SUMMARY:"Protocol-fuzzing mobile networks with open-source tools to enhance the security of LTE and 5G mobile networks"
DESCRIPTION:Title: “Protocol-fuzzing mobile networks with open-source tools to enhance the security of LTE and 5G mobile networks”\nSpeaker: Roger Piqueras Jover\, Security Researcher at Bloomberg LP \nDate and Time: Tuesday\, May 15 at 10:00 a.m. \nLocation: Donald Bren Hall 3011 \nAbstract:  \nThe Long Term Evolution (LTE) is the latest mobile communications standard being deployed globally to provide connectivity to billions of mobile devices\, from personal cell-phones to all types of critical systems\, such as self-driving cars\, medical appliances and industrial IoT sensors. As such\, the security of this communication standard is of paramount importance. However\, there is concerning inherent protocol security threats in LTE due to the large amount of unauthenticated and unprotected messages exchanged between a base station and a mobile device prior to the authentication security handshake. \nOpen source implementations of the LTE standards rapidly matured within the last couple of years. This\, in combination with sophisticated yet low cost software radio hardware\, fueled a new wave of security research that identified numerous protocol security issues in LTE that could allow an adversary to deny the service of mobile endpoints and track the location of users. This talk will summarize an ongoing effort on protocol-fuzzing LTE mobile networks using open-software tools. The protocol exploits against mobile endpoints that were discovered two years ago will be discussed as an introduction to the new systematic approach to protocol-fuzz LTE networks\, introducing as well a series of new potential exploits in the uplink\, against the network infrastructure and mobile devices outside of the radio range of the adversary. \nFinally\, these LTE protocol exploits are analyzed in the context of the recently (December 2017) published first release of the 3GPP 5G specifications (3GPP Rel. 15) for the 5G Radio Access Network (5G New Radio) and Core Network (5G System). Unfortunately\, not only most protocol-aware radio jamming issues and LTE protocol exploits are still a potential threat\, but there is a large number of new pre-authentication messages and new fields to already existing messages that could open the doors to further 5G-specific exploits. \nBiography: \nRoger Piqueras Jover is a Wireless Security Research Scientist and Security Architect at the CTO Security Architecture team of Bloomberg LP\, where he leads projects on mobile/wireless security and is actively involved in hardware security\, network security\, machine learning and anomaly/fraud detection. Previous to Bloomberg\, he spent 5 years at the AT&T Security Research Center (AT&T SRC)\, where he led the research area on wireless and LTE mobile network security and received numerous awards for his work. \nRoger holds 17 issued patents on mobile and wireless security\, has co-authored manuscripts in numerous top communications and security conferences and is the Technical Co-Chair for the ongoing IEEE 5G Summit series. \nRoger holds a Dipl. Ing. from Politechnical University of Catalunya (Barcelona\, Spain)\, a Master’s in Electrical and Computer Engineering from University of California Irvine and a Master’s/MPhil and EBD (Everything But Dissertation) in Electrical Engineering from Columbia University. \nFor a much more detailed biography\, details on his wireless security work on LTE\, 5G\, LoRaWAN and other technologies\, one can refer to http://rogerpiquerasjover.net/

SUMMARY:“Self-aware Computing: Combining Learning and Control to Manage Complex\, Dynamic Systems”
DESCRIPTION:<stThese self-aware systems are distinguished by awareness of user goals and operating environment; they continuously monitor themselves and adapt their behavior and foundational models to ensure the goals are met despite the challenges of complexity (diverse hardware resources to be managed) and dynamics (unpredictable changes in input workload or resource availability). In this talk\, I will describe how to build self-aware systems through a combination of control theoretic and machine learning techniques. I will then show how this combination enables new capabilities\, like increasing system robustness\, reducing application energy\, and meeting latency requirements even with no prior knowledge of the application. Finally\, these LTE protocol exploits are analyzed in the context of the recently (December 2017) published first release of the 3GPP 5G specifications (3GPP Rel. 15) for the 5G Radio Access Network (5G New Radio) and Core Network (5G System). Unfortunately\, not only most protocol-aware radio jamming issues and LTE protocol exploits are still a potential threat\, but there is a large number of new pre-authentication messages and new fields to already existing messages that could open the doors to further 5G-specific exploits. \nBiography: \nHenry Hoffmann is an Associate Professor in the Department of Computer Science at the University of Chicago. He was granted early tenure in 2018. At Chicago he leads the Self-aware computing group (or SEEC project) and conducts research on adaptive techniques for power\, energy\, accuracy\, and performance management in computing systems. He received the DOE Early Career Award in 2015. He has spent the last 17 years working on multicore architectures and system software in both academia and industry. He completed a PhD in Electrical Engineering and Computer Science at MIT where his research on self-aware computing was named one of the ten “World Changing Ideas”  by Scientific American in December 2011. He received his SM degree in Electrical Engineering and Computer Science from MIT in 2003. As a Masters student he worked on MIT’s Raw processor\, one of the first multicores. Along with other members of the Raw team\, he spent several years at Tilera Corporation\, a startup which commercialized the Raw architecture and created one of the first manycores (Tilera was sold for $130M in 2014). His implementation of the BDTI Communications Benchmark (OFDM) on Tilera’s 64- core TILE64 processor still has the highest certified performance of any programmable processor. In 1999\, he received his BS in Mathematical Sciences with highest honors and highest distinction from UNC Chapel Hill. \n

SUMMARY:"One does not need a Village to make a Billion Gate ASIC\, only a family if Synchoros VLSI Design Style is adopted"
DESCRIPTION:Name: Ahmed Hemani\nDate and Time: June 6\, 2018 at 4:00 p.m. \nLocation: Engineering Hall 2430 \nCommittee: Nikil Dutt (Host) \nAbstract: \nNorman Jouppi while introducing the record long list of authors of Google’s TPU paper at ISCA 2017 remarked – one needs a village to make a chip. This talk proposes a VLSI design method that holds promise of getting the same work done with just a family. This new VLSI design method is based on two principles\, one is to raise the abstraction of physical design to micro-architecture level from the present day boolean level standard cells and the second is to adopt a synchoros VLSI design style that enables composition by abutment to eliminate logic and physical synthesis for the end user. \nThe proposed method raises the abstraction of physical design to micro-architecture level by adopting coarse grain reconfigurable logic for computation\, storage and interconnect. All variations in function\, capacity\, architecture and degree of parallelism are realised by clustering and configuration of the coarse grain reconfigurable cells that we call as SiLago blocks – Silicon Lego Blocks. The micro-architecture level SiLago blocks replace boolean level standard cells as the atomic building blocks of the VLSI systems. These CGRA fabrics are domain specific – inner modem\, outer modem\, scratchpad memory\, dynamic programming\, NOCs\, infrastructural elements like RISC system controller\, PLL/CGU\, RGU\, DRAM control etc. Each CGRA fabric is holistically customized for its domain\, not just for computation but also for control\, interconnect\, address generation\, local storage etc. \nThe CGRAs provide an architecturally regular basis for a synchoros VLSI design style. Synchoricity is derived from the Greek word “choros” for space. The way synchronous systems divide time uniformly with clock ticks and enables temporal composition\, synchoros systems divide space uniformly with grids and enables spatial composition. All SiLago blocks are synchoros or ratiochoros and bring out all their interconnects to periphery on grid at right place and on right metal layer to enable composition by abutment of valid neighbours. \nThe net result of adopting the above two principles is that as soon as a design is refined down to micro-architecture level\, the dimension and position of every single wire segment and transistor is known with certainty in the 100 million gate design. Unlike standard cells\, where the position of standard cells and wires connecting them is left to physical synthesis\, in synchoros design style these aspects are parametrically hardened. Global wires like power grid\, clocks\, resets\, NOCs are not synthesised\, they emerge as a result of the abutment process. This enables automation of system models down to GDSII to create custom\, spatially distributed functional hardware\, i.e.\, ASICs with just a family. \nA proof of concept synthesis flow exists for transforming applications\, hierarchy of algorithms\, to GDSII and a path for system level to GDSII is well defined and is being implemented. System-level implies interacting applications. \nBiography: \nAhmed Hemani is Professor in Electronic Systems Design at School of ICT\, KTH\, Kista\, Sweden. His current areas of research interests are massively parallel architectures and design methods and their applications to scientific computing and autonomous embedded systems inspired by brain. In past he has contributed to high-level synthesis – his doctoral thesis was the basis for the first high-level\nsynthesis product introduced by Cadence called visual architect. He has also pioneered the Networks-on-chip concept and has contributed to clocking and low power architectures and design methods. He has extensively worked in industry including National Semiconductors\, ABB\, Ericsson\, Philips Semiconductors\, Newlogic. He has also been part of three start-ups.

SUMMARY:"Are there any questions?"
DESCRIPTION:Name: Yale Patt\nDate and Time: Thursday\, June 7 at 2:00 p.m. – 3:00 p.m. \nLocation: Engineering Hall 2430 \nAbstract:  \nToo many seminars can be characterized as 50 minutes of lecture\, followed by 5 minutes of questions. …and the first question makes it clear that nothing the speaker said in the 50 minutes was at all interesting to the audience. So\, we will take the opposite approach: 5 minutes of lecture\, followed by 50 minutes of questions. 5 minutes of lecture just to set the tone. Where the questions will take us is anybody’s guess. It will probably have something to do with computer architecture\, historical or current\, but it may venture off into something political …or at least politically correct. \nBiography: \nYale Patt is a Professor of Electrical and Computer Engineering and the Ernest\nCockrell\, Jr. Centennial Chair in Engineering at The University of Texas at Austin. He divides his\ntime between teaching the freshman and senior courses and his advanced graduate course in\nmicroarchitecture\, working with his PhD students\, and consulting in the microprocessor industry.\nHe earned obligatory degrees from reputable universities and has received more than his share of\nawards for his research and teaching. Patt has spent much of his career pursuring aggressive ILP\,\nout-of-order\, and speculative computer architectures\, such as HPSm. He has a Fellow of both the\nIEEE and ACM\, and a member of the National Academy of Engineering. He received his master’s\nand Ph.D. degrees in Electrical Engineering from Stanford University.
