Title: Symmetric-key Cryptography for Memory Encryption

Speaker: Kazuhiko Minematsu (NEC and Yokohama National University)

Date: October 23, 2024
Abstract: Recent threats on computer memory increase the need for memory protection against eavesdropping or tampering, requiring the use of symmetric-key cryptography community for low-latency encryption. This talk discusses research directions and technological advancements of low-latency encryption and its application to memory encryption.

Biography: Kazuhiko Minematsu received his B.E., M.E. and Dr.S. degrees at Waseda University, Japan, in 1996, 1998, and 2008. He joined NEC and now works as a Research Fellow working on the design and analysis of symmetric-key cryptography and its application systems. He is also a visiting professor at Yokohama National University from 2019.


Title: A Systems Approach to Hardware Trojans

Speaker: Angelos D. Keromytis

Date: October 24, 2024
Abstract: Hardware trojans (HTs) represent one of the most challenging threat models in computer security. Due to the complexity and distributed nature of today’s electronics supply chains, there has been significant interest in developing scalable and accurate techniques for identifying such embedded malicious logic, at least in critical systems. However, much of the research in such techniques focuses on small target circuits with impractical HT usage (i.e., attack) scenarios, leading to both to questionable defenses and potential blind spots. In particular, most scenarios ascribe perfect knowledge and embedding control to the HT owner, consider simple (verging on simplistic) trigger and payload mechanisms, and cast the HT-attacker-defender interaction as a single shot game. In this talk, I will discuss a new model for hardware trojans that targets realistic circuits (i.e., full-blown CPUs) in the context of imperfect knowledge/control by the attacker and an adaptive defender within a repeated game, and explore certain implications and technical challenges.
