Proxy re-encryption

ID: proxy-re-encryption

Proxy re-encryption is a technique in the field of cryptography that allows a third-party entity, known as a proxy, to transform a ciphertext (an encrypted message) that was encrypted under one public key into a ciphertext that can be decrypted with another public key, without having access to the underlying plaintext or the private keys. The core idea behind proxy re-encryption is to enable secure delegation of decryption rights.
