# SCASE
This repository contains the implementation of the Athena framework discussed in the *upcoming* research paper ["SCASE: Automated Secret Recovery via Side-Channel-Assisted Symbolic Execution" (USENIX 2025)](https://d-we.me/papers/scase_usenix25.pdf).

The framework automates the recovery of secrets from a given side-channel memory trace.

## Supported Platforms
The main component of Athena, i.e., its recovery engine, requires no specific platform.
However, the SGX tracing component is build on top of [SGX-Step](https://github.com/jovanbulck/sgx-step) and targets Intel SGX enclaves, thus requiring a CPU compatible with SGX and system compatible with SGX-Step, e.g., Ubuntu 22.04.
The code was developed and tested on Ubuntu 22.04 and Arch Linux.

## Dependencies
Most dependencies can be installed by simply running `cd athena; pip3 install -r requirements.txt`.
Furthermore, one needs to install the following (Ubuntu) packages:
```
apt install build-essential libelf-dev 
```
For the SGX tracing component, one needs to install [SGX-Step](https://github.com/jovanbulck/sgx-step) according to the installation instructions in its repo.
