In proxy re-encryption, a proxy can transform a ciphertext computed under A's public key into
one that can be opened under B's decryption key. In this paper, we focus on the the research …

In a proxy re-encryption scheme a semi-trusted proxy converts a ciphertext for Alice into a
ciphertext for Bob without seeing the underlying plaintext. A number of solutions have been …

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 …

Proxy re-encryption, as a cryptographic primitive, allows an untrusted proxy to transform a
ciphertext encrypted with the data owner's public key to a ciphertext encrypted with the …

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 …

Although a few unidirectional single-hop Identity-Based Proxy Re-Encryption (IBPRE)
systems are available in the literature, none of them is CCA secure in the standard model …

A proxy re-encryption (PRE) scheme involves three parties: Alice, Bob, and a proxy. PRE
allows the proxy to translate a ciphertext encrypted under Alice's public key into one that can …

In an identity-based proxy re-encryption (IB-PRE) scheme, a semi-trusted proxy can convert
a ciphertext under Alice's identity into a ciphertext for Bob. The proxy does not know the …

In 1998, Blaze, Bleumer, and Strauss proposed a kind of cryptographic primitive called proxy
re-encryption. In proxy re-encryption, a proxy can transform a ciphertext computed under …

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 …
