Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, right below in conjunction with drawings and examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
An embodiment of the present invention provides a kind of methods of software upgrading verification.The method of software upgrading verification is used for network
Server side.As shown in Figure 1, the flow chart of the method for the software upgrading verification of the embodiment of the present invention.The specific mistake of this method
Journey is as follows：
Before the software is verified in upgrading, this method includes following process：
Step S10：Store the sequence number of the software.
In general, after the product (such as CD, flash memory etc.) for the carrying software that completes, network server can be pre-
The sequence number for first storing the software, so that whether the sequence number that subsequently can detect software input by user is correct.On each product
The software of carrying has different sequence numbers, and the software carried on the sequence number of the software and each product uniquely corresponds to.
The sequence number of the software can be by being attached to the packaging of product or being documented in the modes such as specification so that user knows the software
Sequence number.
Step S20：Activate the software, preserve the hardware ID for the hardware for installing the software, and by the sequence number of software, authorize
Password and hardware ID binding.
User by the software installation on hardware after, can by way of being inputted on webpage by the sequence number of software, award
Power password, hardware ID etc. are sent to network server, so that network server activates the software on the hardware and preserves the hardware
The information such as hardware ID.During activation, network server can also record the time for activating the software.
Hardware ID is the ID number of energy one machine of unique mark.Software includes system centre, server client, common
Three modules of client, the hardware ID described in technical scheme of the present invention refer to the machine for being mounted with system centre module
ID number.
When user is after buying software, software can be obtained by searching or reading the modes such as specification in packaging sequence
Row number.
Licencing key is user-defined character string.Character in the character string can be capitalization, lowercase,
Numbers and symbols etc..Under normal circumstances, network server can limit the length of licencing key and define the group established practice of its character
Then, for example, the length that can limit licencing key is 6, the character for forming licencing key can only be 1~9 number.
The hardware ID is generated by following process：
(1) Disk Serial Number is obtained.
The Disk Serial Number is the first character group being made of character.The Disk Serial Number is typically chosen system disk or peace
Fill the sequence number of the disk of the software.The character can be capitalization, lowercase, numbers and symbols etc..Preferably,
The length of one character group is x bytes.For example, the length of the first character group is 20 bytes, the first character group is #
123456789abcdeABCDE。
(2) it exchanges the position of two characters adjacent in the first character group to form the second character group.
The step can exchange the position of the adjacent character of any two.Preferably, exchange rule in the position is：From
The first character of one character group starts, and with two adjacent characters for one group, the position of two characters in one group is carried out
It exchanges.For example, after preferably exchanging rule using this, the first character group #123456789abcdeABCDE becomes the second character group
1#32547698badcAeCBED。
(3) partial character of the second character group is subjected to character filtering.
Character filtering can be filtered according to certain rule, to which the character for not being inconsistent normally is replaced with other words
Symbol is to realize the filter process of character.
Preferably, the step of character filtering can be carried out according to following process：
(a) judge whether the preceding x character of the second character group is character in standard character group one by one.
The standard character group can arbitrarily be defined by network server.For example, the character in the standard character group includes：a
~z, A~Z and 0~9, that is to say, that when character is any character in a~z, A~Z and 0~9, which is standard word
Symbol.For example, according to the definition of above-mentioned standard character, in addition to character " # " in the second character group 1#32547698badcAeCBED,
He is standard character entirely.
Wherein, o<x≤m.For example, when x is 8, then preceding 8 characters of the second character group need to be only judged.
(b) character being not belonging in the preceding x character of the second character group in standard character group preset characters are replaced into shape
At filtered partial character.
There is no limit can be capitalization, lowercase, number, symbol etc. to preset characters.For example, the second character
Second character " # " is then replaced with K by group 1#32547698badcAeCBED when preset characters are K, and x is 8, filtered
Partial character is 1K325476.
(4) using filtered partial character as hardware ID.
For example, the above-mentioned filtered partial character 1K325476 is as hardware ID.
The generating process of the hardware ID obtains new character group by specific method filtering characters and is used as hardware ID, can
To improve the safety of subsequent upgrade verification process, the risk that hardware ID is cracked or usurps is reduced.
Step S30：Generate authority.
As shown in Fig. 2, step S30 specifically includes following process：
Step S31：Software information is obtained according to the sequence number of software.
Preferably, which includes：The system centre section that the type of the sequence number of software, the sequence number of software are bound
The upgrading for the client node number, software that points, the server node number of sequence number binding of software, the sequence number of software are bound
The term of validity.
Wherein, the type of the sequence number of the software includes：Trial edition sequence number, ordinary enterprises version sequence number and high-level enterprise
Version sequence number etc..
The software information can be at least one of above- mentioned information, can also be a variety of combinations in above- mentioned information.
When the software includes simultaneously three system centre, server, client modules, then the software information can be simultaneously
The sequence of the server node number and software of the sequence number binding of the system centre number of nodes, software of sequence number binding including software
The client node number of row number binding.
The software of one binding sequence number has just been bundled with serial number type, system centre number of nodes, clothes when selling
The information such as business device number of nodes, client node number, the upgrading term of validity will obtain these information and only need to inquire database.
Step S32：The version information of software information, the sequence number of software and software is generated into the first character string.
Above-mentioned version information includes the date of software publication.The statement of date may be used in the date of software publication
Form is denoted as XXXXXXXX, wherein first 4 are year, and and then two are the moon, and last two are day.Such as the date of issue of software
Phase is on 2 27th, 2007, then the version information is denoted as 20070227.
The step can be by writing the version information of the sequence number of software information, software and software in a certain order
Enter in output buffer and obtains.The generating process is the state of the art.Output buffer refers to a fritter of computer
For storing the memory of data.It is of course also possible to these character string informations are not written into output buffer, but with any one piece
Memory field stores, and can do subsequent operation.Can be below when output buffer is written in above-mentioned character string information
File output prepare.
The character of first character string is number, lowercase a~z and capitalization A~Z.Such as first character string be
1234567。
Step S33：The first character string of part is intercepted since the first character of the first character string.
The length of the first character string of part of interception is unlimited, but the length should be less than the total length of the first character string, and big
In 0.Such as the first character string of part of interception is 1234.
Step S34：The first character string of part that interception is replaced with the second character string obtains third character string.
The length of second character string is N byte.The length of second character string and the first character string of part of interception
Equal length.Second character string is customized character string.The character of second character string is for digital, lowercase a~z and greatly
Write female A~Z.For example, the second character string is customized for 4321, then the length N of the second character string is 4 bytes, replaced
Third character string is 4321567.
Step S35：By N+1 character A in third character string to the word of the third character string in a last character
Symbol replaces with new character successively, obtains the 4th character string.
Wherein, step S35 specifically includes following process again：
(1) by the length N of the second character string of subscript modulus of N+1 character A in third character string, the first number is obtained
Value n.
Lower target meaning in the present invention is：When character A is N+1 characters, N is designated as under character A.
Wherein, the subscript that the result of modulus is character A divided by the remainder that N is obtained.
For example, the length N of the second above-mentioned character string is 4, then the 5th in third character string character A is the 5, the 5th word
4 are designated as under symbol A, the first numerical value n is 0.
(2) (n+1)th character B of the second character string is obtained.
For example, when the first numerical value n is 0, then the 1st character B in the second character string 4321 is 4.
(3) character B is converted into binary number b.
For example, when character B is 4, binary number b is 100.
(4) character A is converted into binary number a.
For example, when character A is 5, binary number a is 101.
(5) binary number b and binary number a are subjected to step-by-step xor operation, obtain numerical value c.
For example, above-mentioned when binary number b is 100, binary number a is 101, and the numerical value c obtained after step-by-step xor operation is
101。
(6) numerical value c is replaced to N+1 character A of third character string.
For example, the 5th character A in third character string, i.e. number 5, are replaced by 101.
(7) above process is recycled until the last character in third character string is replaced.
For example, for above-mentioned third character string be 4321567, recycle above-mentioned process, then will use step (1)~
(6) character 6 and 7 in third character string is replaced successively, then it is as follows specifically to replace result：
It is designated as 5,5 under 6th character 6 and obtains the first numerical value n by 4 modulus to be 1, binary number a is 1, the second character
The 2nd character B in string is 3, and binary number b is 11, then the numerical value c that step-by-step exclusive or obtains is replaced by for 10, final 6
10。
6 are designated as under 7th character 7, is 2 by 4 modulus, binary number a is 10, the 3rd word in the second character string
It is 2 to accord with B, and binary number b is 10, then the numerical value c that step-by-step exclusive or obtains is replaced by 10 for 10, final 7.
By above-mentioned replacement process, final third character string 4321567 is replaced by the 4th character string
43211011010。
Step S36：4th character string is saved as into authority.
For example, the 4th character string 43211011010 is saved as into authority, it can be by defeated by the 4th character string
Go out and is realized to a null file and preservation.
When in software installation to a new hardware, then hardware ID can change.Needing to preserve installation, this is new hard
Part ID, and sequence number, licencing key and the new hardware ID of software are bound again, one is then regenerated as procedure described above
Part new authority, can just to upgrade after subsequently making user import the new authority.
The process of above-mentioned generation authority will be replaced with newly by the first character string of the generations such as the relevant information of software
The 4th character string the safety of authority is improved by the 4th text string generation authority.
Step S40：Obtain and preserve the MD5 values of authority.
The MD5 values of the authority are the MD5 values of the 4th character string.MD5, that is, Message-Digest Algorithm 5
(Message-Digest Algorithm 5) is that one of widely used hash algorithm of computer (and is translated for ensuring that information transmission is complete consistent
Digest algorithm, hash algorithm).The MD5 values can be realized by existing mainstream programming language.
Step S50：The authority, which is sent on the hardware for installing the software, to be made to load the authority on the hardware.
By above-mentioned process, the preparation for upgrading software is completed.After the completion of the preparation for upgrading software, the software
Upgrade the step that the process verified further includes specifically following：
Step S60：Whether the sequence number of inspection software is correct.
The sequence number of software is sent to network server by user's cocoa by way of being inputted on webpage.Certainly,
Network server can be made to obtain the sequence number of the software by other prior arts.For example, being stored in the network server
The sequence number #123456789abcdeABCDE of software, the then if sequence number of software input by user is also #
123456789abcdeABCDE then judges that the sequence number of software is correct, carries out step S70；Otherwise, step S130, network are carried out
Server refuses the software upgrading request of user.
Step S70：If the sequence number of software is correct, whether the hardware ID for detecting the hardware of installation software is correct.
Network server can detect the hardware ID of the hardware automatically.It is of course also possible to make net by other prior arts
Network server obtains the hardware ID.For example, be stored in the network server this with above-mentioned software sequence number binding it is hard
Part ID is 1K325476, then if the hardware ID detected is also 1K325476, determination hardware ID is correct, carries out step S80；
Otherwise, step S130 is carried out, network server refuses the software upgrading request of user.
Step S80：If the hardware ID is correct, whether the MD5 values for detecting authority are correct.
Network server can detect the MD5 values of the authority automatically.It is of course also possible to be made by other prior arts
Network server obtains the MD5 values of the authority.For example, if the MD5 values of the authority detected and the MD5 values of preservation
It is identical, then judge that MD5 values are correct, carries out step S90；Otherwise, step S130 is carried out, network server refuses the software liter of user
Grade request.
Step S90：If the MD5 values of the authority are correct, inquire authorizing whether the update time allowed expires.
For example, upgrading allow time be from activate the software from 1 year, then inquire request upgrading time
Away from whether activating from the software more than 1 year, if be not above, step S100 is carried out；Otherwise, step S130 is carried out,
Network server refuses the software upgrading request of user.The present invention inquire authorize allow update time mode not as
Limit, can also be other modes, for example, authorizing the time allowed by limiting the specific date to determine, if inquiring this
Exact date has been subjected to, then refuses upgrade request；If the exact date arrives not yet, step S100 is carried out.
Step S100：If update time is not yet due, inquire authorizing whether the upgrading number allowed is more than limitation.
For example, upgrading number can be set to 9999 times, to prevent malicious attack.If inquiring mandate permission
Upgrading number is not above 9999 times, then carries out step S110；Otherwise, step S130 is carried out, network server refuses user's
Software upgrading is asked.
Step S110：If the software upgrading number is less than limitation, whether the sequence number for inquiring the software is disabled.
If the sequence number of the software is not disabled, step S120 is carried out；Otherwise, step S130, network service are carried out
Device refuses the software upgrading request of user.
Step S120：If the sequence number of the software is not disabled, upgrade the software.
Step S130：Refusal upgrades the software.
