Abstract
The invention discloses a method for protecting the copyright of an embedded system by a software protection device. The method comprises: utilizing the IO of a software protection device to control a plurality of functions of the embedded system, so as to make the software protection device to be a component of one hardware of the embedded system. Therefore, because the pirate can not attain the software protection device that is fully identical with the software protection device owned by the developer of the embedded system ('fully identical' denotes that the hardware of and the codes in the software protection devices are the same), the embedded system can not be completely pirated.
Description
Technical field
The present invention relates to the software copyright protection field, particularly a kind of software protecting equipment that utilizes is realized the embedded system copy-right protection method.
Background technology
Along with economy, development of science and technology, embedded system more and more widely be applied to every field, as Medical Devices, navigator, smart mobile phone or the like.Owing to be subjected to the restriction of embedded system hardware resource, embedded system often can't be implemented complicated encipherment scheme.Cause the pirate industrial chain of embedded system to be grown like this and walked crosswise, brought very big economic loss for the developer of legal embedded system.
Summary of the invention
In view of this, the invention provides a kind of method of using the software protecting equipment realization to the embedded system copyright protection.Technological core of the present invention is to use some functions of the IO control embedded system of software protecting equipment, makes software protecting equipment become an ingredient of a hardware of embedded system.Because the bootlegger can't obtain and the on all four software protecting equipment of embedded system development merchant (code is all the same in the hardware and software protective device that is meant software protecting equipment in full accord), thereby can't be fully to embedded system piracy.
According to an aspect of the present invention, provide a kind of method of embedded system copyright protection, wherein adopt software protecting equipment that embedded system is carried out copyright protection, it is characterized in that the method comprising the steps of:
A, to software protecting equipment programming, make software protecting equipment realize the required function of embedded system;
B, the software protecting equipment that will programme are connected to the hardware circuit of embedded system;
C, embedded system trigger software protecting equipment;
D, software protecting equipment carry out internal code and control hardware capability module in the embedded system.
According to an aspect of the present invention, its feature also is, in steps A, according to the design requirement of embedded system, software protecting equipment is programmed.
According to an aspect of the present invention, its feature also is, in step B, according to the design requirement of embedded system, software protecting equipment is connected on the hardware circuit of embedded system, makes software protecting equipment become the ingredient of embedded system.
According to an aspect of the present invention, its feature also is, also comprises in step C the data of software protection needs are passed to software protecting equipment.
According to an aspect of the present invention; its feature also is; the internal code of the software protecting equipment that software protecting equipment execution embedded system is write; the internal code of software protecting equipment is finished the function that embedded system needs by the hardware capability module of the IO control embedded system of software protecting equipment.
