Identity construction and signature method for replacing U shield

Abstract

The invention provides an identity construction and signature method for replacing a U shield, and the method comprises the steps: generating an account activation code according to a user identity construction request and storing the user identity information; distributing private keys according to the user identity information and the account activation code sent by the user electronic device, storing the identity information of the user electronic device, and binding the user identity information, the identity information of a user electronic device and the private keys; comparing the useridentity information and the identity information of the user electronic device with the user identity information and the identity information of the user electronic device which are stored already,authorizing the user electronic device to perform the signature operation if the information is consistent; receiving signature data sent by the user electronic device and is generated by signing withthe private key thereof, and verifying the signature data by using a public key. The method binds the user identity information, the identity information of the user electronic device and the privatekey, and the private key is stored in the electronic device. The U shield function is implemented by the electronic device, and the U shield is not required to be distributed, thereby saving the costand simplifying the business process.

Description

technical field [0001] The present invention involves providing a technical mechanism combining online and offline distribution, authentication, signature and write-off to ensure the security and convenience of using authentication and signature services, which can replace similar services on the Internet. A method for signing a U-shield and other authentication hardware, in particular to an identity construction and signature method for replacing a U-shield. Background technique [0002] The traditional U-shield is time-consuming and labor-intensive for the issuing supervisor. The issuance, replacement, and cancellation cycle of the entire business is too long, which may cause the parties to miss the bidding opportunity. The USB-Shields issued by the competent authorities in various places cannot communicate with each other, so that the parties hold a large number of USB-Shields according to different businesses, which brings inconvenience and the risk of possible loss to t...
