Guest seminar 12:00 AM Security Implications of Emerging Architectural Paradigms on Machine-Learning Hardware Ilia Polian, University of Stuttgart Dedicated hardware blocks for machine learning (ML) are receiving an enormous attention these days. They can decisively improve the performance of ML systems; enable ML in resource-constrained applications; and avoid the undesired outsourcing of ML tasks to third-party services. Emerging architectural paradigms, such as memristive, in-memory, approximate or stochastic computing, have been found to deliver further improvements; indeed, ML hardware is considered by many to be the primary application for such paradigms. This talk will explore the consequences of novel architectures for security of ML hardware. An already non-obvious question is how to define security in the first place: What assets or secrets might be under attack in a system that lacks secret keys or other cryptographic functions? It turns out that two communities, ML and hardware-oriented security, have their own notions of security; these notions come together and interact in non-trivial ways. Incorporating emerging architectures into the security considerations adds another layer of complexity. Of particular interest is whether emerging architectural paradigms can contribute to counteracting security threats, e.g., by better exploiting randomization. This gives rise to a design space where security can be traded for the complexity of ML models; for the size of basic ML hardware components; and for the accuracy achieved by ML algorithms. Bio: Ilia Polian is a Full Professor and the Director of the Institute for Computer Architecture and Computer Engineering at the University of Stuttgart, Germany. He received his Diplom (MSc) and PhD degrees from the University of Freiburg, Germany, in 1999 and 2003, respectively. Prof. Polian co-authored over 250 scientific publications and received two Best Paper Awards. He is a Senior Mem­ber of IEEE. Prof. Polian is the Speaker of DFG’s Priority Program 2253 “Nano Security”, a Director of the Graduate School “Intelligent Methods for Test and Reliability” in Stuttgart (funded by Advantest) and of the Center for Integrated Quantum Science and Technology (IQST). His scientific interests include hardware-oriented security, emerging architectures, test methods, and quantum computing. 13:00 Guest seminar 2
