【摘要】：对协同式网络攻击下抗毁性的优化研究,能够有效保证网络通信能力以及安全运行。对网络抗毁性的分析,需要将网络故障节点负荷分配给其他相邻节点,计算网络的抗毁性度量指标,完成网络受到攻击时抗毁性优化。传统方法先获取整个网络节点对之间的连接紧密程度,然后利用网络节点环路系数反应网络节点可选的路径数目,但忽略了计算网络抗毁性度量指标,导致网络抗毁性优化精度偏低。提出基于综合效率指标的协同式网络攻击下抗毁性建模方法,首先计算通信网络中任意两个网点之间的直接连接距离和最短路径长度,以及平均路径损失度。其次通过计算通信网络的综合效率指标来衡量通信网络的破坏程度。然后将协同式网络攻击下的通信网络故障节点负荷分配给其他相邻节点,计算网络的抗毁性度量指标。仿真结果证明,所提方法能够保证网络的有效通信效率,减小网络的毁坏率。
[Abstract]:The research on the invulnerability of cooperative network attack can effectively guarantee the network communication ability and security operation. For the analysis of network survivability, it is necessary to distribute the load of network fault nodes to other adjacent nodes, calculate the network survivability metrics, and finish the invulnerability optimization when the network is attacked. The traditional method firstly obtains the connection tight degree between the whole network node pairs, then uses the network node loop coefficient to reflect the network node optional path number, but neglects to calculate the network invulnerability metric index. As a result, the accuracy of network survivability optimization is on the low side. A modeling method of invulnerability under cooperative network attack based on comprehensive efficiency index is proposed. Firstly, the direct connection distance and the shortest path length between any two nodes in the communication network are calculated, as well as the average path loss degree. Secondly, the damage degree of communication network is measured by calculating the comprehensive efficiency index of communication network. Then the load of communication network failure nodes under cooperative network attack is allocated to other adjacent nodes to calculate the network survivability metrics. Simulation results show that the proposed method can ensure the effective communication efficiency of the network and reduce the destruction rate of the network.
