Ledger Key Ring Protocol
summary
Ledger uses the device plus the 24‑word seed to deterministically generate hundreds of encryption keys, introduces deterministic encryption keys, supports group keys for folders and selective sharing, and enforces revocation by re‑encrypting resources with rotated keys. Ledger Live already uses the protocol to sync local settings across desktop and mobile by storing only ciphertext on servers while sharing keys between devices, enabling end‑to‑end encrypted messaging and private photo sharing without Ledger having access to user data.
