MANAGEMENT SYSTEM AND METHOD FOR SECURE SIGNING OF CERTIFICATES

摘要

A management system and a method for secure signing of certificates, which have a certificate signing subsystem set up in a device of a controlled management site, unless authorized externally, internal data of the subsystem cannot be accessed arbitrarily, and each unit applying for a certificate needs confirmation of identity to increase the security of certificate application and signing. In addition, the certificate signing subsystem is a device with arithmetic capability, which operates fast and can increase the efficiency of certificate signing. Because units or companies applying for certificates do not need to set up a certificate signing system by themselves, provided that they are connected to the certificate signing subsystem of the present invention, certificates can be applied for and obtained, thereby saving business operating costs.
