Description

The Chinese international code " compressed code type " communication coding method

The present invention belongs to a kind of means of communication that computing machine realizes that in communication field Chinese and western languages is rationally compatible and communicate with code telegram.

At present, most in the world computing machines all are the IS0646 codings of adopting international standards, and it is to carry out the function agreement so that the American Standard Code for Information Interchange of seven communication coding modes is next with system software.When actual communication, owing to it carries out with the alphabetic writing array mode, so be also referred to as the western language mode.And Chinese character combines with spell shape, therefore obviously be not enough as directly coming the defined Chinese characters coding with the byte American Standard Code for Information Interchange, so JIS JISC6226 coding and CNS GB2312-80 coding regulation, all seven codings with double byte come the defined Chinese characters coding, but because the double byte encode Chinese characters for computer is topped, all print character collection of AScII code have been overlapped, and in the middle of the print character collection of American Standard Code for Information Interchange, have more symbol code and system software that special function agreement is all arranged, therefore, in prior art, in order on the computing machine of western language communication modes, to reach the purpose that Chinese character communication is handled, all expanding system software to be revised earlier, Chinese character communication could be realized then.At home the version " Chinese information " in 1984 opening number magazine, talked about how on the English digital disposal system, to realize several expansion amending methods that Chinese character is handled, and how compatibling problem also need be analyzed and researched to have mentioned Chinese character information processing and English digital system in " meaning and the category of Chinese character information processing research " literary composition that woods East Sea author writes.Obviously this technical barrier is not also broken through.In system communication and system software, how to distinguish problem about AScII sign indicating number and Chinese character international code, in " superficial view of higher level lanquage and Chinese character information interface " literary composition that in 1984 the tenth diligent river authors of first phase king of " reasonable plan of Chinese-English information handling system " that " Chinese information " in 1985 second phase Wang Wei's intelligence author writes literary composition and " computer engineering and application " write, two kinds of define methods have been mentioned to Chinese character international code, a kind of is to be set to " 1 " in the Chinese character international code most significant digit, abbreviates eight communication modes as.Another kind is that each Chinese character is resolved into three bytes, and the first, the three byte represents that with A to Z second byte is represented with 0 to 9, to reach the differentiation of encode Chinese characters for computer and ASCII character.Can find in actual use, do not separate owing to having obviously between digit that in the encode Chinese characters for computer of three byte definition modes, also contains American Standard Code for Information Interchange and the defined encode Chinese characters for computer, therefore in Chinese and western languages mixing communication, also all under cover in in, or in the coding ambiguity in west, having a strong impact on the security and the reliability of system resource.Moreover, for in some, the system software of mainframe computer, owing to itself all lock, encryption function, thereby greatly limited the hack of user to system software, therefore depend merely on the method for revising system software and just be difficult to realize Hanzify, this just China also have many computing machines not have the main cause of Chinese character processing capacity as yet so far why.

One of purpose of the present invention is the deficiency that exists in the prior art in order to solve, and has proposed a kind of realization Hanzify method of novelty, and system software is not done any requirement, only by Chinese character international code being carried out reasonable conversion, can realize Chinese character communication.Invented a kind of compression method that Chinese character international code is had the tracking Control function, it is transparent fully that this compression method can make encode Chinese characters for computer realize in system software for this reason, in Chinese and western languages mixing communication is handled, reaches compatible fully with original system software.So both avoided modification, solved the ambiguous problem of various codings again, and made the Chinese character compressed code can be the same, may penetrate into each corner of system software, whole resources of shared system with the western language character string to system software.Make the Chinese character peripheral hardware as the western language peripheral hardware, utilize communication interface directly just can carry out Chinese and western languages mixing communication freely, thereby also rationally solved how this difficult problem of compatibility of Chinese character information processing and English digital system with host computer system is convenient.

Two of purpose of the present invention, exactly in order to make the computer Chinese-character information disposal system can be used for office's office safely, business administration, the military combat commander, the various aspects that information transmission etc. need secure communication to handle, therefore, on the basis of Chinese character international code being compressed processing and addition the function of communicating with code telegram, the selection that is available for users in communication, Chinese character information be had plain code or two kinds of modes of password.

The present invention has the compression method of tracking Control function about Chinese character international code, its principle is: observing under the standardized prerequisite of communication coding, the area code of Chinese character international code, item double byte code is by compression, make it to be mapped in ascii character-set and system software and do not have the character zone of special agreement and user in A to the Y code set that English capitalization that conversational communication or english writing seldom use or capital and small letter intersect, and has a function of tracking Control, as long as system needs in communication, at any time all can be reduced into Chinese character international code to Chinese character compressed code, to guarantee the standardization of communication coding.In Chinese and western languages mixing communication, the differentiation of Chinese character compressed code and western language character string, and the conversion work of Chinese character compressed code and Chinese character international code are discerned by the Chinese character peripheral hardware and to be finished.

Cryptographic function of the present invention is with solving the safety of user's Chinese character information, privacy problem, and the generation of password is to utilize Chinese character international code in compression process, owing to can compress from different approach, and can obtain the product of identical result.Itself combining of the formation of Chinese character international code by the two-dimensional matrix double-byte encodings, each Chinese character can have the compression parameters of ten constricted zones available, and ten constricted zones can be formed full an arrangement, the compression control sign indicating number also is to adopt the two-dimensional matrix definition, can form different arrangements again, so this provides advantage to setting up the cipher key card, by statistics, the cipher key card adopts the hash combinational algorithm to produce kind can reach 4.95912 * 10 ¹⁵Kind, in every cipher key card, can also provide 25 kinds of dynamic passwords, can set up double code for the user, in actual use, not only between the Chinese character peripheral hardware different communicating with code telegram can be arranged, and in same Chinese character peripheral hardware reaches with a cipher key card, also can set up the cryptogram of different stage separately, to satisfy user's different demands.

The Chinese character international code of using only is a baseset at present, about 8,000 Chinese characters, and be far from being enough in actual applications, so the Chinese character supplementary set that State Bureau of Standardization is about to issue is that ASC II code Single-Byte Character Set is arranged, the Chinese character basic character set, Chinese character first supplementary set, Chinese character second supplementary set, Chinese character the 3rd supplementary set, total total N character set form, but the selection between them all defines with functor, so must bring a lot of troubles in actual use from now on.The present invention is directed to different computer systems for this reason and propose two kinds of different optimum implementation.

Fig. 2 is that national standard Chinese Character Set Code for Informati supplementary set calls synoptic diagram.

First kind of scheme:

Be primarily aimed at system software and in communication, allow to accept the system that English capital and small letter character is handled, adopt the implicit method that is provided with to determine each Chinese character supplementary set.Chinese character international code is mapped in English capital and small letter A to the Y code by intersecting after compressing again, replace functor by implicit the setting, this has also play a part two to get at one stroke to Chinese character compressed code, make the both implicit Chinese character supplementary set of having determined, solved the differentiation with the English character string again, thereby to the identical nybble set-up mode of still using with baseset of set-up mode of Chinese character supplementary set.

Each supplementary set of Chinese character compressed code is implicit be provided with as follows:

A≤α≤y α≤β≤y F ₁=Chinese character preamble code

Chinese character set type 1	Functor
		(Chinese character baseset compressed code)=(F 1α α α) (Chinese character baseset compressed code)=(F 1α β α) (Chinese character baseset compressed code)=(F 1β β β) (the auxilliary collection compressed code of Chinese character)=(F 1β α β) (the auxilliary two collection compressed codes of Chinese character)=(F 1β β α) (the auxilliary three collection compressed codes of Chinese character)=(F 1 βαα）	GOINGOINGOINSO(GIIN)SS2(LS2)SS3(LS3)

Along with the progressively promulgation of State Bureau of Standardization to other Chinese character supplementary set, method of the present invention still can continue implicit the setting.

In actual communication, all functions of the present invention all are inserted in the Chinese character peripheral hardware and realize in the communication device of the present invention.Now hypothesis has a computing machine to need to carry out the Chinese character on-line communication with a Chinese terminal, the communication that the system software that computing machine disposed allows to accept English capital and small letter code is handled, in the communication device of the present invention that on Chinese terminal, is inserted, the Chinese character preamble code is dynamically arranged with English capitalization Z code, Chinese character set is appointed as baseset, dynamic password is set to 3, and the form that compression parameters address table and key card are provided with is as follows:

Wherein the division of Chinese character area code, ten constricted zones of item and each regional sequence number password setting are as follows:

This function allows the selection of password and two kinds of communication modes of plain code in communication, and existing hypothesis has " patent of invention " four Chinese characters to need from the Chinese terminal input and passes to computing machine, and then passes to the Chinese terminal demonstration from computing machine.Communication modes is selected as follows:

First kind, the mode of communicating with code telegram:

Chinese character string is by keypad or the big keyboard input of certain input mode from Chinese terminal, and what obtain is Chinese character international code.Its Chinese character international code numerical value of " patent of invention " four Chinese characters is 55,34 67,119 87,40 64,123.Be shown as with ASCII printing symbol: 7 " CwWC@, obviously comprising ASCII numerical code and symbolic code in these four Chinese characters, as not conversion, that ambiguous generation of encoding just is difficult to avoid, and existing the need is transformed into Chinese character compressed code to Chinese character international code, and execution in step is as follows:

The first step: the area code sign indicating number 55 that the taking-up Chinese character international code " is sent out " judges that belonging to second compression zone adds that compression parameters 22 forms Chinese character area code compressed codes 77, and the password sequence number is 5.

Second step: the item sign indicating number 34 that the taking-up Chinese character international code " is sent out " judges that belonging to first compression zone adds that compression parameters 32 forms Chinese character item compressed codes 66, and the password sequence number is 4.

The 3rd step: learn that from Q unit-1 status code the compression control sign indicating number is being listed as capable control mode, calculates by compression control sign indicating number composite formula:

The compression control sign indicating number=(j-1) * 5+i+64 i=4 j=5

＝（4-1）×5+5+64

＝84

The 4th step: taking out the dynamic password value from the N unit is 3, thereby needs the compression control sign indicating number is encrypted once more, and the double-encryption compression control code value that calculates through the encryption formula is 87.

The 5th step: taking out the Chinese character set status code from the W unit is 0, is defined as baseset, should represent with English lower case by supplementary set implicit difiinition regulation Chinese character area code compressed code, thereby to need add 32 values of obtaining to Chinese character area code compression code value 77 is 109.

By above-mentioned five steps processing Chinese character international code " sending out " is transformed into Chinese character compressed code, Chinese character preamble code Z in the assembly, be shown as with ASCII printing symbol: ZWmB, " patent of invention " four Chinese characters form Chinese character compressed code with this circular treatment: ZWmB ZIcG ZLmH ZXlK, and passing to computing machine, computing machine sends to Chinese terminal again and shows when receiving input.Need during display process Chinese character compressed code is transformed into Chinese character international code, execution in step is as follows:

The first step: judge that one by one the English character string still is the Chinese character compressed code string receive the Chinese characters of four bytes compressed code of " sending out " at Chinese terminal after, after judging the genus Chinese character compressed code, remove the implicit setting of supplementary set earlier, Chinese character area code compressed code 109 is deducted 32 obtain Chinese character area code compressed code true value 77.

Second step: remove dynamic password, the compression control code value 87 of double-encryption, through deciphering formula value of calculating 84.

The 3rd step: the constricted zone password sequence number of trying to achieve Chinese character area code, item with row row compression control sign indicating number decomposition formula.

j＝INT〔（I-65）/5〕+1

＝INT〔（87-65）/5〕+1

＝5

i＝MOD（I-65，5）+1

＝MOD（87-65，5）+1

＝4

The 4th step: the password sequence number 4 with Chinese character item compressed code is taken out compression parameters value 32 from the cipher key card, Chinese character item compressed code 66 is deducted 32 obtain Chinese character item GB true value 34.

The 5th step: the password sequence number 5 with Chinese character area code compressed code is found corresponding compression parameters value 22 from the cipher key card, Chinese character area code compressed code 77 is deducted 22 obtain Chinese character area code GB true value 55.

By above-mentioned five steps processing, the Chinese character compressed code conversion has been reduced into Chinese character international code, can show Chinese character image at the Chinese terminal screen.

Second kind, the plain code communication modes:

Chinese character plain code communication processing mode and Cipher Processing mode are identical, just more simplified, compression control sign indicating number ranks control mode, dynamic password need not, the Chinese character area code, each five constricted zones ordering of item is identical, compression parameters is identical, area dividing is identical, and the password sequence number just replaces with the constricted zone sequence number, thereby handles just very convenient.The division of plain mode Chinese character area code, item constricted zone is defined as follows:

Second kind of scheme:

Mainly be in communication, only to allow to accept the English capitalization code at system software, do not accept english lowercase, even some system has accepted the english lowercase code, but when exporting in system, still change English capitalization output into, therefore in these communication environments, just can not imply the Chinese character supplementary set is set with English capital and small letter interleaved mode, for this reason, the present invention proposes a kind of implicit Chinese character supplementary set method that is provided with of six bytes, be chosen in and use probability minimum in the English character string, and the English capitalization Z that does not belong to the Chinese character compressed code range of definition again is used for defining the alignment code of each supplementary set, the alternative functions symbol.Like this in the Chinese character compressed code of six bytes because the insertion of English capitalization Z also can reach tangible differentiation with the English character string, with the correctness of guaranteeing that the two kinds of codings in Chinese and Western mix communication.

Six bytes define each Chinese character supplementary set location map

{ Chinese character compressed code }={ Chinese character preamble code, compression control sign indicating number are distinguished a compressed code, distinguish two compressed codes, position one compressed code, position two compressed codes }

{ Chinese character preamble code }=F ₁A≤α≤Y

{ Chinese character baseset compressed code }={ F ₁, α, α, Z, α, Z }

{ the auxilliary collection compressed code of Chinese character }={ F ₁, α, α, Z, Z, α }

{ the auxilliary two collection compressed codes of Chinese character }={ F ₁, α, Z, α, α, Z }

{ the auxilliary three collection compressed codes of Chinese character }={ F ₁, α, Z, α, Z, α }

The execution of six byte communication modes and nybble communication modes are identical, just when each Chinese character supplementary set is set, by district, the item position that each Chinese character supplementary set distributes, imply definite with zee implicit.

Advantage of the present invention is conspicuous by top narration, compared with the prior art its good effect is, the present invention has explored the approach of the realization Hanzify of a novelty, not to realize Hanzify by revising system software, be transformed into and the on all four Chinese character compressed code of English character string but utilize the Chinese character peripheral hardware that the Chinese character international code of keyboard input is handled through overcompression, and appear in the system software with having no conflict, thereby reached dexterously and do not revised system software, just can realize the purpose of Hanzify communication, so just no longer exist the problem of computing machine requirement Hanzify.As long as the most novel various computer systems are mixed the Chinese character peripheral hardware, can have software development, the application of Chinese character processing capacity.Thereby shortened the computer Chinese-character information lead time, improved efficient, adapted to that the computing machine renewal " is maked rapid progress " and software development is the development trend of " blast " speed.Compatibling problem to Chinese character and English digital system has also obtained reasonable solution simultaneously, and has avoided the ambiguous problem of various codings.The character cipher mechanics of communication is not seen report at home as yet, compare with U.S.'s DES cryptographic algorithm of in the computing machine communication, using always in the world, because the DES Cipher Processing is to liking byte western language sign indicating number, therefore variation range still is limited, the full cryptographic algorithm complicacy of leaning on reaches the encryption purpose, and being exactly the double byte two-dimensional matrix, encode Chinese characters for computer itself combines, key is again the cipher key card that utilizes the pre-service of ten compression parameters by the hash combinational algorithm to produce, its variation range is far longer than the DES password, through comparing, this cryptographic function has encryption, decryption processing is easy, speed is fast, and the password key changes the kind complexity, the characteristics that are difficult to decode.Chinese character communication is furnished with the different demands that cryptographic function can satisfy various applications.Therefore the present invention will produce good effect in computer Chinese-character information process field and information communication field.

The present invention designs definition at the used ASCII character communication environment of most computer systems, but also applicable to the EBCDIC communication code.Its embodiment is to Japanese JISC6226 coding and Chinese Minority Nationalities literal code, and every literal with the spell shape array mode all can directly use, thereby will produce bigger economic results in society.
