开源智能终端占智能终端市场的绝对优势，基于开源智能终端的应用层出不穷，但与此同时，其安全隐患也一样触目惊心。该文以典型社交网络APP登录认证为例，通过逆向分析当今市场上的主流Android应用，分析登录认证实现过程的机理，对登录认证机制进行安全性评估，挖掘基于现有认证机制的安全漏洞，并针对所发现的安全问题提出了登录认证机制改进方案，总结出一套安全实用的登录认证实践方案，有效提高移动智能终端系统的安全性。
Open source intelligent terminals have many advantages in intelligent smart phones with endless applications of intelligent terminals based on open source codes. However, there are also many security risks for applications using intelligent terminals. This study analyzes the login authentication of a mainstream Android application in today's market by reverse analysis. The security flaws for current login authentication mechanisms are evaluated to discover potential security vulnerabilities in intelligent terminal devices. An improved for login authentication scheme is then given which effectively improves the security of intelligent terminal systems.
