Embodiment

[0038] Electronic bidding system, as attached figure 1 As shown, it includes a server and a client. The client is used by the bidder or the tenderer. The communication between the client and the server is through the SSL protocol, so as to ensure the security and integrity of the transmitted data. For ease of distinction, the client used by the bidder is defined as the bidding client, and the client used by the tenderer is defined as the bidding client.

[0039] This embodiment takes invitation to bid as an example for illustration. When the tenderee has a demand for bidding, the tenderee prepares relevant prequalification documents, bidding documents and other bidding information, and the bidding client is used to obtain the bidding information and upload the bidding information to the server. . The bidding information is the pre-qualification documents and bidding documents uploaded by the bidding party. In this embodiment, the bidding information includes bidding documents...

Embodiment 2

[0061] The difference between this embodiment and Embodiment 1 is that this embodiment also uses blockchain technology to store and update the identity information and transaction information of the tenderer and the bidder, and establishes an electronic bidding system with authentic and reliable information, reducing the Trust cost, with data backup and traceability functions at the same time, so as to effectively prevent information from being tampered with.

[0062] The server also includes an identity verification module, a node registration module and a behavior recording module.

[0063] For the convenience of description, in this embodiment, the bid inviter, the bidder, and the bid evaluater are collectively referred to as users.

[0064] The identity verification module is used to obtain the registration information when the user registers on the electronic bidding system, and perform identity verification on the registration information. Specifically, the identity veri...

Abstract

The invention relates to the technical field of digital information security transmission, and particularly relates to an electronic bidding and tendering system and method. The system comprises a server, and the server is used for obtaining bid inviting information; the server is further used for generating public and private key pairs according to the bid inviting information, encrypting privatekey certificates in the public and private key pairs based on a Shamir threshold to obtain a plurality of private key ciphertext, and generating a bidding tool according to the public key certificates in the public and private key pairs; the server is also used for updating the bidding tools according to any private key ciphertext during bidding, and the updated bidding tools are in one-to-one correspondence with the private key ciphertexts; the bidding tool is used for obtaining bidding information, encrypting the bidding information to obtain a bidding ciphertext, and uploading the biddingciphertext and the private key ciphertext to the server; and the server is also used for generating a private key certificate according to the plurality of private key ciphertext based on the Shamir threshold during bid opening, and decrypting the bidding ciphertext according to the private key certificate. By adopting the scheme, the security of the private key certificate can be effectively ensured.

Description

technical field [0001] The invention relates to the technical field of digital information safe transmission, in particular to an electronic bidding system and method. Background technique [0002] With the maturity of Internet technology, various web-based application services have developed rapidly, such as electronic bidding. Electronic bidding is based on traditional bidding, electronic bidding documents, transmission and release with the help of computers and networks, so as to complete the bidding activities. In the process of electronic bidding, through information encryption, authority management, access control and other operations, electronic bidding documents are supervised, thereby reducing the occurrence of leakage of electronic bidding documents due to human factors. Therefore, in order to realize real electronic bidding management, the security of electronic bidding documents is particularly important. [0003] The existing electronic bidding is the same as ...
