目的研究安全分析中数据与信息合成的方法．方法分析了安全分析中数据的种类与来源，讨论了运用于安全分析中信息与数据合成的三种基本理论：概率理论、证据理论和可能性理论的数学基础及其信息合成的规则．结果明确了三类方法的特点和相互关系，在实际的安全分析中以上信息合成方法还存在较大的局限性．结论概率理论、证据理论和可能性理论在安全分析的信息合成中的应用有待进一步深入研究，新的信息合成技术有待开发．
Objective To study the method of data and information synthesis in security analysis. Methods The types and sources of data in security analysis are analyzed. Three basic theories of information and data synthesis in security analysis are discussed: the mathematical basis of probability theory, evidence theory and probability theory, and the rules of information synthesis. The results clarify the characteristics and interrelationships of the three types of methods. In the actual security analysis, there are still some limitations in the above method of information synthesis. Conclusion The application of probability theory, evidence theory and probability theory in the information synthesis of security analysis needs to be further studied. The new information synthesis technology needs to be developed.
