Method and system for remote bid opening and bid evaluation

Abstract

The invention relates to data safety technology, and particularly discloses a method and a system for remote bid opening and bid evaluation. The method includes the steps: uploading bidding documents, primarily encrypting the bidding documents and secondarily encrypting a primary encryption key; receiving and decrypting the bidding documents in an online manner, decrypting the primary encryption key by acquiring a secondary primary encryption key, and then decrypting the bidding documents by the aid of the primary encryption key; verifying validity of the bidding documents and generating a bid opening list when bid opening time comes; distributing bid inviting documents, the bidding documents and bid opening process documents; and performing evaluation according to preset evaluation standards to obtain bid evaluation results. The system comprises a bidding service subsystem, a bid opening service subsystem and a bid evaluation service subsystem, wherein the bid opening service subsystem is capable of decrypting the secondarily encrypted bidding documents in the online manner and providing the corresponding bid inviting documents, the bidding documents and the bid opening process documents to the bid evaluation service subsystem for evaluation. By the aid of the method and the system, safety of the bidding documents is facilitated, and decrypting efficiency is improved.

Description

technical field [0001] The present invention relates to data security technology, specifically an Internet-based remote bid opening and evaluation method and system, which is applied to the remote bid opening and bidding business of bidding, and can effectively improve the data security in the process of electronic bid opening and evaluation sex. Background technique [0002] At present, with the maturity of Internet technology, various network-based application services have been developed rapidly, and the remote bidding system (such as government procurement) is such an example. Remote bidding systems include remote bid opening process and remote bid evaluation process: [0003] The so-called remote bid opening refers to accepting bidding documents through the bidding service channel, decrypting the bidding documents on site or through the network, verifying their validity, reading the bidding documents, and generating a bid opening list; [0004] The so-called remote bi...

AI Technical Summary

Problems solved by technology

[0008] There are certain defects in the existing remote bid opening and evaluation schemes, which are mainly manifested in the lack of scientific consideration of the data security of the bidding documents, including the following aspects: Bidding documents all use simple symmetric algorithms or asymmetric algorithms Precession

Simply using symmetric algorithm encryption is not safe and easy to be cracked; purely using asymmetric algorithm keys, the speed of encryption and decryption is slow, and it is not easy to manage during use

Since the asymmetric algorithm needs to provide a private key for decryption, it often requires the user to provide the private key on site to complete the decryption, which brings security and efficiency problems
