摘　　要：由于多人共用同一辆汽车的情况广泛存在,以车牌号为唯一标识生成的逻辑实体难以支持自动缴费等需要同时标识汽车和汽车当前使用人的车联网应用。为了解决这个问题,对SM2两方协同密码算法进行了研究,该算法生成一种安全可信的“人车”逻辑实体,标识该逻辑实体的私钥必须在用户私有智能设备(如:智能手机、智能手环等)和用户汽车共同参与计算时才能使用,为业务提供身份认证、加密传输、加密存储等全面支持。As a vehicle is usually used by several users,using license plate number as the unique identity of logical entity is hard to support Internet of Vehicles applications such as autopay,which need both the vehicle's identity and the vehicle user's identity.In order to solve the problem,two-party algorithm SM2 is researched.The algorithm generates a“person-vehicle”logical entity using private key as the unique identity.The private key can only be used when both the user's private devices(such as smart phone and smart wristband)and the vehicle join the computing,so as to provide comprehensive support such as identify authentication,transport encryption and storage encryption for the business.
