Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Encryption lock is a kind of security product that is inserted in the software and hardware combining on the computer interface, generally all have tens or the nonvolatile storage space of hundreds of byte can be for read-write.The software developer can pass through application programming interface (Application Programming Interface, API) and encryption lock carry out exchanges data, so the software developer can be provided with the many places software locks in software, utilize encryption lock to open these locks as key, simple encryption lock is when a certain step is arrived in program run, just judge whether some data meets some condition in the encryption lock, and how determination procedure is carried out then; Complicated encryption lock is some power function in the program to be placed in the encryption lock move, and decides program how to carry out by the contrast rreturn value.
The embodiment of the invention is made corresponding encryption lock according to the protection mode of securing software, when detecting this encryption lock, according to the check results to this encryption lock protection mode is switched to corresponding pattern.
Fig. 1 shows the realization flow of the protection mode changing method that the embodiment of the invention provides, and details are as follows:
In step S101, make corresponding encryption lock according to protection mode;
Encryption lock can be made in the process of exploitation securing software, can also make in the process that securing software is installed.For example: be saved in some data in the securing software program in the encryption lock or some power function is placed in the encryption lock and move.
The interface of encryption lock and computing machine can be parallel port or USB (universal serial bus) (Universal SerialBus, USB), certainly can also so both strengthen the disguise of encryption lock for cassette directly is inserted in the mainboard expansion slot of computing machine, also improve the access speed of encryption lock.
In the computing machine use, when securing software has detected encryption lock and connects on computers by API or self-defining interface function, continue to carry out following step:
In step S102, encryption lock is carried out verification, when verification by protection mode being switched to corresponding pattern.
When securing software had only major and minor two kinds of protection modes, the protection mode of acquiescence was a secondary mode, and the rreturn value of some data or some power function is correct in judging encryption lock, then switched current protection mode to holotype; Otherwise continue to keep the secondary mode of securing software.
In another embodiment of the present invention, can when computing machine connects different encryption locks, then enter the corresponding protection mode of securing software, thereby realize the switching between a plurality of protection modes of securing software by making a plurality of unduplicated encryption locks.
For better explanation the present invention, be illustrated below by an example:
Suppose the exploitation securing software process in, in the program just like next the section:
......
A＝Fx(3)；
......
It is the value that program will obtain variables A according to constant 3.Can write following cryptographic algorithm this moment built-in in the encryption lock of CPU:
DogConvert(1)＝12345；
Just can be rewritten into following form to original program A=Fx (3) this moment:
A＝Fx(DogConvert(1)-12342)；
Just constant 3 can not occur in the original program like this, and have only the software developer to know that just the actual constant that calls is 3.After installing this securing software, on computing machine, do not connect this encryption lock, then function DogConvert () just can not return correct result, and the result of formula A=Fx (DogConvert (1)-12342) certainly can be incorrect yet, so the protection mode of securing software remains secondary mode; Connected this encryption lock on computing machine, judged in the program that the operation result of A is correct, then the protection mode with securing software switches to holotype.In addition, can also also store 12342 in the above-mentioned formula in the internal storage of encryption lock, read function DogRead () by definition in encryption lock and read this data, make the value of A depend on function DogConvert () and DogRead () in the encryption lock fully, thereby make the deciphering difficulty more that becomes.
