Artifacts

Agora

Agora is a binary verification framework for confidential computing that makes verification more open, auditable, and trust-minimized. By combining validator-centric design with blockchain-based task management, it supports practical verification of security policies such as software fault isolation and side-channel mitigation.

Deflection

Deflection is an SGX shielding runtime (SGX middleware) that can run nearly unmodified C/C++ code securely. Other than Graphene-SGX, SCONE, Occlum, etc., it can protect the code secrecy and data confidentiality at the same time.

PoBF

Proof of Being Forgotten (PoBF) and PoBF-Compliant Framework (PoCF) prototypes.

Reusable Enclaves

This is a research project aims to solve the cold start problem without sacrificing the security by creating a method to securely reuse the enclave. The paper is accepted to 2023 USENIX Security Symposium.

Picachv

We advance the research in this area by introducing Picachv, a lightweight runtime security monitor that can be seamlessly integrated into existing query execution engines, plus verifiable formal guarantees written in Coq.
