摘　　要：虚拟网络节点选取防护策略模型没有充分考虑节点之间相关指标的差异,造成防护策略安全性低、可信度指标简单,为此,提出一种虚拟网络攻击下节点选取防护策略模型设计方法。根据各节点关键度和可信度的不同,获取节点选取防护策略,通过节点收缩方式对节点的关键度施行计算,通过D-S证据理论对虚拟网络攻击下选取节点的可信度进行评价。分析了虚拟网络的安全需求,在此基础上,通过信任评价关键节点选取策略构建防护策略模型。实验结果表明:通过建立模型选取的节点能有效实现虚拟网络防护,用户满意度高,实用性强。The virtual network node selection protection strategy model did not fully consider the differences of relevant indicators between nodes,and it will result in low security of protection strategy and the simple credibility index. A design method of node selection protection strategy model under virtual network attack was proposed in this paper. According to the different key degree and reliability of each node,the node selection protection strategy was obtained. The key degree of nodes through the node contraction mode was calculated. Moreover,the credibility of node selection was evaluated through the D-S evidence theory under the virtual network attack. Then,the security requirements of virtual network were analyzed. On this basis,the protection strategy model was built by the key node selection strategy of trust evaluation. Experimental result shows that the establishment of nodes selected by model can effectively realize the virtual network protection. The higher the user’s satisfaction is the stronger the practicability is.
