Privacy-Aware Wearable-Assisted Continuous Authentication Framework

Whether it is one-factor or MFA, a one-time login process does not guarantee that the identified user is the real user throughout the login session. Even if it is an insider who has been authorized once, a forever access is provided in most cases not to interrupt the current user. Hence, an authentication which re-verifies the user periodically without breaking the continuity of the session is vital. In this project, we introduce a Wearable-Assisted Continuous Authentication framework called WACA, where a wearable device (e.g., smartwatch) is used to authenticate a computer user continuously utilizing the motion sensors of the smartwatch.

SaINT: Sensitive Information Tracking in IoT Applications

Broadly defined as the Internet of Things (IoT), the growth of commodity devices that integrate physical processes with digital connectivity has had profound effects on society—smart homes, personal monitoring devices, enhanced manufacturing and other IoT applications have changed the way we live, play and work. Yet extant IoT platforms provide few means of evaluating the use (and potential misuse) of sensitive information. In this project, we present SaINT, a tool for analyzing sensitive data leakage in IoT implementations. SaINT operates in three phases; (a) translation of platform-specific source code into an IR modeling sensor-computation-actuator structures, (b) identifying sensitive sources and sinks, and (c) performing static analysis to identify sensitive data leakage.

6thSense: Securing Sensory Side-Channels in Cyber-Physical Systems and IoT Devices and Applications

Modern devices have become “smart” in recent years with the advancement of modern electronics and wireless communication systems. Smart devices such as smartphone, smartwatch, fitness trackers, etc. are equipped with high precision sensors, empowering them to gather information about user characteristics as well as the surrounding environment. These sensor-enriched devices have opened a new domain of sensing-enabled applications. With the rapid growth sensing-enabled applications, smart devices are integrated in every possible application domain, from home security to health care to military. Some applications can even learn characteristics of users using sensor data and take automatic decisions to improve the user experience.

Compromised Device Detection

The core concept of the smart grid is the realization of two-way communications between smart devices. The integration of complex and heterogeneous networks as well as their devices into the smart grid must be done not only in an efficient but also a secure manner. Nonetheless, with all its dependency upon device operations and communications, the smart grid is highly vulnerable to any security risk stemming from devices. Especially, the use of compromised devices can wreak havoc on the smart grid’s critical functionalities and can cause catastrophic consequences to the integrity of the smart grid data and/or users’ privacy.
