Proxy re-encryption is scheme that allows a proxy to re-encrypt a ciphertext, encrypted with the public key of a user A, into a ciphertext that can be decrypted with a private key of a user B, without having access to the private key of A or B, as well as to the plaintext.
Green and Ateniese describe an Identity-based proxy re-encryption scheme in their paper and prove its security. An implementation of their solution can be found in my github repository. This is a python implementation using the Charm Crypto tool
