基于社会网络分析的共享密码监督方法研究

为了对密码共享进行监督和管理，基于社会网络分析（SNA： Social Network Analysis）方法，对网络用户密码共享行为的监督技术进行了研究，提出了一种寻找密码传播路径的方法。结合图论中有向图及路径的相关理论，对简化后的密码传播最短路径算法进行描述。该方法通过扫描电子邮箱库中系统管理员邮箱与所有外部电子邮箱之间的最短路径
，找出密码共享可能的传播路径，以便对用户密码的共享行为进行监督。结果表明，该方法可对当前系统的密码安全状态进行评估，对密码共享行为所造成的保密信息泄露起到一定的预防作用。

Research of Monitoring Method of Password Sharing Based on Social Network Analysis

Focused on the monitoring and management problem of the password sharing,based on the method of SNA(Social Network Analysis),researching the technology of monitoring method of customers password sharing,a method of finding the path of password sharing is improved.According to the related theory of directed graph and route in graph theory,the main arithmetic of the shortest path of password sharing is described.Depended on scanning the shortest path of e-mail sending from system administrator e-mail box to outside e-mail box,the possible transmit path of password sharing may be found and the behavior of password sharing may be monitored.By this method,the status of password security can be evaluated and the private information leakage may be prevented.
