【摘要】 库函数研究是反编译中最关键和最有应用价值的问题之一。与系统库函数最明显的不同是,为了构造识别模板,需要通过反编译获取用户库函数的原型信息。本文介绍将反编译技术应用于用户库的中间代码到接口和源代码恢复的过程。建立从用户库中提取函数的名称、参数个数和类型信息的模型。提出使用已有用户库代码构成识别模板的方法。这些方法和技术已通过某实际用户库进行了验证。更多还原

【Abstract】 Research of library function is one of the most important and valuable problems in decompilation.The introduction of prototype information of user library function,which is obviously different from system library function,must be obtained through decompilation to build recognition pattern.The process model to extract name of a function and number of parameters and information of type from library,which are built using the current reverse theory and technology,is introduced in this paper.We also present the possibility of obtaining recognition pattern from user library.All above are validated by the user library of a practical software in the final.更多还原
