Description
Technical field
The invention relates to a kind of Software Protection Technique, particularly utilize version detection and install many places affirmation password software is carried out the method and system of encipherment protection at the program key point about a kind of.
Background technology
Software is used for commander and the operation of control information device hardware, till the extremely formal commercialization of software development initial stage, the software developer must drop into a large amount of exploitation manpower and cost, can just the software listing can be sold after stable operation on the information equipment until the software of being developed.At this moment, input huge cost when software supplier develops for regaining as early as possible, make the software price high, can't in most information equipments, popularize, moreover, all be stored in because of software in the storing medias such as CD or floppy disk, be easy to circulation and propagate, so increased by the probability of duplicating by various data processing techniques.Therefore, software cryptography becomes a kind of necessary means of protection software, and the software major part of selling is taked certain encryption method at present, and its purpose is to protect software developer's interests and prevents that software from being duplicated arbitrarily, piracy.The used software enciphering method of software developer is broadly divided into two classes at present: hardware encipher and software cryptography.
Hardware encipher is that combination of hardware with software and information equipment is to carry out encipherment protection to software; the software that adopts hardware encipher is when carrying out; need and the relevant hardware swap date; if there is not relevant hardware to cooperate; software after the encryption can't move; though this method has the Cipher Strength height; advantages such as encryption performance is good; but need specific hardware supported ability entire run; this inconvenience is one of its shortcoming; therefore, this method is used for software developer that Cipher Strength, compatibility, stability are had higher requirements more.
Software cryptography is with the pure software method software to be encrypted, and its cipher mode mainly contains pin mode, software self-checking mode, license management mode and key floppy disc mode etc.
Pin mode is meant the important local inquiry password of information equipment in software execute process, and the user must be according to the input password of password epiphase correspondence, and program could continue to carry out.The advantage of this mode be implement simple, hardly must input cost, but exist defectives such as destroying normal man-machine conversation, password and pass point relative fixed, therefore be mainly used in the lower software of price, as Games Software etc.
When software self-checking mode refers to that the software developer packs software into user used hard disk, the information such as track location that the parity check sum software of installation procedure automatic logger computer hardware of meeting in installation process is installed, perhaps at special track, CMOS (the Complementary Metal-Oxide Semiconductor of hard disk, complementary metal oxide semiconductor (CMOS), be a kind of storer on the computer main frame panel) in do a mark, and rewrite installation procedure automatically, when after this software was carried out, the information or the mark of record carried out verification when promptly these being installed.If software is copied to by the user on other the information equipment, because of running environment changes, software can't normally move.Make and to make the user in this way when legal use software; the existence of imperceptible encryption; and information equipment is relatively also more stable; so many software developers have adopted this mode to protect the software of being developed; but also there is certain defective in this cipher mode; for example; when user increase and decrease or when changing computer hardware, compressed drive or situation such as CMOS power down occurring; the capital causes software normally to carry out; need reinstall software and just can address the above problem, for just inconvenience more of user.
The license management mode is meant that software is in installation process, information equipment to legal user detects, special finger print information so as to the acquired information device hardware, and the computation process (the installation sequence number of finger print information and this software self is carried out computing) by algorithm, obtain representing a string data of this software, and require the user that this data is registered by modes such as Internet, Email, telefacsimile, mails, if legal user can obtain a registration code (or confirmation code) there the software developer.After legal user wants installed software to this registration code input; this software can normally move; this cipher mode is actually software and information specific device hardware is carried out " binding "; making the user software can't be copied on the out of Memory equipment uses; because of the hardware fingerprint of every station information equipment all inequality; so; this mode is to the implementation of software and have no effect; its shortcoming is; software developer's services amount will be increased; it is reported that using special register machine to produce registration code will become following main flow, promptly adopted this cipher mode to carry out software protection as the Office2000 of Microsoft (Microsoft).
The key floppy disc mode is that the special track at floppy disk writes a customizing messages, software is this customizing messages of palpus verification in operational process, this floppy disk resembles a key, thereby be called key floppy disc by people custom, adopt the software cryptography instrument of this cipher mode a lot, wherein, advanced software cryptography instrument also provides interface function, the software developer only needs disposable purchase one cover Encryption Tool, get final product many key floppy discs of self manufacture, come the verification key floppy disc whether to exist and in software, read magnetic track special on the key floppy disc.This software cryptography mode is easy, cost is low, encryption is reliable; but also there is defective simultaneously; must in floppy disk, insert floppy disk during as user's executive software; cause the user in floppy disk, to carry out the inconvenience of data access; and floppy disk is a kind of consumables; through regular meeting because of lose, scratch, magnetization and reason such as cold and hot cause to damage data can't be read; and software that floppy disk stores and data still are available for users to backup; key floppy disc then can not, so the user often has the awkward situation that causes software normally to use because of reasons such as key floppy disc damages.
