Alice Meets Bob:“双用户”环境下无线设备配对方法的可用性比较研究

Alice Meets Bob: A Comparative Usability Study of Wireless Device Pairing Methods for a "Two-User" Setting

Arun Kumar, Nitesh Saxena, Ersin Uzun

摘要:

当用户想要在他们的设备之间建立无线通信时,必须首先引导信道。为了防止对通信的任何恶意控制或窃听,期望信道被认证和保密。在两个先前未关联的设备之间建立安全通信信道的过程被称为“安全设备配对”。当没有先前的安全上下文时,例如,共享秘密、公共密钥服务器或公钥证书,设备配对需要用户参与该过程。这个想法通常涉及利用辅助的人类可感知的信道来验证通过不安全的无线信道交换的数据。我们观察到,先前研究的重点主要限于单个用户控制两个设备的配对场景。在本文中,我们考虑更一般和新兴的“双用户”场景,其中两个不同的用户在各自的设备之间建立配对。尽管文献中存在许多配对方法,但其中只有少数适用于两个用户设置。我们提出的第一项研究,以确定实用的方法,为两个用户配对的情况下,并比较评估这些方法的可用性。我们的研究结果确定了最适合用户的方法,在效率,容错性,当然,可用性。我们的工作揭示了配对方法在新兴的两个用户场景中的适用性和可用性,这是一个迄今为止被忽视的话题。

英文摘要:

When users want to establish wireless communication between/among their devices, the channel has to be bootstrapped first. To prevent any malicious control of or eavesdropping over the communication, the channel is desired to be authenticated and confidential. The process of setting up a secure communication channel between two previously unassociated devices is referred to as "Secure Device Pairing". When there is no prior security context, e.g., shared secrets, common key servers or public key certificates, device pairing requires user involvement into the process. The idea usually involves leveraging an auxiliary human-perceptible channel to authenticate the data exchanged over the insecure wireless channel. We observe that the focus of prior research has mostly been limited to pairing scenarios where a single user controls both the devices. In this paper, we consider more general and emerging "two-user" scenarios, where two different users establish pairing between their respective devices. Although a number of pairing methods exists in the literature, only a handful of those are applicable to the two-user setting. We present the first study to identify the methods practical for two-user pairing scenarios, and comparatively evaluate the usability of these methods. Our results identify methods best-suited for users, in terms of efficiency, error-tolerance and of course, usability. Our work sheds light on the applicability and usability of pairing methods for emerging two-user scenarios, a topic largely ignored so far.
