汽车的有机结合产生了智能网联汽车.智能网联汽车以人工智能、5G通信技术等新兴技术为基础,通过车载传感系统和信息终端来实现与人、车、路等方面的信息交换.然而,厂商将新兴智能网联技术集成到汽车中,为客户带来方便、快捷、智能和舒适体验的同时,也带来一些信息安全问题.介绍了智能网联汽车的发展趋势以及与日俱增的安全问题;在给出智能网联汽车定义与架构的同时,比较了“智能”与“网联”关系,以及与国内外技术路线的差异;对当前智能网联汽车所面临的安全威胁进行了汇总分析,结合智能网联汽车与传统汽车的技术架构差异将攻击划分为传统攻击与新型攻击两大类,并给出了每种攻击对应的安全防御对策;最后对当前智能网联汽车安全研究现状进行了分析和归纳,指出了当下环境的研究方向建议.

The organic combination of Internet of Vehicles and intelligent vehicles has produced Intelligent connected vehicle.Intelligent connected vehicle realizes the information exchange of people,vehicles and roads through on-board sensing system and information terminal,which is based on emerging technologies such as artificial intelligence and 5G communication technology.However,while the manufacturers integrate the emerging intelligent network technology into the car to bring convenience,rapidity,intelligence and comfort to customers,there are also many information security problems.This paper first introduces the booming trend of intelligent connected vehicles and the increasing security issues.While giving the definition and architecture of intelligent connected vehicles,the relationship between“intelligence”and“connected”and the differences in technical routes at home and abroad are compared.The current security threats faced by intelligent connected vehicles are summarized and analyzed.Combined with the technical architecture differences between intelligent connected vehicles and traditional vehicles,the attacks are divided into two categories:traditional attacks and new attacks,and the corresponding security defense countermeasures for each attack are given.Finally,the current securiy research of intelligent connected vehicles is analyzed and summarized,as well as the suggested research direction is pointed from the current environment.
