中文摘要：

为了解决云计算框架所面临的威胁，提出了针对私有云间隐私泄漏攻击的最优攻击选择算法。该方法根据最优攻击选择算法选择攻击对象，然后发起攻击，攻击造成私有云间的路径发生拥塞，迫使私有云改变路径；与此同时发起对其他路径的攻击，进而控制其他路径，从而实现对私有云间通信的控制，通过对被控制路径的监听完成隐私窃取，最后对攻击方法进行了实现。实验结果表明，该方法能够有效地控制私有云间的通信，从而达到对私用云侦测的目的，为保护私有云间信息的攻击提供参考。

英文摘要：

In order to solve the threats in cloud computing framework,the algorithm of optimal selection attacking on private clouds priva-cy leaking is proposed. Using the optimal selection algorithm to choose attacked object and attack,causing the path congestion between the private clouds,forcing the clouds to change another communication path. Simultaneously,attack the other paths,and then control the other paths,so as to realize the control of communication between the private clouds,completing privacy stealing by monitoring the con-trolled paths. Finally,the attack method is realized. The experimental results show that this method can effectively control the communica-tion between private clouds,so as to achieve the aim of the private cloud detection,providing an reference for protecting the information between private cloud to be attacked.
