Key Agreement for Decentralized Secure Group Messaging with Strong Security Guarantees
Secure group messaging protocols, providing end-to-end encryption for group communication, need to handle mobile devices frequently being offline, group members being added or removed, and the possibility of device compromises during long-lived chat sessions. Existing work targets a centralized network model in which all messages are routed through a single server, which is trusted to provide a consistent total order on updates to the group state. In this paper we adapt secure group messaging for decentralized networks that have no central authority. Servers may still optionally be used, but they are trusted less. We define decentralized continuous group key agreement (DCGKA), a new cryptographic primitive encompassing the core of a decentralized secure group messaging protocol; we give a practical construction of a DCGKA protocol and prove its security; and we describe how to construct a full messaging protocol from DCGKA. In the face of device compromise our protocol achieves forward secrecy and post-compromise security. We evaluate the performance of a prototype implementation, and demonstrate that our protocol has practical efficiency.

Integrating Germ with AT Protocol — Germ Network
End-to-end encrypted Germ DM is now a Bluesky messenger. In this technical post, we introduce the architecture of Germ’s integration with AT Protocol. From the beginning, Germ has been building for an interoperable E2EE ecosystem, and this extends to our integration with AT Protocol. We’ll define th
OAuth for AT Protocol | Bluesky
We are very happy to release the initial specification of OAuth for AT Protocol! This is expected to be the primary authentication and authorization system between atproto client apps and PDS instances going forward, replacing the current flow using App Passwords and createSession over time.
