We present CrossSense, a novel system for scaling up WiFi sensing to new environments
and larger problems. To reduce the cost of sensing model training data collection …

Secure device pairing (SDP) schemes have been developed to facilitate secure
communications among smart devices, both personal mobile devices and Internet of Things …

Two-factor authentication protects online accounts even if passwords are leaked. Most
users, however, prefer password-only authentication. One reason why twofactor …

Relay attacks generally occur between two entities that communicate with each other
through wireless means. When a relay attack between a honest prover and a honest verifier …

Solutions for pairing devices without prior security associations typically require users to
actively take part in the pairing process of the devices. Scenarios involving new types of …

Many mobile and wireless authentication systems are prone to relay attacks whereby two
non co-presence colluding entities can subvert the authentication functionality by simply …

Physical-layer attacks allow attackers to manipulate (spoof) ranging and positioning. These
attacks had real-world impact and allowed car thefts, executions of unauthorized payments …

Reducing user burden underlying traditional two-factor authentication constitutes an
important research effort. An interesting representative approach, Sound-Proof, leverages …

Voice controlled interfaces have vastly improved the usability of many devices (eg, headless
IoT systems). Unfortunately, the lack of authentication for these interfaces has also …

Mobile device authentication has been a highly active research topic for over 10 years, with
a vast range of methods proposed and analyzed. In related areas, such as secure channel …
