SUMMARY:Securing HDF5 Plugins with Digital Signatures
DESCRIPTION:Glenn Song and Michael Breitenfeld (The HDF Group) and Suren B
 yna (Ohio State University)\n\nHDF5 is a popular data management and I/O l
 ibrary used by numerous scientific and industry applications. HDF5 in the 
 recent years pluggable extensions to enhance HDF5’s functionality to impro
 ve performance and to utilize underlying hardware and file systems. Plugin
 s play a crucial role in adding custom features, such as compression filte
 rs, virtual file drivers (VFDs), and virtual object layer (VOL) connectors
 , without requiring extensive changes to the source code or modifications 
 to the main library. While the plugin capability gives power to extend HDF
 5, plugins could be misused for malicious routing of HDF5 calls. To improv
 e the security of HDF5 systematically, in this study, we explore the optio
 n of digitally signing plugins. This would help ensure the authenticity an
 d integrity of any plugins that users may use. We discuss a few implementa
 tion scenarios in HDF5 and assess the accuracy and overhead associated wit
 h the plugin verification process.\n\nRecording: Livestreamed, Recorded\n\
