Abstract

The embodiment of the invention discloses a bidding file encryption and decryption method and device, equipment and a medium. The method is applied to a mobile terminal. A digital certificate is integrated in the mobile terminal, and the method comprises the following steps: sending a public key in the digital certificate to bidding equipment, so that the bidding equipment encrypts a target bidding file by using the public key to generate a target encrypted bidding file, and sends the target encrypted bidding file to bidding equipment; and obtaining the target encrypted bidding file from the bidding device, decrypting the target encrypted bidding file by using a private key in the digital certificate to obtain a target decrypted bidding file, and sending the target decrypted bidding file to the bidding equipment. According to the embodiment of the invention, the bidding file is encrypted and decrypted by utilizing the mobile terminal integrated with the digital certificate, and the bidding file encryption and decryption method is free of terminal limitation and convenient to operate.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of electronic bidding, and in particular to a method, device, equipment and medium for encrypting and decrypting bidding documents. Background technique [0002] With the development of the Internet age, online transactions of electronic bidding are becoming more and more frequent. [0003] At present, electronic trading platforms generally use USBKey as the storage medium of CA certificates. When encrypting and decrypting electronic bidding documents, it is necessary to insert a CA lock on a fixed PC terminal to realize encryption and decryption of bidding documents. [0004] This method requires bidding units to apply for different CA locks and install corresponding drivers when bidding on different trading platforms. The operation is cumbersome and can only be encrypted and decrypted on a fixed terminal. Contents of the invention [0005] In view of this, the present invention...
