Third-party platform electronic contracting system based on electronic signature technology

Abstract

A third-party platform electronic contracting system based on the electronic signature technology comprises contracting party client sides and a third-party contracting platform. Contracting parties hold the same or different digital certificates, and the third-party contracting platform is used for electronic contracting, can provide integrated verification and timestamps for different certificate chains, certificate states and certificate validity periods and guarantees accuracy and validity of mutual electronic contracting of the contracting parties held the same or different digital certificates issued by the CA (certification authority). The third-party platform electronic contracting system uses the electronic signature technology for decomposition, simulation, reconstruction, recombination and solidification of critical steps, critical factors and critical processes, so that technological holes of existing electronic contracting are made up, and accuracy and validity of electronic contracting are guaranteed.

Description

technical field [0001] The invention relates to an electronic signature technology, which is used for electronic contracting by both parties in an electronic contract with a digital certificate, and is a third-party platform electronic contract system based on the electronic signature technology. Background technique [0002] In China, both parties to the electronic contract use digital certificates to carry out a convenient, safe and effective electronic contracting model that has been explored for many years. The current electronic contracting method generally adopted by both electronic contracting parties simply uses their respective digital certificates to electronically sign the contracting data. The steps of this kind of electronic contract generally do not exceed three steps, namely Party A's signature, Party B's signature and their respective retention. The signature verification process is simple, random or even cancelled, which cannot strictly guarantee the safety,...

Problems solved by technology

[0006] The problem to be solved by the present invention is: there are three problems in the existing electronic contract. One is that one contracting party cannot immediately know the certificate status and validity period of the electronic signature certificate of the other party, especially the certificate status and validity period of different types of electronic signature certificates cannot be known. The validity period; the second is that it cannot effectively support the mutual verification of electronic signature certificates issued by different CA institutions; the third is the lack of electronic contracting steps, such as the lack of non-repudiation of the contracting time between the two parties, the lack of certificate validity verification, and the lack of integrity of retained data. loophole
