通过SM2两方协同密码算法构造车联网"人车"逻辑实体的研究OA

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.
