The TI Messenger: Advancing Secure Healthcare Communication with Matrix
summary
A secure healthcare messenger built on the Matrix protocol with end-to-end double‑ratchet plus an access control layer using Germany’s telematic infrastructure smart‑card login and connector. Architecture combines a Matrix homeserver (often Synapse), a messenger proxy that gatekeeps federation, a registration service and a test reference suite for mandatory interoperability certification. One provider is approved in 2024, rollout to insured citizens begins 15 July 2025 adding roughly 74 million users, and scaling uses pooled interop tests and vendor audits.
