Biswal, Milan, Misra, Satyajayant, Tayeen, Abu S..  2020.  Black Box Attack on Machine Learning Assisted Wide Area Monitoring and Protection Systems. 2020 IEEE Power Energy Society Innovative Smart Grid Technologies Conference (ISGT). :1–5.
The applications for wide area monitoring, protection, and control systems (WAMPC) at the control center, help with providing resilient, efficient, and secure operation of the transmission system of the smart grid. The increased proliferation of phasor measurement units (PMUs) in this space has inspired many prudent applications to assist in the process of decision making in the control centers. Machine learning (ML) based decision support systems have become viable with the availability of abundant high-resolution wide area operational PMU data. We propose a deep neural network (DNN) based supervisory protection and event diagnosis system and demonstrate that it works with very high degree of confidence. The system introduces a supervisory layer that processes the data streams collected from PMUs and detects disturbances in the power systems that may have gone unnoticed by the local monitoring and protection system. Then, we investigate compromise of the insights of this ML based supervisory control by crafting adversaries that corrupt the PMU data via minimal coordinated manipulation and identification of the spatio-temporal regions in the multidimensional PMU data in a way that the DNN classifier makes wrong event predictions.

Chakraborti, Asit, Amin, Syed Obaid, Azgin, Aytac, Misra, Satyajayant, Ravindran, Ravishankar.  2018.  Using ICN Slicing Framework to Build an IoT Edge Network. Proceedings of the 5th ACM Conference on Information-Centric Networking. :214–215.
We demonstrate 5G network slicing as a unique deployment opportunity for information centric networking (ICN), by using a generic service orchestration framework that operates on commodity compute, storage, and bandwidth resource pools to realize ICN service slices. In this demo, we specifically propose a service slice for the IoT Edge network. ICN has often been considered pertinent for IoT use due to its benefits like simpler stacks on resource constrained devices, in-network caching, and in-built data provenance. We use a lightweight ICN stack on IoT devices connected with sensors and actuators to build a network, where clients can set realistic policies using their legacy hand-held devices. We employ name based authentication protocols between the service end-points and IoT devices to allow secure onboarding. The IoT slice co-exists with other service slices that cater to different classes of applications (e.g., bandwidth intensive applications, such as video conferencing) allowing resource management flexibility. Our design creates orchestrated service Edge functions to which the clients connect, and these can in turn utilize in-network stateless functions to perform tasks, such as decision making and analytics using the available compute resources efficiently.

Tourani, Reza, Misra, Satyajayant, Mick, Travis.  2016.  Application-Specific Secure Gathering of Consumer Preferences and Feedback in ICNs. Proceedings of the 3rd ACM Conference on Information-Centric Networking. :65–70.

The shift from the host-centric to the information-centric paradigm results in many benefits including native security, enhanced mobility, and scalability. The corresponding information-centric networking (ICN), also presents several important challenges, such as closest replica routing, client privacy, and client preference collection. The majority of these challenges have received the research community’s attention. However, no mechanisms have been proposed for the challenge of effective client preferences collection. In the era of big data analytics and recommender systems customer preferences are essential for providers such as Amazon and Netflix. However, with content served from in-network caches, the ICN paradigm indirectly undermines the gathering of these essential individualized preferences. In this paper, we discuss the requirements for client preference collections and present potential mechanisms that may be used for achieving it successfully.
