DESCRIPTION:Microarchitectural side-channel attacks exploit subtle hardware
  behaviors\, such as cache activity and instruction retirement patterns\, 
 to extract sensitive information. Understanding these attacks is essential
  for developing effective mitigations. However\, real hardware imposes lim
 itations on observability and experimental flexibility. The gem5 simulator
 \, an open-source and highly extensible architectural simulator\, provides
  a powerful environment for analyzing these attacks with fine-grained cont
 rol over execution\, memory access\, and timing behaviors.\n\n\nIn this pr
 esentation\, I will demonstrate how gem5 can be used to evaluate side-chan
 nel vulnerabilities\, focusing on attack scenarios such as Flush+Fault and
  Access-Retired attacks targeting the RISC-V architecture. By simulating b
 oth attack and non-attack conditions under controlled settings\, gem5 enab
 les precise identification of attack patterns. These datasets can then be 
 used to train machine learning (ML) models for classifying microarchitectu
 ral events with high accuracy.\n\n\nBy leveraging gem5’s multi-ISA suppo
 rt\, full-system simulation\, and cycle-accurate modeling\, researchers ga
 in deeper insights into attack mechanisms\, accelerate the prototyping of 
 detection techniques\, and design architectures resilient to both known an
 d emerging side-channel threats. This approach not only enhances detection
  capabilities but also informs secure hardware-software co-design strategi
 es.
