It is cached；And using session key and symmetry algorithm name as the key and algorithm of data protection in secured communication channel；It performs
Step S23.
Preferably, in the step S221, if not caching wireless data acquisition terminal certificate, in the step
Increase below scheme between S2221 and the step S2222：Control centre sends control centre's card to wireless data acquisition terminal
Book；Control centre sends the request for obtaining wireless data acquisition terminal certificate to wireless data acquisition terminal.
Preferably, in step s3, the control centre to through safety certification and enter system wireless data adopt
The detailed process for collecting progress data encryption storage and the exchange of terminal imports source data, S32 data intercepts by S31, and S33 systems turn
It changes, S34 character transcodings, S35 data recombinations, S36 character strings are substituted to be completed with S37 shortage of data storage composition, in addition to
Outside step S31 and step S32, other procedural orders can change.
Preferably, in step S32, in the function of interception character, need three elements, i.e., character to be intercepted, interception
Digit and the initial position of interception, source data is character to be intercepted, and the length intercepted is specified, and the initial position value of interception is
By password input by user, data that machine code or server end return split into it is several after all plus 1, the number of fractionation needs
The group number of source data to be imported with plan is identical.
For being intercepted with MID (text, start_num, num_chars) function by bank card password, wherein text tables
Show character to be intercepted i.e. source data, num_chars represents the digit of interception, and start_num is the start bit for representing interception
It puts, num_chars can be specified, when needing upgrading, it is only necessary to source data digit is changed, and reassigns num_chars values,
Such as num_chars values are designated as 20 by 10, then the character intercepted becomes 20 by 10, here it is expand algorithm,
And 6 numbers that bank card can be inputted password by start_num values decouple, the value split adds 1, as start_
Num values intercept character, and method for splitting is relatively more, example MID (password, 1,1), MID (password, 2,1), MID
(password, 3,1), MID (password, 4,1), MID (password, 5,1), MID (password, 6,1), i.e., by 6
Password values become 6 individual characters, for example, in 6 groups of source data first group be denoted as text1, utilize MID
(text1, MID (password, 1,1)+1,20), it is possible to 1 position be added to start with the first bit digital of password password
Text1 is intercepted, intercepts 20, the purpose for intercepting character is that simple data is mingled in complex data, for example, close in bank card
In the design process of code, by this step, password is mingled in source data, after introducing 6 groups of source datas, text values are exactly source number
According to, and start_num values are exactly+1 values of MID (password, A, 1), A is the position of code characters, in this manner it is possible to achieve 6
Group new data, they be the units in having intercepted since the 1st to the 10th num_chars value length data,
For example, the data after password is split are 6, mean that and intercepted since the 7th, num_chars values are 20, mean that the position of interception
Number is 20, and in a simple password 000000 and complicated password 658973, the meaning of the two represents that the former is from 6 sources respectively
The 1st of data starts to intercept, and the latter's expression is from the 7th of 6 source datas, the 6th, the 9th, the 10th, the 8th, the 4th
Position starts to intercept, unrelated with the complexity of password, as long as hardware is not supplied to others by Password Input personnel, and allows simultaneously
Others sees that Password Input acts, and when only being cracked from the password of storage, the difficulty that cracks of the two is not different,
During this step, there are 10 subdatas, that is, password combination number to increase 1,000,000 times for each source data.
Preferably, in the conversion of step S33 systems, if it is desirable, can be by any data conversion into another kind
The data of system, during low binary data is converted into high binary data, since high binary data needs are more basic
Element representation, basic element here is exactly similar 0 to the 9 of 10 systems this 10 numbers, can become fairly simple data
Into complicated data, while data length is shortened, for example cardinar number digital data becomes number and the data of letter mixing, sometimes
It waits, needs complex data becoming simple data or non-numeric data is converted into numerical data.
For example machine code is usually number and alphabetical blended data, and Chinese character is non-numeric data, in GB2312 standards
In, the region-position code of Chinese character can be directly quoted, numerical data is converted thereof into or is understood as GB2312 normative texts
The number (7445 include non-chinese symbol) of 7445 systems, Chinese document is encrypted or applied to digital certificate accordingly, will
Chinese text is understood as 7445 systems, is converted into 10 systems, and data are surprisingly huge, by taking 5 digits as an example, be converted into 10 into
System, digit is up to 20, and peak is 2.2873E+19, and reconvert is into 62 binary datas, that is, is converted into number and letter and mixes
Data are closed, encryption is without using negative data, and therefore, carry is as 10 binary datas and the first power of system number, and two
Power, cube etc. are incremented by successively, and when the digit of programming needs is not achieved in transformed data bits, a high position is supplied with 0
Number, such as transformed 10 binary data are 123, and the digit needed is 5, just adds 0 to supply 5 for 00123 in a high position,
Most people contact English alphabet and number is relatively more, and example is 62 systems and the conversion of 10 systems, with 0 to 9 table of Arabic numerals
Show that 0 to 9, alphabetical small letter a to z represent 10 to 35, alphabetical capitalization A to Z represents 36 to 61, there can also be other designated parties
One's own department or unit code of case, number that aft section is told about or letter, transcoding algorithm is also in compliance with same rule, such as by 62 binary datas
A6bJ9 is converted into 10 binary datas as 36*624+6*623+11*622+45*62+9=533423147, is 9 digits.
Preferably, the character transcoding in step S34 is realized using character transcoding algorithm, with a character or one group
Character is exactly character transcoding by the method that transcoding algorithm obtains another character or one group of character, and either single character is still
One group of character, transcoding are all transcodings one by one, and only the latter is to convert several characters simultaneously, and the transcoding meaning of single character is little
, so being that character group carries out transcoding, character group transcoding needs transcoding algorithm instruction set and transcoding table to realize jointly.
Example is to design four kinds of numbers and the transcoding algorithm of letter, is named as ABCD algorithms, transcoding algorithm follows following rule
Rule：
1：The result is that cannot be identical after the identical algorithm conversion of different source codes；
2：The transformation result of several algorithms of same source code mutually can not be identical；
3：The result of transcoding cannot be identical with source code；
4：Transcoding will set several transcoding algorithms, to strengthen the combinatorial complexity of password,
Example is converted with the basic condition of one's own department or unit of number and letter code, and one's own department or unit code of number 0 to 9 is respectively
Number 0 to 9, one's own department or unit code of lowercase a to z is number 10 to 35 respectively；One's own department or unit code of capitalization A to Z is number respectively
36 to 61.
In ABCD algorithms, wherein the 1st algorithm, the 2nd algorithm, the 3rd algorithm are the mathematics fortune carried out based on the code of one's own department or unit
It calculates, but the 4th algorithm is by manually adjusting, without what algorithm rule,
1st algorithm：The 2nd odd number behind one's own department or unit of number or letter yard plus one's own department or unit code is exactly turn of this number or letter
Code algorithm, as a result >=62, just subtract 62, record the corresponding number of its one's own department or unit code or letter；
2nd algorithm：The 13rd odd number is exactly that this number or alphabetical B turn after number or alphabetical one's own department or unit code plus one's own department or unit code
Code algorithm, as a result >=62, just subtract 62, record the corresponding number of its one's own department or unit code or letter；
3rd algorithm：One's own department or unit of number or letter code adds the transcoding algorithm that 30 be exactly the number or letter, as a result >=62,
Just subtract 62, record the corresponding number of its one's own department or unit code or letter；
4th algorithm：4th algorithm part follow number or letter one's own department or unit code plus the one's own department or unit code after the 3rd even number be exactly
The transcoding algorithm of the number or letter, as a result >=62, just subtract 62, the conflict of the data phase same sex, has done portion in order to prevent
The corresponding number of its one's own department or unit code or letter are recorded in adjustment, from its design principle it is recognised that each before and after transcoding is digital
All will not be identical with letter, this is a most basic designing points, and during calling, the 1st algorithm, the 2nd algorithm, the 3rd algorithm all may be used
It directly to be called using tables of data, can also be converted using mathematical operation, still, the 4th algorithm, which have passed through, to be manually adjusted, and needs to make
It is called with tables of data, other transcoding algorithms can also be designed, exemplary transcoding algorithm is utilized similar field and carries out algorithm
ABCD sorts.
Transcoding algorithm instruction set：Each character to be transcoded needs to instruct transcoding direction that could obtain correctly as source code
As a result, the data of instruction set and data to be transcoded there are correspondence, i.e. an instruction character corresponds to a word to be transcoded
Symbol, by rule is instructed to be converted into another character, for example, instruction set data are BACC, data to be transcoded are 1234, are exactly
1,234 four data are performed into B algorithms, A algorithm, C algorithms, C algorithms respectively.
Preferably, it is to add the one kind that other character substitutes of the partial character in character character string to be substituted in step S36
Secret skill art, replacement can be single replacement or character string substitutes, and preferably designing scheme is that character string substitutes, and is substituted
It is completed using character substitution tables, character substitution tables data are divided into record number and substitute character string, the character that record number occurs
Exactly need the character substituted.
Such as there are 5, A, b, 6 in record number, all 5, A, b, 6 characters all extract in the data that will exactly substitute
Coming, be grouped, the character digit needs after grouping are consistent with record number digit, when last organizes no corresponding digit,
Can abandon substituting or specify increases digit, such as specified first character is added to and meets digit, searches in character substitution tables
Corresponding record number is determined to substitute character string, since the several character original positions extracted are different, be needed
Determine insertion position, more typical method is that the several characters that will be extracted are converted into 10 binary datas, utilizes remainder function
It determines, for example, remainder adds 1 to be several, is just inserted into the original position of which character, the space of other characters is removed, obtained new
Data, the record number design of character substitution tables is it is noted that record number needs to enumerate all combinations being likely to occur, otherwise
It is likely to occur operation mistake, 3 when substituting, needs 27 groups, that is, 3 cube, 4 when substituting, record number just needs
256 groups, be 44 powers, if 5 be exactly 55 powers, up to 3125 groups, thus the number of characters substituted need it is suitable
In, data table data is too huge and too small imappropriate, and alternate data should not be too long, is otherwise possible to by long number it is investigated that finding word
Accord with substitution tables, 4 alternate data only needs 256 groups when substituting, during with English upper and lower case letter and digital representation, one and two
It is sufficient that position, so short data substitute, and just have no idea reversely to find character substitution tables by searching for replacement character string,
Do not allow the character for ciphering process occur or encryption data is not present, this is also for preventing by substituting string searching to word
Substitution tables are accorded with, reason is very simple, if some character only occurs in some tables of data, quickly with regard to that can find, as long as
Character existing for ciphering process or encryption data can serve as substituting character, even the former data character substituted can also go out
It is existing, for example, replacing this four characters of 5, A, b, 6, then, appearance 5, A, b, 6 are still allowed in alternate data, due to the word of replacement
Symbol digit differs, so the digit of final password is uncertain, replacement character may be used superposition encryption method and repeatedly encrypt,
More parts of character substitution tables are designed, connecting data by multiple variables completes repeatedly encryption, such as variable data 2356,6987,
3075,9837,8863,5534, by the sum of 6 groups of data difference divided by character substitution tables, it is connected to corresponding tables of data successively
It completes to substitute, that is, first passes through 2356 and be connected to corresponding tables of data completion replacement, and using the data after replacement as source number
According to, it completes to substitute with the 2nd group of data connection to corresponding tables of data, and so on, character substitution tables have one with homogeneous data table
Point difference, exactly different table record numbers can be different, and refer to that record number digit can also be different, for example, table 1 is
5, A, b, 6 are substituted, table 2 is to substitute c, and 8, H, k or table 1 are completed 3 characters and substituted, and what table 2 was completed is that 4 characters substitute, because
It is the digit and character designed by retrieving record number for program, the character substituted and grouping digit is determined, in programming
In, character transcoding, system conversion and interception character are preferred with obtaining the data of regular length, and after the completion of character substitutes, data
Length is not known, this gives the authorized strength work of the character length contingency table of this step ciphering process of rearrangement character position to bring difficulty,
Although the uncertain length value value of character length contingency table is more random, negative value can not occur, that is, other are determined
The sum of length value cannot be more than the digit of data, be needed after other steps for this purpose, character substitutes this step, shortage of data
Before preservation, otherwise design difficult.
Preferably, the missing algorithm in step S37, when introducing source data by link variable, link variable often has several groups,
Link variable is divided into several groups, and the source data introduced accordingly also has several groups, and link variable group number is very little, and password easily cracks, such as
It is complete that fruit link variable fails record, then, according to the codomain of the data, that is, the value that the data are likely to occur, add successively
It is close, the value consistent with encrypted result can be also obtained, and the number that may be needed and how much related, missing values of the value lacked calculated
When more, it may be necessary to calculation times it is more.
For example, the value range of missing one group of data ABCD, ABCD are all 0 to 9, then, from 0000 to 9999, always all
Matching value can be found, if source data is 6639, then from 0000 operation to 6639, will be obtained as a result, in this process,
10000 operations are at most needed, and if for encrypted as a result, data record is not equally complete, but this infull data bit
Put can be by obtaining, when encryption is compared successively during operation, and actually encrypted result is by these infull characters point
Several sections are cut into, the result of operation needs and this several segment data is all coincide, if encrypted data bits is very long, then,
Occur same password possibility it is also very little, since data record is not complete, from the password of record cracked almost without
May, the missing values for lacking algorithm cannot be too complicated, otherwise slowly obtains less than as a result, the shortcomings that lacking algorithm is and asymmetric calculation
Method is the same very time-consuming, it is not necessary that, it can not use.
Although it as described above, is illustrated according to the embodiment and attached drawing that embodiment is limited, to the art
