| 摘 要： | D-S证据理论是不确定推理的一种重要方法,在许多方面都得到了广泛的应用。针对D-S证据理论在网络安全态势感知的数据融合过程中的应用,就多源数据的证据组合结果与直觉相悖的问题进行深入研究,提出了一种新的解决方案。该方案通过支持度的思想对冲突证据源进行修正以达到解决证据冲突的目的。最后,以网络安全态势感知环境为背景进行数值算例,证明了所提方法的可行性。

| Abstract: | D-S evidence theory is a kind of important uncertainty reasoning methods,has been widely used in many ways.The paper mainly studied application of D-S evidence in the data integration process of network security awareness.And researching contradictions between combination results of multi-source evidence and intuition,it put forward a new solution.The scheme revises the origin of conflict evidence through using the support ideas in order to solve the conflict of evidence.Finally,through a numerical example in the network security situational awareness environment,it proved the feasibility of this method. |
