摘　　要：为了解决现有手机数字钥匙产品单向信息传输、密钥生成造成安全隐患,以及授权机制不健全等问题,设计了一款通过手机数字钥匙远程控制车辆的系统。从车主的数字钥匙授权和车辆操作,用户更换或丢失手机的特殊应用的系统设计,到车主主动发起及被授权者主动发起的2种远程授权的执行方式,均进行了详细的阐述。整套系统采用双向反馈环节、信息加密和暗文传输,以及密钥定期滚动的安全措施。结果表明,该系统的设计更加安全可靠。In order to solve the problems of security risks caused by one-way product information transmission, and keygeneration, as well as imperfect authorization mechanism and other issues, this paper presents a design of a remote vehicle control system through mobile phone digital key, from the design of owner＇s digital key authorization and vehicle operation, system design of special application for changing and losing mobile phone, to the two remote authorization execution modes initiated by the owner and/or the authorized person, and all the above contents have been elaborated in detail. The whole system adopts a security system with two-way- feedback link, information encrypfion and cryptography transmission, and periodically scrolling key. The results show that the system is safer and more reliable in design.
