英文摘要：

At present, public WiFi meets the practical requirement for the Internet access and rapidly develops, but it exists many security problems. Researches of public WiFi security detection technology is described in this paper. Combined with the convenience and practical detection effect, a public WiFi security detection system has been researched and implemented, run on mobile terminals and is easyte use. Meanwhile, its implementation principle is explained in the paper. After testing and evalua- tion, the system is proved to be easy to use, can meet the practical requirements, and has a certain application value for detec- tion and prevention of public WiFi security problems.
