A system and method for realizing electronic bidding encryption in a vpn network

Abstract

The invention discloses a system for achieving electronic bidding encryption in a VPN network, and relates to the field of electronic bidding encryption systems. The system is characterized in that the system comprises a tendering / bidding system terminal, an external network, an access router and a firewall; the tendering / bidding system terminal comprises a tendering subsystem terminal, a bidding subsystem terminal, a bid opening subsystem terminal, a bid evaluation subsystem terminal and a monitoring subsystem terminal; the system also comprises CA certificate server groups corresponding to the subsystem terminals and an embedded VPN network; and multiple VPN clients which send data with routing information to a VPN general gateway by being accessed to the router are arranged in the external network. According to the invention, by use of the embedded VPN, data flow division is performed according to different user types of the tendering and bidding system; data encryption is achieved in the aspect of network communication; data transmissions speed is fast; efficiency is high; and encryption effects are favorable.

Description

technical field [0001] The invention relates to the field of electronic bidding encryption systems, in particular to a system and method for realizing electronic bidding encryption in a VPN network. Background technique [0002] Electronic bidding is a bidding activity completed in the form of data messages on the basis of traditional bidding. The electronic bidding system terminal provides technologies such as electronic bidding documents, digital certificate encryption and decryption, computer-aided bid opening / evaluation, etc., fully realizes the electronic and computer-aided bid evaluation of qualification bids, technical bids and business bids, and supports electronic sign-in, stream bid processing and The winning bid is locked, supporting electronic bid evaluation reports and bidding digital files, which greatly improves the efficiency of bidding and saves the cost of bidding. [0003] VPN is a virtual private network, and its function is to establish a private networ...
