Description

Eight kinds of digital informations without logic hardware encryption Combination of Methods

Technical field

The invention belongs to the cryptography category in the private communication technology field, relate to eight kinds to digital information carry out without logic hardware encryption method.

Background technology

At government's net, military information, diplomacy, important commercial field, the safe transmission of information is the problem that becomes more and more important, aspect the cryptography that supports modern communication, instantly employed key one is limited length, the 2nd, recycle, this all provides chance for the decoding work of usurping after the enciphered message, and a Duan Zhongke recovers key from the intercepting code, and this is a deficiency of present secure communication.

Summary of the invention

The technical problem to be solved in the present invention is the hardware encryption method without logic that discloses eight kinds of digital informations.

The technical scheme that the present invention deals with problems is the cryptography method that adopts in life cycle indefinite length, do not recycle, and reaches the effect that can't recover key.

Eight kinds of encryptions of the present invention adopt irregular physical method to generate with key, it is for subsequent use that the rear communicating pair of generation is respectively held the spacious good cipher key store of depositing of a identical content, and use pointedly one of them by the Encrypt and Decrypt approach of appointing, also gradable time multiple use.

Concrete grammar is finished by following steps

1. transmitting terminal is encrypted processing with the true form battle array by the encrypting module of appointing;

2. enciphered message is sent to receiving terminal;

3. after receiving terminal received enciphered message, the encrypting module by correspondence carried out corresponding oppositely decryption processing, thereby recovers the true form battle array;

4. to be divided into according to the method difference be eight kinds to use therein functional module, deposit in advance spacious good after each portion for subsequent use of both sides, content is identical.

Specifically the implementation method of eight kinds of modules is described below:

One, the addition at one's own department or unit

Be used for doing the function code that has generated of key and true form only in corresponding position one's own department or unit addition, do not consider carry, 1+1=0 during binary system; The 8+7=5 during decimal system; A+8=2 during hexadecimal.Binary Zero-1=1 during reduction; The 5-7=8 during decimal system; 2-8=A during hexadecimal does not consider borrow.And these three true forms of " 1 " " 8 " " A " have obtained the reduction at one's own department or unit with " 0 ", " 5 ", " 2 " code of working after receiving.

Two, one's own department or unit true form subtracts function code

Take hexadecimal as example, be A9 such as true form only, function code is 1B, and A9-1B=9E. does not consider borrow; 9E+1B=A9. does not consider carry during reduction, reduces successfully two, method is identical during the decimal system.

Three, one's own department or unit function code subtracts true form

Only take hexadecimal as example: be A9 such as true form, function code is 1B.1B-A9=72, does not consider borrow; 1B-72=A9 does not consider borrow during reduction.

Relatively two, three as can be known, and when true form was identical with function code, the subtraction at one's own department or unit was that effect is different because the exchange of subtrahend and minuend obtains respectively working code 9E and 72.

Above three kinds of situations are because advancing between data, borrow relation before and after need not considering, can be from not segmentation deal with data chains to tail, and be the digital watermark that does not increase working code length, be particularly suitable for voice encryption, especially be suitable for field telephone.

When processed voice was encrypted, unified binary true form and the corresponding processing key of using carried out work, can only come Sequential output according to the talker to the encryption of voice by postponing a bit, and instantaneity and successional effect are all fine.

Four, the addition of carry backward

Change low method behind traditional front height, allow the addition carry backward of digital string, take hexadecimal as example: AB is true form .CD when being function code:

During reduction

What need pay special attention to is, the addition of carry is particularly useful for voice encryption backward, and is especially good to the cipher round results of field telephone, diplomatic code phone, sends successively such as AB123 because voice sequence is from left to right the sounding according to the teller Be AB front, need during with traditional addition process process after the segment, affect instantaneity and the connectivity of voice, can well address this problem during to the method processed voice encryption of laggard borrow.

Five, the true form of borrow subtracts function code:

Take hexadecimal as example, true form is A9C, and function code is 7BF6, first 6 back that are spliced to true form, becomes A9C6.

3EC5+7BF=A9C6. during reduction

After among the A9C6 6 removed, restore true form A9C.

Here allowing true form Duo one method than function code is to guarantee enough subtracting, if fill non-zero numeral in the next function code, run into 0 o'clock both sides and all automatically get following non-zero number and come usefulness, common plus-minus for the treatment of 10,16 systems becomes different and does not use 0 in the function code.

Six, the function code of borrow deducts true form backward

At this moment allow function code Duo one than true form, enough subtracting. be A98 such as true form, function code is 5EC6,

B446 is working code; During reduction

Among the A980 0 removed, restore true form A98.

Seven, the true form of normal borrow subtracts function code

Take hexadecimal as example, allow true form Duo one than function code, be A1C such as true form, can the merit code be 5BC9

After the variation:

Working code is 4E53 .4E53+BC9 during reduction

After the prefix 5 of 5A1C removed, restore true form A1C.

Eight. the function code of normal borrow subtracts true form

Allow function code Duo one than true form, and many be non-zero position, take hexadecimal as example,

F85 is true form

3E94 is function code.

Obtain working code 2F0F

During reduction

The prefix 0 of 0F85 is removed, obtain true form F85

Illustrate:

1. the addition of normal carry has been declared in " a kind of digital information without logic hardware encryption, decryption method " and has been finished.

2. above-mentioned eight kinds of methods can be alone, and the dynamic use under also can instructing by programming is sent out the instruction module of receiving both sides and taken in memory separately under CPU management separately.

3. various keys are without logically generating, and the length of key is equal to or slightly greater than the length of true form, does not recycle.

4. communicating pair adopts is the stuck-module that keeps in advance, software function is fixed into the effect of hardware, belongs to the category of hardware encryption.

5. the working code that obtains after processing with 2,10,16 systems of same bit information is different, be exactly with after the same function code processing, also obtain different working codes, but as long as reduce according to the former same system that uses man-hour that adds, all reduciblely go out same true form, only affect pilot process, do not affect the result.Give so on the contrary and use what system that the possibility of mobilism is provided, binary system can be described respectively 10,16 systems, and communicating pair can be arranged rear dynamic use system, makes key have more flexibility, randomness, therefore also can improve privacy degrees.

6. above-mentioned true form is being processed when processing and segmentation is being carried out, can be with 1000 bit segment processing binary numbers, 100 digital segment processing decimal numbers, 50 heuristicimal code segment processing hexadecimal numbers; Communicating pair also can be arranged other fragment size, only plays the convenient effect of processing, and the size of segmentation is on the not impact of fail safe of communication.
