THU Hardware Architecture Security

Welcome to THU HAS Lab. Our research advances efficient, secure computing from processor microarchitectures to chips, chiplets, and interconnects.

Research Focus 1

Endogenous Efficiency and Security in Computing Microarchitectures

  • By systematically exploring performance design spaces and attack surfaces from prefetchers to memory-access units, we proposed the first timer-free generic cache-attack primitive. This research earned public acknowledgment from SiFive and directly informed China's open-source XiangShan processor.
  • The related prefetcher-attack work received the Best Paper Award at AsianHOST 2025.
Research Focus 2

Efficiency and Security in Novel Computing Chips and Chiplets

  • We constructed a high-precision reverse-engineering and attack framework for cross-chiplet secure domains.
  • We performed the first systematic evaluation exposing the fragility of weight-obfuscation defenses in Computing-in-Memory chips, demonstrating a key-parsing success rate exceeding 90%. This was the Department of Electronic Engineering's first lead-institution paper at a top information-security conference.
Research Focus 3

Efficient and Secure Computing Interconnects

  • We systematically characterized and quantified performance interference in CXL memory, restoring main-memory bandwidth to 99%.
  • We designed a CXL-secure key-value-store framework for multi-host sharing, delivering 3.45 times the throughput of advanced Redis implementations while preserving isolation across shared-memory resources.
