M.S. Paper Title: Rethinking Access Control and Authentication for the
Home Internet of Things (IoT)

Abstract:
Computing is transitioning from single-user devices to the Internet of
Things (IoT), in which multiple users with complex social
relationships interact with a single device. Currently deployed
techniques fail to provide usable access-control specification or
authentication in such settings. In this paper, we begin reenvisioning
access control and authentication for the home IoT. We propose that
access control focus on IoT capabilities (i.\,e., certain actions that
devices can perform), rather than on a per-device granularity. In a
425-participant online user study, we find stark differences in
participants' desired access-control policies for different
capabilities within a single device, as well as based on who is trying
to use that capability. From these desired policies, we identify
likely candidates for default policies. We also pinpoint necessary
primitives for specifying more complex, yet desired, access-control
policies. These primitives range from the time of day to the current
location of users. Finally, we discuss the degree to which different
authentication methods potentially support desired policies.

Weijia's advisor is Prof. Blase Ur
