Abstract

The invention relates to the technical field of electronic signatures, in particular to an electronic signature system which is suitable for a public key cryptographic technology and supports a commercial cryptographic algorithm. Comprising an infrastructure unit, a user service unit, a signature management unit and a safety protection unit, the infrastructure unit is used for constructing a system network architecture; the user service unit is used for identifying a user and providing a signature service; the signature management unit is used for managing and controlling a signature function; the safety protection unit is used for improving system safety. The design of the invention can be suitable for multiple languages and various document formats, and supports public key cryptography and commercial cryptography algorithms; according to the method, autonomous controllability of information security can be realized, the document is prevented from being counterfeited, tampered and repudiated, and the method is safe and reliable, so that the signature document has enough legal efficacy and high authority; the method can meet the requirements of the user for obtaining and using the electronic signature, guarantees the compliance and data security of the user for signing the file, helps the enterprise informatization transformation, and improves the operation and management efficiency.

Description

technical field [0001] The invention relates to the technical field of electronic signatures, in particular to an electronic signature system suitable for public key cryptography and supporting commercial cryptographic algorithms. Background technique [0002] With the development of the electronic authentication service industry, the electronic signature application product market has developed rapidly, and a product system of identity authentication, authorization management, electronic signature, information encryption and decryption, trusted data message, and secure transmission has been formed, with more than 50 related products. It includes a series of innovative products in emerging fields such as mobile Internet, cloud computing, Internet of Things, and blockchain, which provide strong technical support for the development of the electronic certification service industry. At present, domestic electronic signature products using PKI technology are not uncommon, and th...

Problems solved by technology

[0003] Many electronic signature products are not closely integrated with PKI technology, do not even use PKI technology, and do not strictly follow the public key cryptography standard system. In terms of electronic seal generation and verification, electronic signature data generation and verification, the process is not standardized, verification Not strict, there are potential security risks; most ordinary electronic signature systems only support the RSA algorithm and not the domestic commercial encryption algorithm, such as the SM2 algorithm, which is not conducive to the development of information security in China; it cannot be realized without adaptation with domestic software and hardware Self-controllability of my country's information security

[0004] However, there is currently no electronic signature system that is applicable to my country's public key cryptography and supports commercial cryptographic algorithms
