Abstract
The invention provides an electronic bidding method for realizing CA interconnection and intercommunication, which comprises the following steps: step 1, providing an electronic bidding platform supporting various CA interface standards; step 2, the bid inviting client generates a bid inviting file data packet according to bid inviting information input by a bid inviting party, and uploads the bid inviting file data packet to the electronic bid inviting platform for release; step 3, the bidding client reads the type of the CA certificate used by the bidder, generates a bidding document according to the bidding information input by the bidder, encrypts the generated bidding document through the CA certificate used by the bidder, and uploads the encrypted bidding document and the type of the CA certificate to the electronic bidding platform; and 4, the electronic bidding platform selects the CA certificate used by the bidder to decrypt the bidding document. The invention enables the electronic bidding platform to adapt to different CA institutions, reduces the requirement of suppliers to deal with specified CA due to CA restriction, and reduces the additional cost of electronic bidding activities.
Description
Technical Field
The invention relates to the field of electronic bidding, in particular to an electronic bidding method for realizing CA interconnection.
Background
Since the electronic bidding method was published in 2013, the electronic development direction of the traditional paper bidding activity is gradually obvious. In order to solve the problems of trust and notarization in the bidding process, the digital authentication technology is widely applied to electronic bidding activities. The digital authentication technology is to adopt an asymmetric encryption technology, issue a CA medium by a certificate issuing authority, and realize non-repudiation and anti-cracking of information through the CA medium. CA authentication in the electronic bidding system is based on a digital signature authentication technology, and mainly realizes encryption and tamper resistance on bidding documents, bid evaluation reports and the like in the bidding link.
At present, because there are many CA issuing organizations (such as Beijing CA, Shanghai CA, CFCA, Shenzhen CA, etc.), and the CA organizations mutually divide the market and cannot mutually recognize each other, a supplier needs to handle keys of the CA organizations according to an electronic bidding platform when participating in bidding, thereby improving the trading cost, reducing the trading efficiency and further hindering the popularization of electronic bidding and bidding.
Disclosure of Invention
In view of the above-mentioned deficiencies of the prior art, the present invention provides an electronic bidding method for implementing CA interconnection and intercommunication, so that an electronic bidding platform can adapt to different CA agencies, reducing the CA restriction requirement for suppliers to handle specified CAs, and reducing the additional cost of electronic bidding activities.
In order to achieve the purpose, the invention adopts the following technical scheme: an electronic bidding method for realizing CA interconnection and intercommunication comprises the following steps:
step 1, providing an electronic bidding platform supporting various CA interface standards;
step 2, the bid inviting client generates a bid inviting file data packet according to bid inviting information input by a bid inviting party, and uploads the bid inviting file data packet to the electronic bid inviting platform for release;
step 3, the bidding client reads the type of the CA certificate used by the bidder, generates a bidding document according to the bidding information input by the bidder, encrypts the generated bidding document through the CA certificate used by the bidder, and uploads the encrypted bidding document and the type of the CA certificate to the electronic bidding platform;
and 4, the electronic bidding platform selects the CA certificate used by the bidder to decrypt the bidding document.
Further, the step 3 further comprises: and after the electronic bidding platform receives the type of the CA certificate used by the bidder, storing the type of the CA certificate in a database, and binding the type of the CA certificate with the user information of the bidder.
By adopting the technical scheme, the invention has the following beneficial effects: the interconnection and intercommunication of multiple CAs of the electronic bidding platforms are realized, so that a bidder transacts one CA, the electronic bidding platform can be suitable for multiple electronic bidding platforms, and the cost for transacting CA certificates is reduced.
Drawings
Fig. 1 is a flowchart of an electronic bidding method for implementing CA interconnection and interworking according to the present invention.
Detailed Description
The following description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will provide a better understanding of the nature of the invention.
As shown in fig. 1, the electronic bidding method for implementing CA interconnection of the present invention includes the following steps:
step 1, providing an electronic bidding platform supporting various CA interface standards, specifically integrating the certificate interface standards of different CA manufacturers on the electronic bidding platform, and packaging the interface standards provided by each CA manufacturer into relatively independent modules, so that even if the types of CA certificates are subsequently increased, the original system cannot be influenced, and smooth upgrading can be realized;
step 2, when bidding is performed, the bidding client generates a bidding document data packet according to the bidding information input by the bidding party, and uploads the bidding document data packet to the electronic bidding platform for release;
step 3, when the bid is placed, the bid client reads the type of the CA certificate used by the bidder, generates a bid file according to the bid information input by the bidder, encrypts the generated bid file through the CA certificate used by the bidder, and uploads the encrypted bid file and the type of the CA certificate to the electronic bid-placing platform;
and 4, when the bidding is started, the electronic bidding platform selects the CA certificate used by the bidder to decrypt the bidding document.
Preferably, after the electronic bidding platform receives the type of the CA certificate used by the bidder, the type of the CA certificate is stored in the database, and the type of the CA certificate (determined by its certificate serial number or organization name) is bound with the user information of the bidder.
After the technical scheme is adopted, if an electronic bidding platform A and an electronic bidding platform B are provided, wherein the electronic bidding platform A supports CFCA and Shanghai CA, the electronic bidding platform B supports CFCA and Beijing CA, and the existing bidder T1 has CA issued by CFCA, the bidder can participate in the bidding activities of the platform A and the platform B. If the electronic bidding platform C supports CFCA and is formally online, the system can be seamlessly accessed in a mode of configuring Shanghai CA certificates at present because business development needs to support Shanghai CA.
The above embodiments are merely preferred embodiments of the present invention, which are not intended to limit the scope of the present invention, and various changes may be made in the above embodiments of the present invention. All simple and equivalent changes and modifications made according to the claims and the content of the specification of the present application fall within the scope of the claims of the present patent application, and the present invention is not described in detail in the conventional technical content.
