Abstract

The invention relates to a system and a method for realizing electronic bidding and tendering encryption in a VPN, and relates to the field of electronic bidding and tendering, the system comprises atotal server, a bidder client, a bidder client, a bidder evaluator client and the VPN; the bidder client, the bidder client and the bidder evaluator client are connected to the VPN, and the VPN is connected to the total server; the system further comprises an encryption server and a decryption server, the encryption server is connected to the bidder client, the decryption server is connected to the bidder client, and the encryption server is used for generating an encryption key for the bidding file; the decryption server is used for decrypting the encrypted bidding file; and a transmission channel for transmitting a secret key is connected between the encryption server and the decryption server. The data transmission method and device have the effect of improving the safety of the data inthe transmission process.

Description

technical field [0001] This application relates to the field of electronic bidding, in particular to a VPN network-based electronic bidding system and method. Background technique [0002] Electronic bidding is a bidding activity completed in the form of data messages. In layman's terms, it is to abandon part or all of paper documents and complete bidding activities with the help of computers and networks. It is transmitted and released through the network, and the whole process of supervision is fully automated through encryption and workflow technology, minimizing the influence of human factors. [0003] Because the electronic bidding documents contain sensitive information such as prices and technical solutions. In order to ensure the security of the electronic bidding documents before the bid opening, the electronic bidding documents will be encrypted to ensure the security of the electronic bidding documents. In some related technologies, only suppliers provide encry...
