We’re excited to showcase our latest contributions to the HDF5 ecosystem at SC25, the premier international conference for high-performance computing, networking, storage, and analysis. As active members of the HDF5 community, we’re driving innovation in data security while helping shape the future direction of this critical technology that powers scientific computing worldwide. Join us for our cutting-edge research presentations and collaborative discussions that will define the next generation of HDF5 capabilities.

Paper Presentation
“Securing HDF5 Plugins with Digital Signatures”

Sunday, November 16, 2025, 2:03pm – 2:22pm CST in 242

Join The HDF Group’s software engineer Glenn Song as she presents new work on enhancing HDF5 security through digital signature implementation for plugins. Plugins are valuable extensions that enhance the functionality of HDF5. They play a crucial role in adding custom features, such as various compression filters and VFDs, without requiring extensive changes to the source code. This work provides a novel approach to plugin authentication with real-world implementation strategies and a performance impact analysis
