Problems solved by technology

[0004] To sum up, the problems existing in the existing technology are: the server of the electronic credential system needs to process a large number of login and data transmission requests, and a large number of login requests have brought enormous pressure to the server; for the safe circulation of electronic credential, the distance between old and new devices is relatively large. close, and both are owned by the same user, there is no need to repeat the login-authentication process

Abstract

The invention belongs to the technical field of D2D communication. The invention discloses a D2D-based electronic credential security transfer method and system, and an electronic credential system. User equipment 1 (UE1) is connected with an electronic credential server (SERVER) through a communication network, and the user equipment 1 (UE1) is connected with user equipment 2 (UE2) through a D2Dchannel. The electronic credential server is provided with a certificate issuing module (CA), an authentication module (AS) and a data storage module (DB), and the user equipment is provided with a login module, a data transmission module and a D2D module. The same user owns more than one device, and one existing device (UE1) completes authentication and data transmission with an electronic credential server. Other equipment does not need to establish network connection with the electronic credential server again, and the transfer of the bill state is completed by establishing a D2D channel with the UE1. The electronic credential transfer system is reasonable in structure, communication resources of the electronic credential server can be saved, user operation is simplified, and credentialtransfer time is shortened.

Description

Technical field [0001] The invention belongs to the technical field of D2D communication, and in particular relates to a D2D-based electronic credential safe transfer method and system, and an electronic credential system. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: After a user successfully logs in using a device and downloads the relevant electronic credential information, if he purchases a new device and wants to synchronize credential data on the new device, he needs to use the new device Communicate with the server through the network, and download the electronic credential information from the server after repeating the login-authentication process. With the advancement of paper-removal and electronic billing systems, more and more users use electronic credential systems. The electronic credential system server needs to handle a large number of login and data transmission requests. A large number of request...
