  • Encrypted Spaces is an architecture for collaborative applications ensuring encrypted data storage and cryptographically verifiable operations.
  • Addresses risks of centralized cloud collaboration tools, including exposure to unauthorized access, loss of user control over data policies, and self-censorship due to privacy concerns.
  • Built on five components: membership state, verifiable database with append-only changelog, key management, key retention system, and application-defined operations to manage encryption and access control.
  • Includes a prototype sync engine (similar to Firebase or Supabase) that uses encrypted spaces to handle verifiable data operations and synchronization across clients.
  • Developed by a research team with collaboration and support from Microsoft Research and Harvard's Berkman Klein Center, focusing on cryptography and privacy-preserving systems.
