Random and Safe Cache Architecture to Defeat Cache Timing Attacks
Guangyuan Hu, Ruby B. Lee
Caches have been exploited to leak secret information due to the different times they take to handle memory accesses. Cache timing attacks include non-speculative cache side and co…
Protecting Cache States Against Both Speculative Execution Attacks and Side-channel Attacks
Guangyuan Hu, Ruby B. Lee
Hardware caches are essential performance optimization features in modern processors to reduce the effective memory access time. Unfortunately, they are also the prime targets for…
SoK: Hardware Defenses Against Speculative Execution Attacks
Guangyuan Hu, Zecheng He, Ruby Lee
Speculative execution attacks leverage the speculative and out-of-order execution features in modern computer processors to access secret data or execute code that should not be ex…
CloudShield: Real-time Anomaly Detection in the Cloud
Zecheng He, Ruby B. Lee
In cloud computing, it is desirable if suspicious activities can be detected by automatic anomaly detection systems. Although anomaly detection has been investigated in the past, i…
Smartphone Impostor Detection with Behavioral Data Privacy and Minimalist Hardware Support
Guangyuan Hu, Zecheng He, Ruby B. Lee
Impostors are attackers who take over a smartphone and gain access to the legitimate user's confidential and private information. This paper proposes a defense-in-depth mechanism t…
New Models for Understanding and Reasoning about Speculative Execution Attacks
Zecheng He, Guangyuan Hu, Ruby Lee
Spectre and Meltdown attacks and their variants exploit hardware performance optimization features to cause security breaches. Secret information is accessed and leaked through cov…
Smartphone Impostor Detection with Built-in Sensors and Deep Learning
Guangyuan Hu, Zecheng He, Ruby Lee
In this paper, we show that sensor-based impostor detection with deep learning can achieve excellent impostor detection accuracy at lower hardware cost compared to past work on sen…
