[HTML][HTML] Chosen-ciphertext secure multi-hop identity-based conditional proxy re-encryption with constant-size ciphertexts
Abstract Proxy Re-Encryption (PRE) allows one user to delegate the decryption rights of
his/her ciphertexts to another user. Since the introduction of Multi-Hop Identity-Based PRE …

Identity-based proxy re-encryption schemes with multiuse, unidirection, and CCA security
A proxy re-encryption (PRE) scheme allows a proxy to transform a ciphertext under Alice's
public key into a ciphertext under Bob's public key on the same message. In 2006, Green …

Identity-based proxy re-encryption without random oracles
CK Chu, WG Tzeng - International Conference on Information Security, 2007 - Springer
A proxy re-encryption scheme allows Alice to temporarily delegate the decryption rights to
Bob via a proxy. Alice gives the proxy a re-encryption key so that the proxy can convert a …

Multi-use and unidirectional identity-based proxy re-encryption schemes
In a proxy re-encryption scheme, a semi-trusted proxy is given special power that allows it to
transform a ciphertext for Alice into a ciphertext for Bob without learning any information …

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 …

New identity-based proxy re-encryption schemes to prevent collusion attacks
L Wang, L Wang, M Mambo, E Okamoto - Pairing-Based Cryptography …, 2010 - Springer
In this paper, we propose two new constructions of identity-based proxy re-encryption (IB-
PRE). The most important feature of our schemes is that we no longer need the semi-trust …

Identity-based conditional proxy re-encryption with fine grain policy
An identity-based conditional proxy re-encryption scheme (IB-CPRE) allows a semi-trusted
proxy to convert a ciphertext satisfying one condition, which is set by the delegator, under …

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
