在验证密码的正确性后，基于击键动态的认证KDA系统将验证相应的击键特征。它为遭受猜测和肩窥攻击的基于字母数字和基于个人识别号码的身份验证方案提供了额外的安全验证。除了KDA方案中原有的时间特征之外，在触摸屏手持移动设备中还发现了两个新颖的击键特征，即“压力”特征和“尺寸”特征。为低功耗移动设备构建计算高效的统计分类器来验证用户的身份。本文分析了以下特征组合： 1.时间特征； 2.时间特征和压力特征； 3 时间特征和尺寸特征； 4 所有功能组合在一起。结果表明，尺寸特征或压力特征可以有效地促进KDA系统在触摸屏移动设备的基于个人识别码的认证方案中的实用性。时间特征和压力特征的组合是对用户进行身份验证的最佳组合。版权所有 © 2013 约翰·威利父子有限公司
After verifying the correctness of the password, the keystroke dynamics-based authentication KDA system will verify the corresponding keystroke features. It provides additional security verification for alphanumeric-based and personal identification number-based authentication schemes that suffer from guessing and shoulder surfing attacks. Except for the original time features in the KDA schemes, two novel keystroke features are found in touch screen handheld mobile devices, which are called "pressure" features and "size" features. A computation efficient statistical classifier is built for low-power mobile devices to authenticate the user's identity. This paper analyzes the following combinations of features: 1 time features; 2 time features and pressure features; 3 time features and size features; and 4 all features combined. The result shows that the size features or the pressure features can effectively promote the utility of the KDA system in personal identification number-based authentication schemes for touch screen handled mobile devices. The combination of time features and pressure features is the best one for authenticating users. Copyright © 2013 John Wiley & Sons, Ltd.
