摘要
Abstract
According to usage status of graphical passwords,there is a fatal problem in the security of graphical passwords that it is easy to be attacked.In order to solve this problem,a new multi-stroke system recommended graphic password scheme(MSSRGP)is designed.In this scheme,the graphics of the graphics password of system were connected or non-connected directed graphs and the graphical password mode recommended by system was one-to-one mode.If a certain graphic password was selected by the user,it would not be recommended by the system,which improved the ability to resist brute force attacks and dictionary attacks.To verify the practicality and security in graphical password schemes,students majoring in computer were organized to test password and analyze the collected test data.The results show that the MSSRGP scheme has good practicability and high recognition rate when its graphical password has 2 strokes and 3 strokes.关键词
