手机图形密码的研究是信息安全的一个热点课题。为此提出一种手机图形密码的安全性分析方法。该方法首先将具体的实际问题抽象成计算机可处理的模型，利用拓扑学的知识，遍历图形中的点以得到所有可能的密码；然后通过伪代码的形式，给出手机图形密码生成器的具体算法，最后，分析图形密码的安全性。实验结果表明，该方法可以有效地给出手机图形密码的安全性分析。同时，还给出了密码生成器的算法和手机图形密码数量统计的方法。

The study on graphical password of mobile is a hot topic in the field of information security. For this reason, this paper proposes a method of security analysis of mobile based on graphical password. This method firstly abstracts a model to be processed by computer from the specific problem in reality. Then, the knowledge of topology is used to traverse the graphical model to obtain all possible passwords. Then, the generation algorithm of graphical password is provided in the form of pseudo-code. Finally, the security analysis for graphical password is put forward based on the above works. Experimental results indicate that the method proposed by this paper can be used to analyze the security of graphical password for mobile, effectively. Meanwhile, this paper also provides the algorithm for generating password, and statistical approach for calculating the numbers of the generated password.
