本研究提出适用于虚拟现实的自适应方向身份验证（ADBA），经66人2-3周远程纵向对比实验，其记忆性更优、任务负荷更低，能平衡效率、记忆性与安全性，优于传统6位PIN。
AI 中文摘要
我们提出了自适应方向身份验证（ADBA），这是一种适用于虚拟现实的基于知识的身份验证方法，通过强制基于虚拟环境情境创建密码，同时在身份验证期间支持基于情境和数字的输入，在时间上分离用户需求。该设计优先考虑新密码的记忆性，并提供高效且易记的选项以支持用户不断变化的需求。我们开展了一项包含66名参与者的远程纵向研究，在2至3周内将ADBA与6位数字个人识别码（PIN）进行比较。结果表明，ADBA实现了更优的记忆性和更低的感知任务负荷。有趣的是，研究中没有参与者选择通过数字输入，但尽管客观输入时间更长，他们仍认为ADBA具有很高的效率。ADBA还通过随机生成的数字表示提供了安全优势，不过在特定虚拟环境中观察到一定程度的密码同质性。我们的研究结果表明，ADBA相比传统PIN具有显著优势，在研究考虑的使用场景下成功解决了效率、记忆性和安全性之间的权衡问题。
英文摘要
We present Adaptive Direction-Based Authentication (ADBA), a knowledge-based authentication method for Virtual Reality that decouples users' needs temporally by enforcing password creation based on virtual environment context while supporting both context- and digit-based entries during authentication. This design prioritizes memorability for new passwords and offers both efficient and memorable options to support users' evolving needs. We conducted a remote longitudinal study with 66 participants comparing ADBA against 6-digit PINs over 2-3 weeks. The results demonstrated that ADBA achieved superior memorability and lower perceived task load. Interestingly, no participant chose to enter via digits in the study, yet they still perceived ADBA to be highly efficiency despite longer objective entry times. ADBA also provided security benefits through randomly-generated digit representations, though some degree of password homogeneity was observed in specific virtual environments. Our findings suggest that ADBA offers solid advantages to the traditional PINs, and successfully addresses the tradeoffs between efficiency, memorability, and security under the usage scenarios considered in the study.
