Loom: Weaving PCS-Preserving and Searchable Cloud Backups for Secure Messaging
Summary: Loom is the first searchable encrypted backup system preserving post-compromise security, embedding data keys in its searchable index for efficient multi-keyword conjunctive retrieval (“searchable-implies-decryptable”). LoomRelay extends this to dynamic groups without redundant uploads, outperforming CKS by 25–87×. (summarized by gpt-5.6-luna on Jul 26 2026)
