Session: End-To-End Encrypted Conversations With Minimal Metadata Leakage
This addresses privacy concerns for users seeking secure communication with reduced metadata exposure, though it appears incremental as it builds on existing encryption and routing techniques.
The paper tackles the problem of secure messaging with minimal metadata leakage by introducing Session, an open-source application that uses decentralized storage and onion routing to send end-to-end encrypted messages while maintaining features like multi-device syncing and voice/video calling.
Session is an open-source, public-key-based secure messaging application which uses a set of decentralised storage servers and an onion routing protocol to send end-to-end encrypted messages with minimal exposure of user metadata. It does this while providing the common features expected of mainstream messaging applications, such as multi-device syncing, offline inboxes, and voice/video calling.
