SUMMARY:ECE Seminar: Siddhartha Ghosh
DESCRIPTION:Location: 136 ISEC \nAbstract: \nAcoustic waves are well-suited for a variety of signal processing applications including RF filtering and optical modulation. Advances in material and fabrication capabilities have enabled the demonstration of chip-scale subsystems in which phonons can exhibit strong interactions with a variety of other physical domains. This talk will discuss developments in two of these areas\, specifically acousto-electric (AE) amplification and acousto-optic modulation in piezoelectric materials. Recently\, non-reciprocal and switchable delay lines have generated great interest for applications in full duplex radio networks. As a result\, AEbased approaches to mitigating signal interference in the RF front end have been sought. Here we will consider the development of a low sheet density AlGaN/GaN heterostructure on sapphire substrates to demonstrate AE amplification of Rayleigh waves. In addition\, the use of atomic layer deposition (ALD) assisted wafer bonding technology is demonstrated for integrating thin film silicon on bulk lithium niobate to produce stronger non-reciprocity. These results are showcased with regard to implementation in analog correlators with large processing gain. In addition\, we will discuss the development of piezoelectrically-actuated acousto-optic modulators in the aluminum nitride (AlN) material system. Optical coupling to AlN thin films is demonstrated in the telecommunications bands\, enabling monolithic integration of photonic and bulk acoustic resonators. Overlap of these fields enables efficient conversion from RF to optical frequencies\, with applications in integrated microwave photonics and quantum information transfer. \nBio: \nSiddhartha Ghosh is currently a member of the technical staff in the RF Technology Group at MIT Lincoln Laboratory\, Lexington\, MA. He received the B.S. degree in from Cornell University in 2007\, the M.S.E. degree from the University of Pennsylvania in 2011 and the Ph.D. degree from Carnegie Mellon University in 2015\, all in electrical engineering. From 2007 to 2009 he was a Hardware Engineer with Lockheed Martin Corporation in Syracuse\, NY. He is the author of 20 journal and conference publications and coinventor of an issued patent. Since 2018\, he has served on the Technical Program Committee (TPC) for the IEEE International Frequency Control Symposium. His research interests include piezoelectric MEMS\, optomechanical resonators\, oscillator-based computing and acousto-electronic devices.

SUMMARY:ECE Seminar: Stephanie Gil
DESCRIPTION:Abstract:  Multi-robot systems are becoming more pervasive all around us\, in the form of fleets of autonomous vehicles\, future delivery drones\, and robotic teammates for search and rescue.  As a result\, it becomes increasingly critical to question the robustness of their coordination algorithms to reliable information exchange\, security threats and/or corrupted data. This talk will focus on the role of controlled mobility and information exchange for enhancing situational awareness and security of these systems. Specifically\, we will discuss our work in using robot mobility to realize reliable and adaptive information exchange that supports coordination objectives\, the role of communication for quantifying trust in several important multi-robot algorithms\, and the use of information exchange to divulge new information about the environment.  We will study the vulnerabilities of important multi-robot algorithms such as consensus and coverage to malicious or erroneous data and we demonstrate the potential of communication to thwart certain attacks\, for example\, the Sybil Attack\, on these algorithms. We will present both a theoretical framework and experimental results\, for provably securing multi-robot distributed algorithms through careful use of communication.  Lastly\, we will present promising results on new communication-centric methods for outlier rejection and active rendezvous in distributed mapping tasks. \n  \nBio: Stephanie is an Assistant Professor in the School of Computing\, Informatics\, and Decision Systems Engineering at Arizona State University (Jan 2018). Her work centers around trust and coordination in multi-robot systems for which she has been granted an NSF CAREER award (see Improving Mission Intelligence within Fleets of Robots) and has been reviewed in MIT News (see some of her work in security for multi-robot systems and human-robot EEG based communication) as well as several other news outlets including Forbes and the Financial Times (full list on her website).  Prior\, she was a research scientist in the Computer Science and Artificial Intelligence Lab (CSAIL) at MIT where she also completed her Ph.D. work (2014) on multi-robot coordination and control and M.S. work (2009) on system identification and model learning. At MIT she collaborated extensively with the wireless communications group NetMIT\, the result of which were two U.S. patents recently awarded in adaptive heterogeneous networks for multi-robot systems and accurate indoor positioning using Wi-Fi.  She completed her B.S. at Cornell University in 2006.

SUMMARY:Electrical and Computer Engineering Seminar: Nader Sehatbakhsh
DESCRIPTION:Abstract: \nThis decade has already seen a significant surge in the number of cyber-attacks. With the exponential growth of computers in numbers\, due to the rise of cyberphysical systems (CPS) and internet-of-things (IoT) devices\, and their ever-increasing importance in controlling critical tasks\, it is expected that cybersecurity and data privacy become even more serious problems in the next decade. To this end\, I will present our methods and findings in designing secure computing systems using two main themes: 1) by discovering\, modeling\, and mitigating side-channels\, and 2) by leveraging side-channels for useful purposes such as debugging and security monitoring. Specifically\, in this talk\, I will first present our novel method on debugging and securing resource-limited devices such as embedded systems\, CPSs\, and IoTs by externally monitoring these devices using analog side-channels (e.g.\, electromagnetic emanations\, power fluctuations\, etc.) that are unintentionally created by these devices. I will describe how analog side-channel signals can be also leveraged for profiling\, intrusion detection\, and establishing a trusted execution environment (TEE) on resource constrained devices without incurring any overhead or requiring any hardware support on the monitored device and/or any intrusion to its functionality. In the second part of the talk\, I will demonstrate how we can mitigate information leakage vulnerabilities by accurately modeling analog side-channels. I will discuss our approach in designing an open-source microarchitectural simulator which can accurately simulate analog side-channel signals (electromagnetic and power side-channels) in a variety of low-end processors. I will conclude my talk by describing future directions toward secure\, private\, and remote computing systems. \nBio: \nNader Sehatbakhsh is a Ph.D. Candidate in the School of Computer Science\, Georgia Institute of Technology. His research interest is on the broad area of Security and Privacy and Computer Architecture with emphasis on hardware security\, side-channels\, hardware-support for security and privacy\, and embedded system security. His work has been published in top venues such as MICRO\, ISCA\, and HPCA\, and has been recognized with several awards and honors including the MICRO-49 Best Paper Award and Micro Top-Picks Honorable Mention.

SUMMARY:Electrical and Computer Engineering Seminar: Hoda Naghibijouybari
DESCRIPTION:Abstract:\nGraphics Processing Units (GPUs) are integral components to most modern computing devices\, used to optimize the performance of today’s graphics and multi-media heavy workloads. They are also increasingly integrated on heterogeneous computing servers to accelerate a broad range of applications. Meanwhile\, recent trends in security show attacks on modern systems that originate in hardware and are exploitable by software. Given the growing use of GPUs in safety-critical applications\, understanding their security properties will become a first-class design objective. \nIn this talk\, I will present my research on covert and side channel attacks and defenses in modern GPUs. I show that it is possible to construct high bandwidth covert channels\, superior in bandwidth and quality to those on CPUs. Furthermore\, I demonstrate several variants of practical side channel attacks targeting both graphics and computational workloads. The talk will also present architectural mitigations to prevent the discovered attacks. Finally\, I will conclude the talk by my planned research at the intersection of emerging architectures and security. \nBio:\nHoda Naghibijouybari is currently a Ph.D. student at the Department of Computer Science and Engineering at the University of California\, Riverside. Her research interests include architectural support for security\, GPU security\, computer architecture and heterogeneous computing. Her research has resulted in the discovery of new attacks that have been disclosed to AMD\, and Nvidia companies\, and received coverage from technical news outlets. Her paper on GPU Side Channels was one of 11 papers selected for Top Picks in Hardware and Embedded Security\, 2019 (identifying best papers in those areas in 2013-2018
