- This paper defines a new form of proxy re-encryption with some important new properties not exhibited by previous approaches, which enable general access policies to be embedded into a key. Secure proxy re-encryption is significant because it allows the management of encrypted data to be outsourced to the cloud without disclosing the data itself. Our proxy re-encryption scheme allows the encrypted data to be further converted for another group of data users with a new access policy, enabling secure data sharing.
It has been used in the blockchain application NuCypher (https://www.nucypher.com/) among others for decentralised distributed key management.
