【摘要】 二进制代码的逆向工程是一个底层的技术,被应用于计算机安全、系统验证、加密解密等相关领域。在逆向工程中,C++的反编译技术是一个难点,尤其是其类型信息的恢复。该文提出了一种利用异常处理机制的类型恢复方法,该方法可以用来分析出每个函数的所有局部类变量,还能分析出这个类的构造函数和析构函数的地址。该方法在特定的环境下可以准确高效地解决C++反编译中的一个难点。更多还原

【Abstract】 Reverse engineering of binary programs is a fundamental task for specialists in the fields of computer security,system verification,cryptography,and other related fields.The decompilation of C++is a very difficult problem in reverse engineering,especially the type recovering.This paper presents a technique to recover data type based on C++exception handling.It can find out all the local objects in a function and analyze the addresses of the object’s constructor and destructor.In specific environment,this approach is a good solution of recovering data type information in C++decompilation.更多还原
