摘要
虚拟设计分析方法是一套对加密软件分析的实用技术。根据封闭软件的阶段特征制定虚拟阶段目标,进行分析和验证获得实际目标。早期生产的集散控制系统一般是封闭的,很难提取其实时数据。采用虚拟设计分析方法,可有效地分析出隐藏于总控机内存或外存中的数据。用TSR技术提取有用数据,经网关动态传送到信息网络上,实现双网实时数据传输。
The analysis method of virtual design is a set of utility techniques for encryption software analysis. The virtual phase goal is assumed according to the phase features of lockout software. The real goal is achieved through analysis and verification. The DCS made earlier is usually lockout. It is difficult to get the real time data from lockout DCS. The data hidden in memory or disk of the control computer can be obtained through analysis of the analysis method of virtual design. The useful data stolen by TSR technology is sent really to information network by gateway.
