– If a client loses its per‑object keys, data becomes unrecoverable. Solutions involve threshold secret sharing of the client key across trusted devices, or re‑keying protocols that rotate keys without re‑uploading data.
| Mechanism | How It Works | Benefit | |-----------|--------------|---------| | | Keys never leave the user device; they can be stored in hardware security modules (HSMs) or secure enclaves. | Eliminates insider threats at the storage provider. | | Threshold Signature Schemes | A collective signature is generated only when a threshold of nodes collaborate. | Prevents rogue nodes from forging writes or deletes. | | Secure Multi‑Party Computation (SMPC) | Enables joint computation (e.g., aggregation) on encrypted fragments without exposing raw data. | Extends FSDSS‑513 to analytics while preserving privacy. | | Dynamic Node Admission | New nodes undergo attestation (TPM‑based) and are added only after a consensus vote. | Guarantees that only trusted hardware participates. | FSDSS-513
