Embodiment
In order to solve the problem that on software reuse module level, does not also have the corresponding protection scheme in the prior art; embodiments of the invention provide a kind of guard method of software reuse module; when certain application program need be used certain reuse module; then need to apply for the reuse module registration code; when using reuse module; then need to provide the sign of this application program, as: program process title etc.The generation of reuse module registration code needs following steps, obtain sign ID1 with application program of using the reuse module authority, according to KEY1 and ID1, utilize cryptographic algorithm to generate the first encrypted result crytoText, generate reuse module registration code licenseCode according to crytoText.Wherein key K EY1 can directly adopt reuse module private cipher key moduleKey, also can adopt and carry out after the encryption that irreversible encryption obtains moduleKeyHash as a result to reusing module private cipher key moduleKey.No matter adopting moduleKey still to adopt moduleKeyHash as KEY1, all is to obtain key K EY1 according to reuse module private cipher key moduleKey.After generating reuse module registration code licenseCode, application program 1 and licenseCode incidence relation between the two need be set up, licenseCode can be obtained when moving with convenient application program 1.Reuse module check code moduleCode and checking routine section are added in use porch at reuse module, so that by the moduleCode that carries the application program rights of using of calling it are carried out verification when it is employed program 1 and calls, moduleCode can directly adopt moduleKey, can also adopt the moduleKeyHash behind the character code, when application program 1 operation, obtain the sign ID1 ' of licenseCode, application program 1 and the moduleCode that reuse module carries.After application program 1 is called reuse module, by the moduleCode that carries the application program rights of using of calling it are carried out verification, checking procedure is, reuse module obtains key K EY1 (moduleKey or moduleKeyHash) by moduleCode, and the ID1 ' that obtains during according to key K EY1 and application program 1 operation utilizes cryptographic algorithm to generate the second encrypted result hcNumber.
The licenseCode that obtains during according to application program 1 operation obtains crytoText, and is identical with licNumber according to crytoText, determines that application program 1 has the authority of using reuse module, otherwise, there are not rights of using.
First embodiment provided by the invention is a kind of guard method of software reuse module, and xml editor is a multimedia text editor, uses as application program.One of nucleus module in the xml editor is to revise the vestige module, as a module independently, not only in xml editor, use, also frequent use in other application module, revise the vestige module in embodiments of the present invention as reuse module, below at xml editor to be application program with use reuse module authority, after modification vestige reuse module is used by an application program, the application program of using it is verified, judge whether this program is that the xml editor with rights of using describes in detail, method flow comprises as shown in Figure 1:
Step 101: adopt the private cipher key moduleA that revises vestige reuse module A, sign XMLEditor to xml editor carries out symmetric cryptography generation crytoText, with crytoText as revising vestige reuse module A registration code licenseCode, with moduleA as the check code moduleCode that revises vestige reuse module A.
Step 102: moduleCode is added on the use porch of revising vestige reuse module A, so that it carries out authorization check by moduleCode to the application program of calling it when being called.
Step 103: when application program 1 operation, obtain the moduleA that adds among the sign ID1 ' of crytoText as licenseCode, application program 1 and the modification vestige reuse module A as moduleCode.
Step 104: the moduleA that adopts modification vestige reuse module A to carry carries out symmetric cryptography to sign ID1 ' and generates the second encrypted result licNumber.
Step 105: identical according to crytoText with licNumber, determine that application program 1 has the authority of using reuse module, otherwise, there are not rights of using.
Wherein in the step 101, generating licenseCode and moduleCode can also be as shown in Figure 2, particularly, the process that generates crytoText can also be the private cipher key moduleA that revises vestige reuse module A to be carried out irreversible encryption (One-Way Encryption) obtain moduleKeyHash, the sign XMLEditor of xml editor is carried out irreversible encryption obtain appIdHash, moduleKeyHash is carried out symmetric cryptography as key to appIdHash, generate crytoText.Adopt in the present embodiment and breathe out western computing realization irreversible encryption.Being that moduleKey or moduleKeyHash effect in the present embodiment all is all to be as a key, promptly all is the key K EY1 that obtains according to reuse module private cipher key moduleKey.The effect of key K EY1 is exactly and sign XMLEditor can generate crytoText together.To XMLEditor and moduleA encryption is unidirectional, guarantees that crytoText can not be cracked, and has strengthened the security of revising vestige reuse module A.Further, can also obtain licenseCode and moduleCode in the following way, use random number as key crytoText to be carried out symmetric cryptography, the result of encryption uses cryptoRandKey to represent.Use random number that crytoText is encrypted, it is all different to guarantee to revise the each registration code that generates of vestige reuse module A.The random number that the cryptoRandKey and the previous step of generation are used is spliced to form licCode, uses character-coded mode to generate character visible licCode and moduleKeyHash, forms licenseCode and moduleCode.
Owing to establish the incidence relation of application program 1 and licenseCode before, as licenseCode being added in the relevant configuration file of application program 1, or licenseCode is added in the string resource of the relevant resource file of application program 1, or the porch of licenseCode being write application program 1.Therefore obtaining the concrete enforcement of licenseCode can be, during application program 1 operation, the module such as the softdog that carry out follow-up Authority Verification can obtain licenseCode by reading the configuration file that carries licenseCode.Perhaps, softdog reads the resource file that is added with licenseCode in the string resource, obtains licenseCode.Perhaps, with the porch that licenseCode writes application program 1, during application program 1 operation, softdog directly obtains licenseCode by application program 1.Softdog is registered in the licenseCode that obtains and offers the subsequent step use in the internal memory.
Carry out the licenseCode that obtains after the encryption if use random number, before step 105, also need to obtain crytoText according to licenseCode, as shown in Figure 4, be specially licenseCode is decoded, be converted into licCode by licenseCode, isolate random code and cryptoRandKey from licCode, random code is decrypted computing as key to cryptoRandKey, generates crytoText.CrytoText can be inserted in the registration code sequence of application program during concrete enforcement, use when wait and licNumber compare.
For step 105, determine that crytoText is identical with licNumber, can be by crytoText and licNumber being carried out determine relatively that directly both are identical, also can be, before step 105, use random number (identical) licNumber to be carried out symmetric cryptography as key with the random number of encrypting crytoText, with the result and the random number splicing of encrypting, obtain a splicing result, to splice the result and use character-coded mode to generate character visible, form last registration comparison code, will register comparison code and licenseCode compares, identical according to comparative result, determine that crytoText is identical with licNumber.
