Our paper “Secure the Stream, Not the Hosts: Attribute-Based Encryption for DRM-Enabled Video Streaming” has been accepted at ACM MMSys 2025.
The work proposes using attribute-based encryption (ABE) to secure video streams at the content level rather than the transport level, enabling fine-grained, policy-based access control for streaming video without requiring a trusted server at playback time.
