Detailed description of the invention
The present invention is described in detail with embodiment below in conjunction with the accompanying drawings.
Refering to Fig. 1, Fig. 1 is the flow chart of method one embodiment of application file of the present invention checking, comprising:
Step S101: mobile device obtains the first check code and second check code of application file, wherein, the first school
Testing code is to obtain according to the first authority information that application file itself carries, and the second check code is according to application journey
The second authority information that the legal copy of preface part is carried obtains, the second mandate that the legal copy of described application file is carried
The legal copy corresponding authority information of the i.e. described application file of fileinfo.Mobile device obtains application file
First check code and the second check code also can include two independent steps, i.e. include: mobile device obtains application program literary composition
The step of the first check code of part, mobile device obtain the step of the second check code of application file.
Application file, after distribution or pirate, or user is during using, and is tampered, these
Consumer's Experience is all caused to reduce.In prior art, it is common that by way of input active coding or registration code, ensure to apply journey
Preface part is legal copy rather than pirate.But, on the one hand, for mobile device, input long code very inconvenient, the opposing party
Face, active coding or registration code also can be tampered.
In embodiments of the present invention, after application file corresponding legal generation, i.e. produce corresponding second and award
Power fileinfo, the second authority information refers to the authority information one to one of the legal copy with application file, example
As: unique signature of setting, equipment Serial Number, application file bag name, unique temporal information etc. of determination.This is second years old
Authority information is attached in the corresponding legal copy of application file.If the second authority information is tampered, then show
This application file has been tampered with.Second authority information is typically application developers or the clothes of application developers mandate
Business business determines.
First authority information refers to corresponding to the second authority information and the one_to_one corresponding of application file own
Authority information.For example, if the second authority information is the signature unique setting, then the first authority information
Being also corresponding signature, only this signature is possible to consistent with the signature unique setting, it is possible to make at application file
Used time is tampered and inconsistent with the signature unique setting, or application file is originally pirate, and signature is naturally also
Inconsistent with the signature unique setting.
Obtain the first verification according to the first authority information that application file itself carries by certain method
Code, obtains the second check code according to the second authority information that the legal copy of application file is carried by certain method.
Wherein, it is thus achieved that the method for the first check code can be identical with the method obtaining the second check code, it is also possible to differs, differs
When, it is thus necessary to determine that the corresponding relation between the first check code and the second check code, to determine the first check code and the second verification
Whether code is consistent.
Step S102: mobile device, when the first check code and the second check code are consistent, determines that application file passes through
Checking.
Relatively the first check code and the second check code, if the first check code and the second check code are consistent, determines this application
Program file, by checking, that is to say that this application file is consistent with the legal copy of application file, this application program
File is not tampered with, and mandate is effective.Certainly, the legal copy of this application file is after follow-up use process, still has
May be tampered, if be tampered during follow-up use, then the first check code and the second check code are just inconsistent.
If the first check code and the second check code are inconsistent, prompting user application file has been tampered with, and continues
Use risky, or application file is piracy, and guide user to use the official of application file legal.
Embodiment of the present invention mobile device obtains the first check code and the second check code, first school of application file
Testing code is to obtain according to the first authority information that described application file itself carries, and described second check code is root
Obtain according to the second authority information that the legal copy of described application file is carried；Described mobile device is in described first school
Test code consistent with described second check code when, determine described application file by checking.Due to application file just
The second authority information that version is carried, application file itself carries the first authority information, works as application file
When being not tampered with, the first authority information is consistent with the second authority information, the first check code and the second verification
Code is also consistent, and after application file is tampered, the first authority information and the second authority information are to differ
Causing, the first check code and the second check code are also inconsistent, in this way, can determine application file in mobile terminal
Security, and longer code need not be inputted.
Wherein, the first authority information is the first signing messages, and the second authority information is the second signing messages.
Now, in step S101, mobile device obtains the step of the second check code of application file, can pass through two
The mode of kind realizes, one is in the case of network-in-dialing, and mobile device can obtain the second verification by network from server
Code, another kind of situation is that developer is built in the second check code in the legal copy of application file, when user obtains application journey
The legal copy of preface part, after the legal copy of the mobile device set up applications of oneself, in this application program (application journey i.e. installed
The legal copy of preface part) in follow-up checking, network can be independent of, mobile device directly obtains and is built in application file
The second check code.
See Fig. 2, no matter be above-mentioned any mode, before step S101, be first required to generate the second check code,
Combine detailed process can be such that
Step S103: the second signing messages that server has been arranged by the legal copy to application file for the hashing algorithm enters
Row calculates, and obtains the second check code.This step can complete at the service provider of application developers or application developers mandate.Enter
One step ground, server is built in the second check code in the legal copy of application file, and this is built-in with the application of the second check code
The legal copy of program file reaches user side.
If there is network when application file starts, mobile device passes through Network Capture the second check code, then enter
Step S1011, if do not have network when application file starts, mobile device obtains the second check code in this locality, then enter
Enter step S1012.
Step S1011: by network attached server, and then obtain the second verification of application file from server
Code.
Step S1012: obtain the second check code being built in application file.
Although it will be apparent that the second check code is to be built in the legal copy of application file, but still there is security
Risk.It is possible to further process is encrypted and decrypted to the second check code by way of public affairs, private key, to enter one
Step increases the security of application file.
Wherein, in step S101, the step of the first check code that mobile device obtains application file may is that step
S1013, the first signing messages being carried application file itself by hashing algorithm is calculated, and obtains the first verification
Code.The method of the method and acquisition the second check code that i.e. obtain the first check code is just as, and is all hashing algorithm.
Hashing algorithm refers to produce the algorithm of the hashed value of some data slots (such as message or session entry).Good hash
Algorithm has the characteristic changing hashed value result according to the variation in input data；Therefore, hash is such as disappearing for detection
Any change in the large-scale information objects such as breath is very useful.
Hash function in software development or hashing algorithm, also known as hash function (Hash Function), be a kind of from appointing
What a kind of data creates the method for little numeral " fingerprint ".Hash function becomes summary message or data compression so that data
Amount diminishes, and is fixed up the form of data.Data are upset mixing by this function, re-create a finger being called hashed value
Line.Hashed value is commonly used to represent the character string of a short random letters and numeral composition.Good hash function is at input domain
In hash collision seldom occurs.At hash table and Data processing, do not suppress conflict to carry out distinguishes data, data-base recording can be made
It is more difficult to find.All of hash function is all just like next fundamental characteristics: if two hashed values be differ (according to same
Function), then being originally inputted of the two hashed value is also differ.Hashing algorithm include but is not limited to SHA1, MD5,
SHA256 etc..Certainly, it is thus achieved that the method for the method of the first check code and acquisition the second check code is except being above-mentioned hashing algorithm
Outward, can also is that other methods, do not limit at this.
In actual applications, above-mentioned signing messages proof procedure can realize checking with Java code, it is also possible to uses C language
Code realizes checking, specific as follows:
1st, the shallow verification of Java layer (Validation Code is at Java layer)；
For example, in Java code, checking signature specifically may is that
Owing to Java code includes a lot of source code information, such as variable name, method name, and come to visit by these titles
Asking variable and method, these symbols are with many semantic informations, it is easy to decompiled into Java source code.This in order to prevent
Phenomenon, can use the mode of Code obfuscation, improve the difficulty of decompiling to Java code.
2nd, in primary development kit (Native Development Kit, write a Chinese character in simplified form NDK) C code, verification (verifies generation deeply
Code is in the C code of NDK)；
C language realize with the realization of Java in flow process similar, only code difference, no longer illustrate in detail.Due to C language
The program write typically is difficult to decompiling, it is impossible to obtain source code, and compiling has been converted into machine language after completing, is not completely may be used
Inverse process, the engineering that therefore decompiling C language generates, the engineering challenges than decompiling Java is a lot.
In the embodiment of the present invention, the process of checking application file can verify on backstage, does not affect application program literary composition
The toggle speed of part.
Wherein, the second authority information include with the legal copy of application file corresponding application file bag name,
The authorization message of at least one classification in equipment Serial Number, unit type, the term of validity of setting, functional specification information；First
Authority information includes and application file corresponding application file bag name, equipment Serial Number, unit type, setting
The term of validity, the authorization message of at least one classification in functional specification information.Wherein, functional specification information i.e. limits application journey
Preface part can use the information of function, and described first authority information is also mutually corresponding with the second authority information, for example,
Second authority information includes the legal copy of application file corresponding application file bag name, then the first authority
Information also includes and application file corresponding application file bag name；And for example, the second authority information includes application
The legal copy corresponding application file bag name of program file and equipment Serial Number, then the first authority information also include with
Application file corresponding application file bag name and equipment Serial Number.Certainly, the second authority information is not limited to
Foregoing, does not limit at this.
Wherein, described with application file legal copy corresponding application file bag name, equipment Serial Number, equipment type
Number etc. classification authorization message in, may each comprise multiple object, the even first authority information include and application program literary composition
It during part corresponding application file bag name, is somebody's turn to do the corresponding application file Bao Mingzhong with the legal copy of application file permissible
Including multiple application file bag names, this reader of such as e, this store of e etc.；If the first authority information includes equipment sequence
During row, then this equipment Serial Number can include multiple equipment Serial Number；If the first authority information includes unit type, if
Standby model also can include multiple unit type, such as this T8 of E people E, E people this T9 of E etc..In like manner, the second authority information is also
Can be arranged such that, so can realize an authority bag to multiple application files, or multiple equipment Serial Number, or
Multiple unit types realize authorizing, to improve application file authority checking efficiency.
Now, seeing Fig. 3, in step S101, mobile device obtains the first check code and second school of application file
Before testing the step of code, also include:
Step S201: server generates the second authority letter of the corresponding text formatting of legal copy with application file
Breath.
The legal copy of application file is before dispatching from the factory, according to application file bag name, equipment Serial Number, unit type
At least one in (or device customizing model), the term of validity setting etc. generates the second authority information of text formatting,
Text form can be .txt form, JSON form or XML format etc., wherein, and the authority letter of preferably JSON form
Breath, the authority information of JSON form is in the comparison of subsequent authorization item, and comparison efficiency is high.
For example, the second authority information authorization.json (referring to be exemplified below).
Step S202: the second authority information is calculated by server by hashing algorithm, authorized check code,
Check code is authorized to be the second check code.
For example, according to hashing algorithm, such as SHA1, MD5 or SHA256 etc., to the second authority information evaluation, dissipated
Train value is mandate check code, such as SHA1 value, MD5 value, or SHA256 value etc..
If the mandate check code that the second authority information is asked changes, then the corresponding second i.e. quilt of authority information
By authorizing check code, modification, therefore may determine that whether the second authority information is modified, the second authority information quilt
(check code is authorized to change) after modification, i.e. it is believed that the second authority information lost efficacy, the legal copy of this application file
It has been modified.
Equally, in step S101, mobile device obtains the step of the first check code of application file, may is that shifting
Dynamic equipment obtains authority bag, and this authority bag includes the information of the second check code；By hashing algorithm to application journey
The first authority information that preface part itself carries calculates, and obtains the first check code.
Described authority bag includes the information of described second check code, can be the second check code, or, Ke Yishi
Described authority signature (authority signature encryption the second check code obtains).
It should be understood that when the second authority information is the literary composition of the corresponding application program with the legal copy of application file
Part bag name, equipment Serial Number, unit type, setting one of the term of validity when, the first authority information is also corresponding
One；When the second authority information is corresponding application file bag name, equipment sequence with the legal copy of application file
Number, unit type, setting the term of validity in two when, the first authority information is also corresponding two, now all right
Set the checking of further application file, for example: legal corresponding for application file of the second authority information
Application file bag name, equipment Serial Number, the first authority information is corresponding application program with application file
File bag name, equipment Serial Number.In the second authority information (authorization.json as described below), Ke Yijin
One step explanation grant item also includes the term of validity setting, and i.e. when the second check code and the first check code are consistent, after checking, enters
Row further checking, whether the term of validity of confirmation application file is in the term of validity setting, if not having of setting
In the effect phase, then this checking is not passed through.
And for example: the second authority information is equipment Serial Number, the first authority information is equipment Serial Number, second
In authority information, can further illustrate grant item also include application file bag name, unit type, setting effective
Phase, i.e. when the second check code and the first check code are consistent, after checking, further verified, confirmed application journey respectively
Whether the application file bag name of preface part, unit type, the term of validity be consistent with set in the second authority information, only
Wherein to have one inconsistent, then this checking is not passed through.
Certainly, in above-mentioned example, it is also possible to when verifying for the first time, the second authority information includes whole mandates
, only when the second check code including whole grant item is consistent with the first check code including whole grant item, just calculate logical
Cross checking.The concrete checking how realizing application file, can according to reality apply it needs to be determined that, do not limit at this
Fixed.
Mobile device, when obtaining the second check code, still can use networking to obtain from server and obtain two in this locality
The mode of kind, no longer goes to live in the household of one's in-laws on getting married at this and chats.It is mainly described when obtaining in this locality below, in order to be further ensured that the peace of application file
The measure that full property is taked.
See Fig. 4, after step S202, can also include:
Step S203: server generates PKI and private key by rivest, shamir, adelman.
Rivest, shamir, adelman, such as RSA, Elgamal, knapsack algorithm, Rabin, D-H, ECC etc..Application developers retains
Private key, private key is used for encryption authorization check code, and to generate authority signature (following steps S204), PKI is used for deciphering mandate
File signature, authorized check code.It is of course also possible to use symmetric encipherment algorithm, do not limit at this.
Step S204: server uses private key to authorizing check code encryption, generates authority signature, for example:
Authorization.json.sign authority is signed.
Wherein, the second authority information, authority signature, PKI are required to be built in application file.Example
As by the second authority information authorization.json, authority signature authorization.json.sign beats
Bag, generates zip compressed package (authority bag), such as authority bag license.zip；By authority bag license.zip
Issue the user obtaining mandate after application authorizes, or directly before equipment or terminal dispatch from the factory, utilize authority bag
Pre-installed applications is authorized by license.zip.
PKI can be built in the legal copy of application file by server, it is also possible to is saved in server local.When
Mobile device is not networked when verifying, server can be built in PKI in the legal copy of application file, sets when mobile
When standby networking is verified, PKI can be saved in server local by server.Networking or the flow process verified of not networking,
May refer to foregoing, no longer go to live in the household of one's in-laws on getting married at this and chat.
Now, seeing Fig. 5, in step S101, mobile device obtains the step of the second check code of application file, bag
Include:
Step S301: mobile device obtains the PKI being built in application file.
Step S302: authority signature is decrypted by mobile device by PKI, it is thus achieved that authority checking code, mandate is tested
Card code is the second check code.
It should be noted that the execution of above-mentioned steps S101 and step S102 can be when application file starts
Wait and perform, it is also possible to be to perform in application file running.
Authority bag also includes the second authority information, the second authority information, the first authority information
In all corresponding grant item of authorization message of each classification；Mobile device when the first check code and the second check code are consistent,
Determine that application file passes through checking, comprising:
When the first check code and the second check code are consistent, mobile device is by each grant item in the second authority information
Compare with corresponding grant item in the first authority information respectively, if in the second authority information each grant item with
In first authority information, corresponding grant item is all mated, then determine application file by checking.
Grant item can be application file bag name, equipment Serial Number, unit type, the term of validity of setting, function limit
Determine the authorization message of at least one classification in information.Corresponding grant item coupling refers to the authorized content phase of concrete grant item
Coupling.If in the second authority information, each grant item is mated with corresponding grant item in the first authority information, i.e.
Represent in the grant item that the second authority information is identical with the first authority information that there is identical object content, this mesh
Mark content is the application file characteristic of correspondence information of current authentication, such as application file bag name, application program literary composition
The unit type (unit type i.e. described above) of part place equipment, or the equipment sequence of application file place equipment
Row number etc..
For example, the first authority information and the second authority information all include application file bag grant item,
