Step S201, generates the unique identification for the treatment of facility to be certified by the step of described generation encrypt file;
Step S202, reads the unique identification in encrypt file and obtains authentication result with the unique identification comparison of described treatment facility to be certified.
Encryption and authentication method provided by the invention, by obtaining CPU information and the mac address of nic information of hardware place to be encrypted treatment facility; Encrypt the identification information that described CPU information and described mac address of nic information are spliced into, generate the unique identification of hardware to be encrypted; Thus can generate there is uniquely identified encrypt file.In addition, this method is by obtaining the unique identification for the treatment of facility to be certified by the step generating encrypt file; Read the unique identification in encrypt file and obtain authentication result with the unique identification comparison of described treatment facility to be certified.Thus an encrypt file corresponding treatment facility uniquely can be made, control the rights of using of a treatment facility to software uniquely for utilizing encrypt file and lay the foundation.
In the specific implementation, generate the uniquely identified method for the treatment of facility to be certified, can comprise the following steps:
Obtain CPU information and the mac address of nic information for the treatment of facility to be certified;
Splice the identification information that the CPU information for the treatment of facility to be certified and mac address of nic information generate treatment facility to be certified;
The identification information encryption treating authentication processing device generates the unique identification for the treatment of facility to be certified.
In the specific implementation, hardware place treatment facility to be encrypted and treatment facility to be certified can be mobile phone, PC (PersonalComputer) computer, panel computer, vehicle-mounted computer, intelligent watch or other smart machines.In the specific implementation, hardware place treatment facility to be encrypted and equipment to be certified also can be the virtual units such as virtual machine.

The benefit of design like this is, can ensure obtain hardware to be encrypted unique identification UID uniqueness prerequisite under, avoid the unique identification UID by cracking hardware to be encrypted expose hardware place to be encrypted treatment facility CPU information and mac address of nic.
In the specific implementation, alternate manner also can be adopted to encrypt described identification information character string.Such as can utilize data encryption standard algorithm (DataEncryptionStandard) DES or utilize public key cryptography algorithm RSA to be encrypted described identification information character string, using the test value that obtains after encryption as the unique identification UID of described equipment.
For example, the CF card a (i.e. hardware to be encrypted, it can also be entity hard disk, also can be virtual hard disk etc.) for the treatment of facility A (this equipment can make PC or virtual machine etc.) has suffered generation encrypt file; Known by above-mentioned steps, obtain the CPU information on treatment facility A and mac address of nic information, and the CPU information on obtained treatment facility A and mac address of nic information are spliced, so just obtain identification information, again the unique identification that (can adopt the MD5 value calculating described identification information) obtains CF card a is encrypted to described identification information, and utilizes this unique identification to generate encrypt file (i.e. license file).
If now someone obtains by carrying out the means such as mirror image burning card to CF card a the CF card b comprising its encrypt file, and CF card b is utilized on other treatment facilities, as utilized on treatment facility B (i.e. treatment facility to be certified), the unique identification now generated on treatment facility B utilizes the CPU information on treatment facility B and mac address of nic information to splice and obtains after encrypting, because the CPU information on treatment facility A and mac address of nic information exist different from the CPU information on treatment facility B and mac address of nic information certainly, therefore the unique identification produced on treatment facility B is certainly different with the unique identification in encrypt file, when comparing result is different, corresponding function or the authority for the treatment of facility B can be limited, thus the economic interests of protection manufacturer.This method, by binding by force with hardware, uniquely can confirm a hardware device, have more accuracy; And can prevent copy from occurring, avoid same license also can come into force on multiple distinct device, thus the economic loss caused.
