Method for Executing Electronic Signature Based on Private Digital Certificate

摘要

According to the present invention, the digital signature method based on a private certificate is performed in an environment including an integrated client module, a user agency server, an integrated authentication server, an authentication server of a private certificate authority, and an authentication application program module of a private certificate authority. And receiving, by the integrated authentication server, a private certificate-based electronic signature request from the user institution server, wherein the electronic signature request is executed after the user institution server receives the electronic signature request from the integrated client module. Wow; A second step of transmitting, by the integrated authentication server, an electronic signature request to an authentication server of a private certificate authority; A third step of transmitting, by the integrated authentication server, the transaction identification information to the user institution server; An integrated authentication server is a step of requesting an electronic signature result from an authentication server of a private certificate authority, wherein the electronic signature result request is an electronic signature result request transmitted from a user institution server that has received the electronic signature completion fact from the integrated client module. A fourth step, which is executed after the integrated authentication server has received it; A fifth step of receiving, by the integrated authentication server, a result of the digital signature from the authentication server of the private certificate authority; The integrated authentication server includes a sixth step of transmitting the digital signature result to the user institution server.
