Fuzzy self-adaption variable carries out Fuzzy processing；Secondly the fuzzy self-adaption strategy based on fuzzy rule is edited, then to editor
Good fuzzy self-adaption strategy carries out syntax error inspection；Emulation testing finally is carried out to fuzzy self-adaption strategy；
Step 2, fuzzy self-adaption strategy is stored：Fuzzy operation is matched somebody with somebody first with fuzzy logic basic operation module
Put, store path, mould described in storage configuration information and step 1 then are set using fuzzy self-adaption logic persistent storage module
Self-adaptive fuzzy input, output variable, fuzzy self-adaption rule, realize the recycling of fuzzy self-adaption logic and share；
Step 3, generation fuzzy self-adaption Aspect：Base is automatically generated using fuzzy self-adaption Aspect facility automatically-generating modules
In the fuzzy self-adaption Aspect files of executable language codes；
Step 4, braiding fuzzy self-adaption Aspect：Instrument is woven by general Aspect, the Aspect texts that step 3 is generated
Part is woven into target software, so as to be internally formed the adaptive ring of software obfuscation in target software.
5. the adaptive development approach of software obfuscation according to claim 4, it is characterised in that：Using soft described in step 1
Part fuzzy self-adaption visual edit and emulation testing module editor and emulation testing fuzzy self-adaption strategy, be specially：
(1) adaptive dependent variable is determined：Determine to obscure certainly according to fuzzy self-adaption demand and the fuzzy self-adaption target of target software
Adaptation input, output variable, are obscured certainly needed for software obfuscation adaptive visualization editor and emulation testing module add one by one
Adapt to input, output variable；
(2) the adaptive dependent variable of obfuscation：Step (1) is added with emulation testing module in software obfuscation adaptive visualization editor
Plus fuzzy self-adaption input, output variable carry out fuzzy partition, generate multiple fuzzy language values, and be each fuzzy language
Value defines membership function；
(3) fuzzy self-adaption strategy is edited：Mould is based in software obfuscation adaptive visualization editor and emulation testing module editor
The fuzzy self-adaption strategy of rule is pasted, syntax error inspection then is carried out to the fuzzy self-adaption strategy editted；
(4) fuzzy self-adaption strategy is tested：In software obfuscation adaptive visualization editor and emulation testing module to editting
Fuzzy self-adaption strategy is patterned emulation and tested, to find the logic error implied in fuzzy self-adaption reasoning, test
Process needs fuzzy logic basic operation module, the support of fuzzy logic enforcement engine module.
