Embodiment 1

[0022] This application is applied to the electronic bidding platform, which realizes the encryption of bidding information when bidding, and realizes the decryption of bidding information when opening bids.

[0023] Encryption and decryption encryption system for remote bid opening type bidding, as attached figure 1 As shown, including encryption subsystem, decryption subsystem, database and client. In this embodiment, the client is a smart device used by the bidder. Extraction rules are pre-stored in the database. The extraction rules are to extract numbers or letters from the information to be extracted. The information to be extracted includes bidding information and encryption keys. In this embodiment, the extraction rules are to extract numbers from the information to be extracted. In other In an embodiment, the extraction rule is to extract letters from the information to be extracted.

[0024] The client terminal is used to obtain bidding information, which is a docu...

Embodiment 2

[0035] Since the encryption key is not saved in the system, when the bidder loses or forgets the encryption key, the bidder cannot decrypt the bidding information, resulting in the failure of the bidding.

[0036] The differences between this embodiment and Embodiment 1 are:

[0037] as attached figure 2 As shown, the encryption subsystem also includes an information extraction module and a secret key backup module. The information extraction module is used to extract verification information from bidding information and send the verification information to the encryption module. The bidding information is the bidding document, and the bidding document includes the bidding document, and the first few pages of the bidding document are the cover and the table of contents. In this embodiment, the information extraction module extracts the first N pages of the bidding document as the verification information, and the value of N can be determined according to the bidding documents...

Abstract

The invention relates to the technical field of digital information security transmission, especially to an encryption and decryption encryption system for remote bid opening type bidding and tendering. The system comprises an encryption subsystem and a decryption subsystem, the encryption subsystem is used for generating an encryption secret key according to bidding information uploaded by a userside, encrypting the bidding information according to the encryption secret key to generate a primary ciphertext, generating a public and private key pair according to the encryption key, and encrypting the primary ciphertext according to the public key to generate a secondary ciphertext; and the decryption subsystem is used for decrypting the secondary ciphertext according to the private key toobtain the primary ciphertext, and decrypting the primary ciphertext according to an encryption key uploaded by the user side to obtain bidding information. By adopting the scheme, the technical problem of low security of bidding information during remote bidding in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of safe transmission of digital information, in particular to an encryption and decryption encryption system for remote bid opening type bidding. Background technique [0002] With the development of Internet technology, various transactions have changed from offline transactions to online transactions, such as electronic bidding and bidding platforms, where the bidding party prepares pre-qualification documents, bidding documents, etc. and uploads them to the electronic bidding and bidding platform, and the electronic bidding and bidding platform announces the bidding Announcement, bid invitation and other operations, the bidder prepares pre-qualification application documents, bidding documents, etc. and uploads them to the electronic bidding platform. When the bid is opened, the key information in all bidding documents is disclosed to all bidders, and the bidding is connected through the electronic bidding...
