ARM二进制敏感性数据检测方法研究

Research on detection method for ARM sensitive binary data

相对于PC成熟的安全防护而言,嵌入式安全依旧处于薄弱状态。以ARM为研究对象,结合ARM指令体系的结构和特点,为实现对二进制可执行文件BIN中是否存在对硬件模块的操控,展开敏感性信息的匹配,预警恶意操作,并提出半定型建模匹配方式,加快了代码定位分析效率。

Compared with PC mature security protection,the embedded security remains in weaker state. To achieve whether the control to hardware module exists in BIN of binary executable file,ARM is taken as research object,and sensitive informa?tion matching is conducted,and malicious actions are forewarned in combination with the structure and characteristics of ARM instruction system. The matching way of semidefinite form modeling is presented,which speeds up the code positioning analysis efficiency.
