Description
Technical field
Patent of the present invention is related to encryption technology field, is specifically related to a kind of without fixed algorithm key encryption technology.
Background technology
In the hyundai electronics epoch, the storage and exchange of data, it usually needs encryption, to prevent in unauthorized feelings
Other people do not access under condition.Encryption is to change original information data with certain special algorithm so that even if the user of unauthorized
Encrypted information, but the method because not knowing decryption are obtained, still can not understand the content of information.
Existing encryption technology will rely on fixed Encryption Algorithm, such as AES and MD5 etc..Encryption Algorithm namely into
A kind of encrypted method of row, is widely used in various encryption technologies！The basic process of existing data encryption is：To being bright originally
The file or data of text are handled by certain algorithm, become one section of unreadable code, commonly referred to as " ciphertext ", make it
Original content can only can be just shown after corresponding key is inputted, approach in this way protects data not by not to reach
The purpose that licensed people steals, reads.The inverse process of the process for decryption, will the coding information be converted into its original data
Process.
Existing encryption technology is stored with these algorithms all there are basic secret key and algorithm inside encryption software,
Once algorithm is revealed or software is cracked, data will have the risk accessed by people without approval；In addition, existing encryption
Most of technology can be by Brute Force, although very long the time required to current Brute Force, the cost is higher,
The appearance of quantum computer will break this general layout so that Brute Force becomes more and more easily, therefore existing data add
Secret skill art security cannot get certain guarantee.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides one kind and is not easy to be cracked, and security performance is high without fixed algorithm
Key encryption technology.
The technical solution adopted by the present invention to solve the technical problems is：
It is a kind of without fixed algorithm key encryption technical method, which is characterized in that it is described without fixed algorithm key encryption skill
Art includes step used below：
（1）Random disorder code is generated using USBKEY, and random disorder code is saved as into random mess code file；
（2）Using USBKEY generation stochastic arithmetic symbol tables, and stochastic arithmetic symbol table is saved as into stochastic arithmetic symbol list file；
（3）Using USBKEY generations file accidental enciphering position, and it is random that file accidental enciphering position is saved as file
Encrypted location file；
（4）User inputs password, and password is accorded with table and timestamp computing by stochastic arithmetic（Computing mode is low level pair
Together, high-order insufficient digit carries out computing again according to the mode that low level aligns, and if a high position exceeds, removes automatically beyond digit）.Into
The female secret key of generation；
（5）Initial data is accorded with into table using stochastic arithmetic and random disorder code file carries out computing（Take not-carry but guarantor
Stay the computing mode of carry digit）, generate mixed file；
（6）Mixed file passes through female secret key computing using stochastic arithmetic symbol table（Take not-carry but partial carry number
Computing mode）, generate ciphertext（7）By accidental enciphering document location, ciphertext position is selected；
（8）It encrypts file and user password and computing is carried out to ciphertext（Take not-carry but partial carry number, low level pair
Together）,（Choose position that initial data is taken to participate in computing, unselected position data is constant, is not involved in computing, and operator table is same,
Position is chosen to participate in computing, unselected position is not involved in computing）, final encryption file is generated, and is supplied to user；
（9）Out of order code file, stochastic arithmetic symbol table, female secret key, accidental enciphering position paper are supplied to user or deposit
In USBKEY, initial data encryption is completed.
The beneficial effects of the invention are as follows：In the encryption technology of the present invention, any Encryption Algorithm is not stored in the data file
Or secret key, also without fixed algorithm and basic secret key, therefore even if encryption software is cracked or dis-assembling will not be right
Data safety generates threat, does not also possess the necessary condition of Brute Force, and the data file encryption that the present invention generates is not easy to be broken
Solution, safety coefficient are high.
