2021 MITRE eCTF Challenge: Secure Common Embedded Wireless Link (SCEWL) by 0xDACC

This repository implements our team's design for MITRE's 2021 Embedded System CTF (eCTF). This code was designed with security in mind, preparing for the attack phase in which opposing teams will attempt to exploit our design.

Documentation

Make sure to check out the documentation. Our SCEWL Bus Controller code is documented in controller.h, including the structs used for various communications. Our SCEWL Security Server is documented in the sss readme. Our high-level Design Document is also available at Design Document.

Getting Started

Please see the Getting Started Guide.

Also see the distributed documentation for a guide to the design and features of this code.

Project Structure

The project code is structured as follows

• controller/ - Contains everything to build the SCEWL Bus Controller. See Controller README
• cpu/ - Contains everything to build the user code of the CPU. See CPU README
• dockerfiles/ - Contains all Dockerfiles to build system
• radio/ - Contains the Radio Waves Emulator
• socks/ - Directory to hold sockets for the network backend
• sss/ - Contains the Scewl Security Server and a deployment helper program. See SSS README
