Electronic signature implementation method based on state grid security technology architecture

Abstract

The invention discloses an electronic signature implementation method based on state grid security technology architecture, which comprises the following steps: acquiring user information containing auser identity, applying to an authentication institution for verifying the user identity according to the user information, and generating a user key pair for a user through a power intranet encryption machine; binding the user information with a private key in the user key pair, and carrying out segmentation processing on the private key; submitting user information to an authentication institution through a power extranet signature server, generating a user digital certificate based on the user information, and encrypting and storing the user digital certificate; a to-be-signed file uploaded by a user is obtained through a power extranet signature server, after the identity of the user is confirmed according to a user digital certificate, a segmented private key is called, and a complete user private key is obtained through a synthesis algorithm; and digital signature operation is completed according to the complete user private key. And the security and reliability of the electronic signature system are improved by encrypting and storing the user private key segment by segment, and the risk of stealing the private key is reduced.

Description

technical field [0001] The invention belongs to the technical field of electronic signatures, and in particular relates to an electronic signature realization method based on the security technical framework of the State Grid. Background technique [0002] With the increasing number and types of electronic document signing, the demand of enterprises for the compliance and validity of electronic contract signing, the demand for the efficiency of electronic contract management, and the demand for protecting the legal interests of enterprises are becoming more and more obvious. The way electronic documents are signed and managed creates new requirements. The traditional electronic signature technology relies on Ukey and other physical media. When signing a seal, Ukey needs to be called to identify the identity. At the same time, if the Ukey and pin code are lost, it is easy to cause corresponding losses due to official seal theft. In recent years, the emergence of cloud-based ...

The traditional electronic signature technology relies on Ukey and other physical media. When signing a seal, Ukey needs to be called to identify the identity. At the same time, if the Ukey and pin code are lost, it is easy to cause corresponding losses due to official seal theft.

In recent years, the emergence of cloud-based digital signature technology has separated from physical media to a certain extent and improved operational efficiency, but the security risks it brings cannot be underestimated.
