It tests, if ciphertext obtained is identical as the file label of the program file, illustrates that the program file is not tampered with and has
Permission is installed, verification passes through, and determines that the program file is legal installation file, client installs the program file, if being obtained
Ciphertext and program file file label it is not identical, then illustrate that the program file has been tampered or has been fitted without permission, school
Failure is tested, determines that the program file is illegal installation file, client does not install the program file.SD card or USB flash disk or light
Program file in the storage mediums such as disk is obtained by downloading from server end.Server end is for issuing and storing program text
Part.Legal installation file be sent to server end publication before, for make or handle the legal installation file its
His host side reads some or all of data in the legal installation file first, and carries out to some or all of data
Cryptographic calculation, to obtain a ciphertext, then using the ciphertext as the file label of the legal installation file, and by the legal peace
Dress file, which is sent in server end, to be issued.Particularly, the generating process of file label is completed by server end.It needs further
Illustrate, file label is located at the outside of the file data of program file, i.e., file label is not included in program file
Among appearance, thus will not Rogue program's file itself data, ensure that the integrality of program file, for example, file label can
Think the filename etc. of program file.
In a preferred embodiment, client is literary from the program is stored when needing to install a certain program file

File.The file label of legal installation file is passed through by a certain host side or server end in the reading legal installation file
File data the second file data obtained being located on designated position carry out cryptographic calculation generation.Wherein, host side, clothes
The position for the file data that device end and the client of being engaged in are read, and the type of cryptographic calculation carried out respectively are pre-stored within respectively
From system in.If read file data and client are read in same position in the generating process of file label
File data it is not identical, then it is assumed that the application program is tampered during transmission.If in the generating process of file label
In position and client the reading position of file data of reading file data is different or used Encryption Algorithm not
Together, then it is assumed that the program file is fitted without permission on the client.
For example, it is assumed that the file label of a certain application file is the filename of the application file, file name
Generating process executed by a certain host side, it is assumed that in the host side own system it is pre-set read file data position
It is the 0th byte to the 3rd byte, the cryptographic calculation carried out is md5 encryption operation, then the host side reads the application program
