安全需求能否得到充分保障是车联网技术能否从实验室走向实际应用的关键.作为现代信息技术与传统工业深度融合的产物,车联网必须同时面对传统网络中存在的安全问题以及各类新技术应用中出现的新威胁.从车域网安全、车载自组网安全和车载移动互联网安全3个方面分析了车联网面临的安全威胁.在此基础上,分别从数字签名、身份认证、数据验证、可信计算4个方面对车联网安全提出了相应的解决方案.
Whether the security requirements can be fully protected is the key to whether the car networking technology can move from the laboratory to the practical application.As a result of the deep integration of modern information technology and traditional industries, car networking must face the security problems existing in the traditional networks as well as various types New threats in the application of new technologies.This paper analyzes the security threats faced by car networking from three aspects: security of car domain network, security of car self-organizing network and mobile Internet security of car.On this basis, Data validation, trusted computing four aspects of the car networking security put forward the corresponding solutions.
