Problems solved by technology

[0002] Many of the traditional encryption and decryption technologies are based on the principle of cryptography to convert specific files according to fixed mathematical functions to achieve encryption. The fixed mathematical functions have relatively strong regularity, and the industry's notification is also relatively strong. It is easy to crack through general rules. , the electronic bidding document of electronic bidding is a confidential document, which requires high encryption

Embodiment Construction

[0009] exist figure 1 In the shown embodiment, the system of the present invention includes: a database, which is used for storing user names and passwords, and is also used for temporarily storing encrypted relations and supporting users to download encrypted relations. User identity; the transmission function unit is used to write the downloadable encryption relationship into the database, and is also used to accept and forward user operation requests; the encryption function unit is used to call the encryption relationship generation component to encrypt the file The protection is used to call the encryption relationship output component to export the encryption relationship to the transmission function unit; the decryption function unit is used to call the encryption relationship generation component to decrypt the encrypted protected file to release the protection of the file; the encryption relationship generation component, It is used to generate a random encryption rel...

Abstract

The invention discloses an electronic tender document multi-layer encryption and decryption method used for electronic tendering and bidding. The method comprises the following steps: a user logs in to a system through a login function unit; The encryption function unit invokes the encryption relation generating component to encrypt and protect the file, and generates the encryption relation, which is imported into the mobile U disk; the encryption relation is imported from a mobile U disk to the encryption relation generating component, and the encryption relation generating component decrypts the file. This technology adopts a random cryptographic relationship to encrypt the file with one more layer in essence, and realizes the effect of multi-layer encryption in the simple encryption process.

Description

technical field [0001] The invention relates to the field of encryption, in particular to a multi-layer encryption and decryption method for electronic bidding documents used in electronic bidding. Background technique [0002] Many of the traditional encryption and decryption technologies are based on the principle of cryptography to convert specific files according to fixed mathematical functions to achieve encryption. The fixed mathematical functions have relatively strong regularity, and the industry's notification is also relatively strong. It is easy to crack through general rules. , the electronic bidding document of electronic bidding is a confidential document, which requires high encryption. Contents of the invention [0003] The technical solution adopted by the present invention to solve its technical problems is: [0004] The electronic bidding document multi-layer encryption and decryption method for electronic bidding of the present invention comprises the ...
