Using a 2DST waveguide for usable, physically constrained out-of-band Wi-Fi authentication

Abstract

This paper proposes using a 2D waveguide for a novel means of authentication in public Wi-Fi infrastructures. The design of the system is presented, and its practicability and usability is comparatively discussed with that of five other tag and context based authentication schemes, two of which have not been previously realized. In accordance with the presented application scenarios, all of the schemes were implemented in a platform-independent fashion built on web technology.

A Comparative Study to Evaluate the Usability of Context-Based Wi-Fi Access Mechanisms

“…In addition to token based methods we adapted we adapted two relevant OOB techniques and included a recent approach using surface-con ned Wi-Fi [3] as context based methods. The methods were selected to ful ll the following constraints:…”

“…An alternative would have been NFC-based Wi-Fi Protected Setup, which we refrained from using due to known vulnerabilities [19] and lacking personalizability. 2DST Sheet A detailed description of the TwoDimensional Signal Transmission (2DST) waveguide sheet was published in previous work [3]. To log on, users connect to the open Wi-Fi and the captive portal page prompts them to place the device on the sheet (see Figure 1) and acknowledge the coupling.…”
