摘要
医用离心机具有远程数据存储功能,其软件产生大量的数据需要频繁联系远程服务器,服务器给出被动选择防护方案,这种方式弊端明显。因此,开展基于离心机软件的本地溯源防御研究。根据软件日志中的主体对象类、客体对象类和事件类,建立有向异构属性图,依据节点的信用等级,基于最短路径溯源窃密攻击。结合溯源得到的窃密攻击特征,通过求取博弈模型的精炼贝叶斯纳什均衡,选取出最优的防御策略,反馈给服务器。通过5种极具代表性的窃密攻击溯源防御实验结果显示,所提方法溯源错误次数不足总次数的0.01%,防御策略能够应对各类窃密攻击,也具有高盈利性和弱化威胁的能力。
Medical centrifuges have remote data storage capabilities,and their software generates a large amount of data that requires frequent contact with remote servers.The servers provide passive selection protection solutions,which have obvious drawbacks.Therefore,research on local traceability defense based on centrifuge software is being carried out.Based on the subject object class,object object object class,and event class in the software log,establish a directed heterogeneous attribute graph,and based on the credit rating of nodes,trace the source of secret theft attacks using the shortest path.By combining the characteristics of stealing secrets obtained through tracing,the refined Bayesian Nash equilibrium of the game model is obtained,and the optimal defense strategy is selected and fed back to the server.Through five representative experiments on tracing and defending against theft attacks,the results show that the proposed method has less than 0.01%of the total number of tracing errors.The defense strategy can cope with various types of stealing secrets and also has high profitability and the ability to weaken threats.
