Technical Reports

2019 Shadowclone: Thwarting and Detecting DOP Attacks with Stack Layout Randomization and Canary

• Yunjie Pan, Shibo Chen, Cheng Chi, Yifan Guan
• In this project, we developed a compile-time randomization technique to thwart Data-Oriented Programming attacks. Furthermore, we utilize stack canary to detect ongoing attacks. Our results show that our approach has low performance overhead on programs with few function calls. We also show that it is practically hard for attackers to succeed even under our conservative assumptions.

Deep Dive Into the Cost of Context Switch

• Shibo Chen, Yu Wu, Xinyun Jiang, Wen-Jye Hu
• In this project, we identified the major components of the context swtich overhead on modern CPUs. We show that data cache misses and d-TLB misses are two major contributors of the overhead. Furthermore, we demonstrate that it requires a non-trivial effort to implement an user-level multithreading library.

2018 ThundaTag: Disparate Domain Tagging to Enforce Benign Program Behavior

• Alex Kisil, Shibo Chen
• In this project, we implemented and evaluated the architectural support for domain tagging. Our study shows that such design only requires negligible area overhead and induces low performance overhead.

2018 An Alpha-64 Out-of-Order Processor Design

• Shibo Chen, Zhen Feng, Chin-Wei Hsu, Yueying Li, Wenhao Peng
• Our team implemented a three-way superscalar alpha-64 out-of-order CPU. We are able to achieve 100MHz and IPC of 0.94 with Synopsys 90nm generic library for education under the constraint area requirements.

2018 Understanding the Value of Ensemble of Moving Target Defenses in Morpheus

• Shibo Chen
• In this work, we studied the average time needed to penetrate a de-featured Morpheus design. The result underscores the robustness of Morpheus defenses.

2018 PowerSpy Upgraded: Location Tracking using Mobile Device Power Analysis

• Shibo Chen, Shengtuo Hu
• In this work, we extended the original Powerspy paper to more environments. Our study shows the availability of attacker using this attack to conduct indoor tracking.
