Traditional approaches to access control require one or more points of trust – a hardware security module or a centralized server managed by a data custodian. NuCypher provides a departure from this trust-dependent paradigm and introduces threshold split-key proxy re-encryption scheme (Umbral) – a combination of proxy re-encryption and decentralization – which enables performant permission management while preserving the encrypted state of the underlying data. Proxy re-encryption nodes provide re-encryption services without ever decrypting data. Cryptographic permissions are enforced through the issuance or revocation of re-encryption keys by data owners.
