【摘要】：随着科学技术的发展,新型装备系统结构日趋复杂化,除了系统内部组件数量的剧增之外,各分系统之间的连接关系也越来越复杂,传统的系统安全性评估方法已经不能完全适用于复杂化装备系统。以复杂网络知识为依托、对复杂装备系统的安全性进行评估为目的,构建了以装备分系统为节点、以分系统之间的信息交互关系为连接边的复杂网络模型。针对不同网络拓扑结构对系统安全性的影响,对不同属性节点比例对系统安全性影响进行了对比分析,突出了分系统之间的连接关系对装备系统安全性的影响,为信息化条件下的复杂装备系统安全性评估提供了依据。
[Abstract]:With the development of science and technology, the structure of the new equipment system is becoming more and more complicated. Besides the sharp increase in the number of components within the system, the connection relationship among the subsystems is becoming more and more complex. The traditional system security evaluation method can not be fully applied to complex equipment system. Based on the complex network knowledge, the security of complex equipment system is evaluated, and the equipment sub-system is constructed as the node. The complex network model based on the information exchange between subsystems is used as the connection edge. According to the influence of different network topology on system security, the effect of different attribute node ratio on system security is compared and analyzed. The influence of the connection relationship between subsystems on the security of equipment system is highlighted, which provides the basis for the security evaluation of complex equipment system under the condition of information technology.
