Abstract
The invention discloses a system for encrypting outgoing data of databases on the basis of a DES (data encryption standard) algorithm. The system is characterized by comprising steps of 1), monitoring a computer central processing unit in real time by the aid of a database outgoing data identifying unit to judge whether the computer central processing unit transmits data instructions outwardly or not; 2), transmitting signals to notify a master control unit once the database outgoing data identifying unit discovers that the computer central processing unit transmits the data instructions outwardly; 3), automatically connecting the master control unit with the computer central processing unit, retrieving the data which are about to be transmitted by the computer central processing unit, and transmitting the data to a DES encrypting unit to encrypt the data; 4), enabling the master control unit to feed the encrypted data to the computer central processing unit and enabling the computer central processing unit to process the encrypted data in a next step. The system has the advantages of convenience in use, high processing speed, easiness in technical implementation, and the like.
Description
Technical field
The present invention relates to a kind of system database outgoi8ng data being encrypted based on des encryption algorithm.
Background technology
Along with the generally popularization of modernization of business, the advantages such as, saving resource convenient because office exists that office efficiency is high with no paper at all, file transmits and cost, thereby office is accepted by increasing enterprise with no paper at all.Exactly because its file transmits feature easily, also make the risk that enterprise's secret leaks greatly improve.
Especially enterprise is encrypted database outgoi8ng data, needs the clerical workforce of enterprise to be manually encrypted transmitting content, advocates today of efficiency first, requires to accomplish that the possibility that every a file is all encrypted is almost impossible.Therefore a kind of system that can be encrypted database outgoi8ng data is voluntarily badly in need of being developed.
DES(Data Encryption Standard), data encryption standards, speed, is applicable to encrypt the occasion of mass data, symmetric encipherment algorithm.For the development of said system provides technology possibility.
Summary of the invention
The present invention is directed to the proposition of above problem, and develop a kind of system database outgoi8ng data being encrypted based on des encryption algorithm.The technical solution used in the present invention is as follows:
System database outgoi8ng data being encrypted based on des encryption algorithm, is characterized in that comprising the steps:
1) by database outgoi8ng data recognition unit, whether computer center's processing unit being made to the instruction of outwards sending data monitors in real time;
2) make the instruction of outwards sending data once database outgoi8ng data recognition unit is found computer center's processing unit, send signal notice active cell;
3) described main control unit connects with computer center's processing unit automatically, and the data that computer center's processing unit is about to send are transferred, and then sends to des encryption unit to be encrypted;
4) last main control unit again by the data feedback of having encrypted to computer center's processing unit, be for further processing by computer center's processing unit.
In step 3), also comprise:
Whether need the selection step being encrypted by des encryption unit.
Owing to having adopted technique scheme, system provided by the invention has: easy to use, processing speed, technology realize the features such as easy.In addition, the realization of the method based on computer system, only need be compiled into the method corresponding program and can realize the upgrading to active computer, and therefore its cost is very cheap is suitable for extensive popularization.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of system of the present invention;
Fig. 2 is realization flow figure of the present invention.
Embodiment
The system that should be encrypted database outgoi8ng data based on des encryption algorithm as depicted in figs. 1 and 2, is characterized in that comprising the steps:
1) by database outgoi8ng data recognition unit, whether computer center's processing unit being made to the instruction of outwards sending data monitors in real time;
2) make the instruction of outwards sending data once database outgoi8ng data recognition unit is found computer center's processing unit, send signal notice active cell;
3) described main control unit connects with computer center's processing unit automatically, and the data that computer center's processing unit is about to send are transferred, and then sends to des encryption unit to be encrypted;
4) last main control unit again by the data feedback of having encrypted to computer center's processing unit, be for further processing by computer center's processing unit.
In step 3), also comprise: whether need the selection step that is encrypted by des encryption unit.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
Claims (2)
1. the system based on des encryption algorithm, database outgoi8ng data being encrypted, is characterized in that comprising the steps:
