BeeKEM: Decentralized, Secure and Efficient Group Key Agreement
Group key agreement protocols are essential for modern secure messaging. Most existing group key agreement protocols assume a centralized model with a semi-trusted service that mediates the communication. This is efficient, but problematic for some important applications, since a central service can be a choke point for surveillance and censorship. There is a nascent literature on decentralized group key agreement that avoids such reliance, but existing proposals either do not scale, with update costs linear or quadratic in the group size, or lack proofs of security. Centralized protocols can offer much lower (logarithmic) cost. We present BeeKEM, the first decentralized group key agreement protocol with logarithmic update cost in the common case (degrading to linear in the worst case) and proofs of security. We provide an open-source implementation and demonstrate that it is competitive with OpenMLS. BeeKEM opens the door for a range of communication and collaboration applications offering not only end-to-end encryption, but also metadata privacy and censorship resistance.
Investigation into Message Layer Security (MLS)
This article investigates Message Layer Security (MLS), the IETF standard protocol (RFC 9420) for Signal-style end-to-end encryption. Through a practical analysis of OpenMLS (the Rust reference implementation) and a demonstration CLI chat application (mls-chat), the post reveals the substantial gap between protocol specification and production deployment. Introduction MLS (Message Layer …

Decentralization Trade Offs in AT Protocol and ActivityPub DWeb Camp 2026
Christine Lemmer Webber is lead author and co-editor of the W3C ActivityPub specification. Daniel Holmgren is Head of Protocol at Bluesky, working on the AT Protocol specification at the IETF. Join us for a discussion on decentralization trade-offs and other design decisions in the two protocols, and what that means for different architectures, structures, and even future points of convergence. Moderated by Boris Mann
Room to grow: Building collaborative, open software
We examine one approach to collaborative, open software by building on Matrix, a secure, decentralised, real-time communication protocol with generic database capabilities hiding beneath its current focus on chat.
