CageCoach: Sharing-Oriented Redaction-Capable Distributed Cryptographic File System
Jason Carpenter, Zhi-Li Zhang
The modern data economy is built on sharing data. However, sharing data can be an expensive and risky endeavour. Existing sharing systems like Distributed File Systems provide full…
SoK: Rowhammer on Commodity Operating Systems
Zhi Zhang, Decheng Chen, Jiahao Qi +8
Rowhammer has drawn much attention from both academia and industry in the past years as rowhammer exploitation poses severe consequences to system security. Since the first compreh…
DRAMDig: A Knowledge-assisted Tool to Uncover DRAM Address Mapping
Minghua Wang, Zhi Zhang, Yueqiang Cheng +1
As recently emerged rowhammer exploits require undocumented DRAM address mapping, we propose a generic knowledge-assisted tool, DRAMDig, which takes domain knowledge into considera…
GhostKnight: Breaching Data Integrity via Speculative Execution
Zhi Zhang, Yueqiang Cheng, Surya Nepal
Existing speculative execution attacks are limited to breaching confidentiality of data beyond privilege boundary, the so-called spectre-type attacks. All of them utilize the chang…
TeleHammer: A Formal Model of Implicit Rowhammer
Zhi Zhang, Yueqiang Cheng, Dongxi Liu +2
The rowhammer bug allows an attacker to gain privilege escalation or steal private data. A key requirement of all existing rowhammer attacks is that an attacker must have access to…
