摘要:
 密码认证目前仍然是移动终端主流身份认证方式之一。移动终端由于其使用环境的复杂性，密码容易遭受肩窥攻击。针对这种情况，文中吸取Pass-Object经典图形密码方案加入干扰图形的设计思想并加以改进，提出了一种面向移动终端的抗肩窥图形密码方案，方案以字符和颜色为基础生成图形密码。方案的设计完全符合触摸式移动终端用户的使用习惯，整个认证过程用户只需在触摸屏上点击即可完成操作。安全性分析数据表明：方案在密码空间和抗意外登陆方面都安全性良好，而且可有效抵御登陆过程被多次录制的肩窥攻击。
Abstract:
 Passwords authentication is still one of the main authentication modes for mobile terminal. Mobile terminal is vulnerable to shoulder surfing attack because of using in complex environments. Absorbing the design thought of adding interference graph from the pass-object graphical password scheme,a shoulder surfing resistant graphical passwords scheme for mobile terminal is proposed,in which the graphical passwords are generated by characters and colors. In the scheme,just by clicking the screen user can complete the whole log-in phase,the scheme design completely conforms to the use habit of touch type mobile terminal user. The security analysis shows that the scheme has good security in the password space and accidental login resistance,and can effectively resist the shoulder surfing attack in that the login process is recorded repeatedly.
