PyFEX: Uncovering Evasive Python-based Threats via Resilient and Exhaustive Path Exploration
Meng Wang, Yue Ma, Majid Garoosi +4
The rapid expansion of the Python ecosystem has fueled two distinct but converging threats: adversaries increasingly target the software supply chain via the Python Package Index (…
Anota: Identifying Business Logic Vulnerabilities via Annotation-Based Sanitization
Meng Wang, Philipp Görz, Joschua Schilling +4
Detecting business logic vulnerabilities is a critical challenge in software security. These flaws come from mistakes in an application's design or implementation and allow attacke…
EdgeMoE: Empowering Sparse Large Language Models on Mobile Devices
Rongjie Yi, Liwei Guo, Shiyun Wei +3
Large language models (LLMs) such as GPTs and Mixtral-8x7B have revolutionized machine intelligence due to their exceptional abilities in generic ML tasks. Transiting LLMs from dat…
STI: Turbocharge NLP Inference at the Edge via Elastic Pipelining
Liwei Guo, Wonkyo Choe, Felix Xiaozhu Lin
Natural Language Processing (NLP) inference is seeing increasing adoption by mobile applications, where on-device inference is desirable for crucially preserving user data privacy…
Protecting File Activities via Deception for ARM TrustZone
Liwei Guo, Kaiyang Zhao, Yiying Zhang +1
A TrustZone TEE often invokes an external filesystem. While filedata can be encrypted, the revealed file activities can leak secrets. To hide the file activities from the filesyste…
Minimum Viable Device Drivers for ARM TrustZone
Liwei Guo, Felix Xiaozhu Lin
While TrustZone can isolate IO hardware, it lacks drivers for modern IO devices. Rather than porting drivers, we propose a novel approach to deriving minimum viable drivers: develo…
Let the Cloud Watch Over Your IoT File Systems
Liwei Guo, Yiying Zhang, Felix Xiaozhu Lin
Smart devices produce security-sensitive data and keep them in on-device storage for persistence. The current storage stack on smart devices, however, offers weak security guarante…
Transkernel: Bridging Monolithic Kernels to Peripheral Cores
Liwei Guo, Shuang Zhai, Yi Qiao +1
Smart devices see a large number of ephemeral tasks driven by background activities. In order to execute such a task, the OS kernel wakes up the platform beforehand and puts it bac…
