摘要
提出了一种新的基于多图形选择的图形口令机制。与现存的基于多图形选择的图形口令相比,文中所提出的新机制采用敲击键盘选择口令图片,代替了以往由鼠标点击的选择方式,其优点在于可有效地防止肩窥攻击,并能抵御交叉攻击,增加了口令机制的安全性。实验证明,该机制具有较好的安全性和可用性。
A novel g graphical password scheme based on choosing multiple images is proposed in this paper.Different from the existing graphical password schemes,this scheme uses the click on keyboard to choose the pass-icons in stead of the mouse-click manner.The advantage of this scheme is its good resistance to the shoulder surfing attack and intersection attack so that the security of the scheme is enhanced greatly.
