0507 - Field-level encryption and multi-stakeholder decryption controls (threshold sharing)
Summary: Information elements and certification elements in records may be selectively encrypted using public key encryption so that only authorized trusted parties can decrypt. Decryption capability can be distributed among multiple parties using threshold schemes such as Shamir secret sharing, enabling jurisdictional or stakeholder-specific access controls. Different fields may be encrypted under different public keys, and replicated fields can be encrypted under multiple keys to support multiple authorized decryptors.
