ID code
ID code be the instruments such as lung ventilator self with unique authentication coding.Every machine has an ID code, and can not repeat with the ID code of other machine.Hereinafter, for method provided by the invention is more easily understood, use following example to describe: ABCD-EFGH-IJKL
Functional configuration code
Lung ventilator has different types of machines, the function that every kind of type can be realized is also different, and for different type of machines, can not rely on the configuration of specific model and use plurality of optional function, in each machine, the summation of operable optional function item is called function bag.
According to type (namely Configuration Type) and can additionally select to open or the function (namely function bag) of closing, work out a kind of functional configuration code.The end of this code is with two groups of hexadecimal numerical value of two four string representations, and the front two of hexadecimal numerical value represents the Configuration Type of this machine, namely type, the optional function bag that this machine of rear two bit representations is opened, the function of namely having opened.
In the coding of expression Configuration Type, use 8 strings of binary characters to represent 16 system numerical value, from F
1to F
88 strings of binary characters altogether: 00000000 represents whole coding.Wherein, the corresponding numerical digit F of each Configuration Type
i, be F successively from low level a to high position
1-F
8.Can be arranged to as known to the skilled person the numerical value of each, numerical value 1 represents "True", and numerical value 0 represents "No".For example corresponding first F of Configuration Type 1
1, use 00000001 expression, be converted into 16 systems and be 01.The corresponding second F of Configuration Type 2
2, represent with 00000010, be scaled 16 systems and be 02.Corresponding the 3rd F of Configuration Type 3
3, represent to be scaled 16 systems with 00000100 and be 04, by that analogy.Finally in Configuration Type coding, by the Configuration Type coding with this 16 system numeric representation lung ventilator.
Function code also uses similar coded system, uses 8 strings of binary characters to represent 16 system numerical value, is followed successively by E from low level a to high position
1to O
8, totally 8, every kind of corresponding numerical digit of optional function item, numerical value " 1 " represents "True", namely opens function corresponding to this numerical digit; Numerical value " 0 " represents that "No" namely closes function corresponding to this numerical digit.The for example corresponding E of optional function 1
1, code 1 use 00000001 of opening this function represents, being scaled 16 system numerical value is 01; The corresponding numerical digit E of optional function 2
2, the code of opening this function represents with 00000010, being scaled 16 system numerical value is 02; The corresponding numerical digit E of optional function 3
3, the code of opening this function represents with 00000100, being scaled 16 system numerical value is 03, by that analogy.If select to open multiple functions, the numerical digit corresponding to these multiple functions be set to respectively to 1 simultaneously simultaneously, for example, the optional function bag of machine is function 1 and function 3, namely this machine has been opened function 1 and function 3, as mentioned above, represent with binary code 00000101, being scaled 16 system numerical value is 05.By that analogy, final in functional configuration code the function code using this hexadecimal numerical value as this lung ventilator.
It should be noted that hexadecimal numerical value double figures used herein represents, if two of less thaies, in a high position with 0 polishing, to encode in the time forming functional configuration code.
Therefore, as above, machine ID code is ABCD-EFGH-IJKL, and type is Configuration Type 2, uses binary coding representation 00000010, is converted into hexadecimal Configuration Type and is encoded to 02; Here take the additional function bag of this machine as optional function 2 and optional function 3 describe as example, opening the binary coding that this function bag is corresponding is 00000110, being scaled hexadecimal function code is 06; Obtaining like this function code is 0206.
Above ID identification code and function code are combined according to sequencing, obtained functional configuration code: ABCD-EFGH-IJKL-0206.
From above-described example, can learn, use encryption method provided by the invention, can in coding, comprise multiple Configuration Types and multiple optional function.For example use eight-digit binary number string representation, can be up to 16 kinds of Configuration Types and the 16 kinds of optional functions that can open.
Below the cryptographic algorithm using in the present invention is described.
Out of order arthmetic statement
As well known in the skilled person, the coding of machine adopts digital 0-9 and English alphabet A-Z totally 36 character compositions.In out of order algorithm provided by the invention, the ASCII character of numeral and English alphabet is arranged in to a table of comparisons by ASCII character by the order increasing progressively, and as First ray table, in table, the order of ASCII character is: 48-57,65-90, difference corresponding digital 0-9 and English alphabet A-Z successively.
Above First ray table is rearranged, obtain at random new array, only describe array 1:55,90,52,53 herein using array 1 as the random one group of ordered series of numbers producing as example, 54,56,57,73,65,67,68,69,48,70,71,86,72,84,74,88,89,75,51,76,77,78,79,50,80,81,49,82,83,85,66,87.This array 1 is one and encrypts operator, and this encryption operator produces at random for each lung ventilator, and is stored in this lung ventilator, and the encryption and decryption of multiple codings that this lung ventilator is produced are all used the encryption operator of this lung ventilator.
For the character string that will encrypt, for the character Ci of each numerical digit, first in First ray table, find out the position P of Ci
ci, then read in the P in array 1
cilocational ASCII character A
pci; Return in First ray table, read A
pcicorresponding character CA
apci, by this character CA
apcias encrypt after character string at position P
cion character.
For example, in character string 0123ABCD, primary character is 0, i.e. C
1=0, in First ray table, 0 position P
0at the 1st, namely P
0=1; Then on the position 1 in array 1, read ASCII character, A
1=55; Return in First ray table A
1the character CA that (namely ASCII character 55) is corresponding
55=7; , after current encryption, the character of the 1st of encrypted characters string is C
1'=7.Equally, the 2nd of character string the character C
2=1, in First ray table, 1 position is at the 2nd, namely P
1=2; In array 1, the ASCII character of the 2nd is 90, namely A
2=90, get back in First ray table the corresponding character Z of ASCII character 90, namely CA
90=Z; Like this, in the character string after encryption, second character is C
2'=Z.By that analogy, the 8th C of character string
8=D; The position P of D in First ray table
d=14; In array 1, the digital A on the 14th
14=70; Get back in First ray table the character CA of ASCII character 70 correspondences
70=F; Therefore after encrypting, the 8th character of character string is C
8'=F.According to above method, character string 0123ABCD is encrypted, the result of encryption is: 7Z45DE0F.
Like this, after string encoding, allow user just can not identify original character string, reach the effect of encryption.In the encryption method process of the following stated, all use this cryptographic algorithm to describe for example as the part of ciphering process.
Encrypted code
Encrypted code is kept in product individuality, the character string that the functional configuration code being made up of ID code and function code calculates through cryptographic algorithm.Functional configuration code ABCD-EFGH-IJKL-0206 as in the example above of example, the encrypted code obtaining after using above-mentioned encryption operator once to encrypt is: 56TD-H00W-ENKG-1R46, is the encrypted code in this lung ventilator.
Described encrypted code is kept in the middle of each lung ventilator, in the time of each startup lung ventilator, system reads this encrypted code, be decrypted according to the decryption method corresponding with above-mentioned encryption method, obtain the real functional configuration code of above-described this product, thereby according to the corresponding function in the information operation lung ventilator in this functional configuration code.
In addition, configuration code is encrypted and is obtained in the process of lung ventilator configuration code, first, system need to read this encrypted code, and anti-deciphering obtains real functional configuration code, re-uses afterwards above-described encryption method and is encrypted.
Configuration code
Configuration code is encrypted and obtains above-described functional configuration code, configuration code is sent to supplier by user, supplier deciphers configuration code, obtain real functional configuration code and can learn the ID code of lung ventilator, type (namely Configuration Type) and the function bag (function items of namely having opened) having selected.In the time that user need to open the optional function in lung ventilator, the first current configuration code of read machine from lung ventilator, and the configuration code of reading is informed to manufacturer.
The concrete generation step of configuration code is: produce at random the numerical value between 0 – 99 as the first encryption number of times, functional configuration code is encrypted, repeat this encryption number of times, obtain the first encrypted code; The first encryption number of times of above-mentioned generation is attached to the end of the first encrypted code; Carry out Standard Encryption one time, what obtain is exactly described configuration code again.Specifically describe as an example of above-mentioned functional configuration code ABCD-EFGH-IJKL-0206 example.The random encryption number of times producing is take 12 as example, and, to functional configuration code encryption 12 times, the result obtaining is GJTV-A505-J6SW-KR1U.The first encryption number of times is directly increased to coding ending, obtain GJTV-A505-J6SW-KR1U-12, carry out Standard Encryption one time to having added first the first encrypted code of encrypting number of times, final result is GQBU-5MXD-DR0S-PJH3-RJ, is the configuration code that user reads from lung ventilator again.In this embodiment, use ten's digit 12 to describe as example, it may occur to persons skilled in the art that, can also represent to encrypt number of times by the numeral of other systems such as hexadecimal.
Like this, this configuration code can make a distinction with above-mentioned encrypted code, and has increased and crack difficulty.While reading this configuration code due to user, all produce at random one first at every turn and encrypt number of times, therefore make all differences of configuration code that at every turn read; In ciphering process, the first described encryption number of times is increased in the first encrypted code, form a part for the first encrypted code, be encrypted again, after making this configuration code once decipher, can obtain the first encryption number of times, be decrypted and can obtain real the first functional configuration code of lung ventilator according to this first encryption number of times.
Registration code
The coding that registration code provides for user according to user's requirement for manufacturer, the information comprising in this coding has the unique identifier of machine, namely ID code, the Configuration Type of this machine, and the function of this machinery requirement realization.Machine, by reading the functional configuration code of corresponding information in this registration code, can be upgraded to the type of needs and function, opens or close corresponding software function.
The cipher mode of registration code is similar to the cipher mode of configuration code, and the difference of the two is encrypted code to add the position difference in the first encrypted code, has further strengthened the level of encryption of registration code and the difficulty being cracked.In the ciphering process of registration code, except random generation second is encrypted number of times, also numerical digit I is inserted in one of random generation, the second encryption number of times is inserted to the position of the random number I in character string, and insertion position I is recorded in to the end of the second encrypted code character string.Concrete mode is as follows: the truth function configuration code of machine is: ABCD-EFGH-IJKL-0206.Get the random value of 0 – 99 as the second encryption number of times, same, for example get 12, the truth function configuration code of machine to be carried out to 12 times and encrypt, result is GJTV-A505-J6SW-KR1U, describes here using this result as the second encrypted code.Afterwards, get the random value of 0-15 as insertion position I, for example I=1, the 1st at the second encrypted code inserts the second encryption number of times 12, and this insertion position I=1 is attached to the end of the second encrypted code, and result is G12J-TVA5-05J6-SWKR-1U01.The result obtaining is carried out to Standard Encryption again one time, even carry out once out of order encryption with above-mentioned encryption operator, result is: XRVU-W6HN-7GWZ-0166-QWTR.
As what can find out from above example, insert position and represent with double figures too, the supplying with 0 in a high position of two of less thaies.And because carrying out the configuration code of example in this specification is 16, therefore, the insertion position I selecting, between 0-15, is understandable that, if the configuration code figure place of encoding is more, can select wider numerical value to produce this insertion position herein.
Decoding
As the skilled personnel can understand, using above-described method to be encrypted, after producing configuration code or registration code, can use identical method in reverse order this coding to be decoded through the configuration code of encryption or the recipient of registration code.For example, after receiving configuration code, first use encryption operator and above-described ASCII character and the First ray table that numeral and English alphabet contrast once to decipher, obtain containing and encrypt number of times or encrypt number of times and the coding that inserts bit digital; By this encryption number of times or encrypt number of times and depart from from coding with inserting together with bit digital, remaining coding is decrypted according to encrypting number of times, finally just can obtain original configuration code or the registration code that machine can read and identify.
Direct beneficial effect of the present invention is that encrypted code is unique, due to using the unique identifier of each product as a part of encrypting, therefore can not produce the identical situation of encrypted code of two products.Meanwhile, adopt the cipher mode of encrypting operator to make the effect of encrypting obtain duplicate protection, unless the particular content of cryptographic algorithm and operator are revealed simultaneously, otherwise be difficult to crack.In addition,, because the Configuration Type to each product and function choosing-item are as a part for encrypted code, therefore every product uses a password can control the unlatching of all functions or close.
Be understandable that the unique ID of above-described machine can also use the coding that other can unique this product of sign, unique sign such as unique ID, unique physical address of network interface card of such as CPU.
Algorithm expansion
Above-described out of order algorithm is inquired about according to the ASCII character array of rearrangement.Be referred to as out of order table here, encrypt operator.Because the order of encrypting operator is random alignment, therefore we can use multiple different encryption operators, and character string is repeatedly encrypted.Encrypt operator for each, also can repeatedly encrypt.Meanwhile, such as, character in the coded string (functional configuration code etc.) that can encrypt needs do the operation of resequencing simultaneously, such as the reach of each character position or after move.According to this kind of mode, can encrypt different results to same character string.
The present invention has used the mode of encrypting operator to be encrypted calculating.As mentioned above, each encryption operator is random generation, and the character string sequence of the encryption operator using while therefore encryption is all not identical.Also can not use encryption operator to be encrypted, but directly solidify a character string sequence of upsetting in algorithm, can realize equally identical effect, the intensity of just encrypting has been lowered.
The present invention can be applied to Anesthesia machine equally, on the electronic equipments such as patient monitor.Cryptographic algorithm itself is applicable to the application that all character types are encrypted simultaneously.
Note, above are only preferred embodiment of the present invention and institute's application technology principle.Skilled person in the art will appreciate that and the invention is not restricted to specific embodiment described here, can carry out for a person skilled in the art various obvious variations, readjust and substitute and can not depart from protection scope of the present invention.Therefore, although the present invention is described in further detail by above embodiment, the present invention is not limited only to above embodiment, in the situation that not departing from the present invention's design, can also comprise more other equivalent embodiment, and scope of the present invention is determined by appended claim scope.
