PrivacyGuard: Towards Flexible Edge Privacy Framework for IoT and Mobile Applications using Extreme SDN

With the current significant penetration of mobile devices (i.e. smartphones and tablets) and the tremendous increase in the number of apps, they have become an indispensable part of our lives. Among these different applications, there is a significant growth of sensitive applications such as personal health applications, personal financial applications, home monitoring applications, etc. In addition, with the significant growth of Internet-of-Things (IoT) devices, smartphones are widely considered as Internet gateways to these IoT devices through using the corresponding IoT applications on smartphones. Mobile devices mostly use wireless LANs (WLANs) (i.e., WiFi networks) as the prominent network interface to the Internet. However, due to the broadcast nature of WiFi links, wireless traffics are exposed to any eavesdropping adversary within the WLAN. Despite WiFi encryption, studies show that app-usage information could be inferred from the encrypted wireless traffic. We believe this application usage information is a serious privacy and security concern for the mobile users. In addressing this security concern, we design and develop a light-weight flexible programmable privacy management framework, called PrivacyGuard. PrivacyGuard is inspired by the vision of pushing the Software Defined Network (SDN)-like paradigm all the way to wireless network edge to create one or more vertical network slicing between mobile devices and WiFi APs/Proxy server, and apply set of privacy preserving policies on the traffic based on the application, user, device, and network conditions and requirements. In this project, we demonstrate and evaluate a prototype of PrivacyGuard framework in Android OS. Results show that PrivacyGuard introduces a negligible performance overhead and minor impact on battery life while providing flexible policies to protect the wireless network communication of sensitive applications.

ExtremeDataHub: Towards a Secure and Flexible Personal Data Platform on the Edge

The significant growth and penetration of smart and IoT devices come along with a tremendous increase in the number of smart and IoT applications. These various applications, which support various domains and services, generate and access different data patterns such as periodic, event-based, realtime and continuous data. For example, sensor-based applications like pacemaker, motion detection, temperature sensing, glucose monitoring generate and access data on periodic bases. Event-based applications generate and access data only when the device state changes such as when a light bulb is turned off or when a door lock is unlocked. On the other hand, video/audio monitoring applications continuously generate and access streams of data. Consequently, these different applications result in diverse traffic characteristics that require different performance levels of reliability, loss, and latency. To cope with this various traffic characteristics and requirements, it is now necessary to have greater visibility and control over the traffic generated from smart and IoT devices in order to guarantee an optimized performance of smart and IoT applications as well as high quality of experience to users. In this project, we aim to design and develop ExtremeDataHub platform; an open-source, flexible, and programmable networked edge device that collates and mediates access to our sensitive and personal data, under the data subjects control as well as to cope with various characteristics and requirements of smart and IoT applications that access this data in order to provide better performance and quality of experience to users. ExtremeDataHub will be developed as a networked edge device (e.g., could reside within the home wireless access point or as a standalone device) that enable individuals to control and manage their sensitive and personal data as well as to provide flexibility and controllability to support the various characteristics and requirements of different data access flows generated by smart and IoT applications for higher performance and quality of experience. Moreover, this project aims at exploring how ExtremeDataHub could be utilized in smart home, smart healthcare, and smart cities domains.

Scalable and Efficient Communication for Internet of Things (IoT)

In this project, the focus group is addressing the challenges posed by the massive growth to the wireless industry. This project aims to develop novel IoT architectures and algorithms to enable large-scale IoT deployments. In particular, it introduces holistic, cross-layer design framework and protocols for improving spectral/energy efficiency and latency of massive IoT networks. We specifically work on core network connection efficiency for IoT networks which requires rethinking the core network functions for connection of massive IoT as they are not designed considering the IoT traffic characteristics. The project will develop and rigorously study an aggregation based connectivity model to manage multiple IoT device traffic using the same resources (i.e., bearers). For efficient groupings of the IoT devices that will share the same connection, researchers will use efficient clustering methods, while giving preference to the interference minimizing groups.

Rapid and Resilient Critical Data Sourcing for Public Safety and Emergency Response

In this project, the focus group is investigating secure, rapid and resilient methods for public safety and emergency response applications. In emergency scenarios, the communication between law enforcement and citizens should be robust and resilient as the network could be congested or the underlying cellular infrastructure is damaged or temporarily lost. This project addresses these challenges by introducing a novel framework that integrates various technologies (e.g., Device-to-Device (D2D) communication, Global Environment for Network Innovations (GENI) network slices) and tools for modeling and operation of large-scale crowd sourcing-based emergency response systems to make them more resilient and robust.
