Security and Privacy Heterogeneous Environment for Reproducible Experimentation

Homepage

CALL FOR REPRESENTATIVE EXPERIMENT ENVIRONMENTS (REEs)

Reproducibility is vital to scientific progress but remains a challenge in computer science, particularly in systems, networking, and cybersecurity/privacy research. By working together, we can improve the reusability and transparency of research artifacts, making it easier to build on prior work. The SPHERE research infrastructure aims to accelerate this progress by soliciting Representative Experimentation Environments (REEs) for integration into SPHERE. To support this effort, selected REE contributors will receive paid virtual internships to port their work to SPHERE, ensuring broader accessibility and long-term impact.
Application deadline: April 15, 2025

Merge Portal
Kubernetes-based frontend implementation delivers core API services for experiment compilation and realization, alongside XDC (Experiment Development Container) pods that enable secure user access through SSH/Jupyter interfaces and connect to backend facilities via VPN tunnels. This microservice architecture supports flexible integration and scalable testbed operations.
Merge Facilities
Distributed backend resources combine infrastructure services and podman-containerized core API components with Qemu/KVM virtualization for user experiments, leveraging Cumulus Linux switches for VXLAN-based network segmentation. The system maintains strictly separated networks for infrastructure control and experiment traffic, while supporting multi-facility integration through the Merge Facility API.
Machine learning nodes
Ten powerful GPU-equipped servers are crucial in developing cybersecurity systems incorporating real-time machine learning detection and response capabilities.
Embedded compute nodes
The embedded-compute infrastructure, featuring 400 diverse nodes with CPUs and GPUs, forms a robust backbone for exploring edge security paradigms and advancing federated learning protocols in secure environments.
General compute nodes
Empowering privacy-centric experimentation, the 200 general-compute nodes integrate specialized processor architectures like Intel TDX and AMD SEV, enabling researchers to conduct large-scale security measurements and trustworthy computing investigations.
Embedded CPS
Critical infrastructure protection research finds its home in the cyber-physical systems setup, where complete architectures emulate industrial control systems, allowing security researchers to test and validate defensive measures for vital facilities.
Software-defined networking nodes
