Multi-use unidirectional identity-based proxy re-encryption from hierarchical identity-based encryption
At ACNS 2007, Ateniese and Green proposed the concept of ID-based proxy re-encryption
(IBPRE), where a semi-trusted proxy with some information (aka re-encryption key), can …

Efficient and fully CCA secure conditional proxy re-encryption from hierarchical identity-based encryption
A proxy re-encryption (PRE) allows a data owner to delegate the decryption rights of some
encrypted data stored on the cloud without revealing the data to an honest-but-curious cloud …

New constructions for identity-based unidirectional proxy re-encryption
We address the cryptographic topic of proxy re-encryption (PRE), which is a special public-
key cryptosystem. A PRE scheme allows a special entity, known as the proxy, to transform a …
