Attribute-based proxy re-encryption scheme with multiple features
Tongxin xuebao, 2019 A ideal proxy re-encryption scheme has five features,such as one-way encryption,non-interaction,repeatability,controllability and verifiability.The existing schemes,however,have only two or three of the five features,which reduces the utility of them to ...

Proxy Re-Encryption Scheme for Decentralized Storage Networks
Applied Sciences, 2022 Storage is a promising application for permission-less blockchains. Before blockchain, cloud storage was hosted by a trusted service provider. The centralized system controls the permission of the data access. In web3, users own their data.

IEEE Access, 2017 An outsourcing re-encryption program can help a ciphertext owner (delegator) transform his/her ciphertext into another ciphertext of delegatee. For example, an e-mail receiver can re-transfer an encrypted e-mail to his secretary while allowing the e-mail

Proxy Re-encryption from Lattices [PDF]
, 2014 We propose a new unidirectional proxy re-encryption scheme based on the hardness of the LWE problem. Our construction is collusionsafe and does not require any trusted authority for the re-encryption key generation. We extend a recent trapdoor definition for a lattice of Micciancio and Peikert. Our proxy re-encryption scheme is provably CCA-1 secure in

Efficient Unidirectional Proxy Re-Encryption
, 2010 Proxy re-encryption (PRE) allows a semi-trusted proxy to convert a ciphertext originally intended for Alice into one encrypting the same plaintext for Bob. The proxy only needs a re-encryption key given by Alice, and cannot learn anything about the plaintext encrypted.

An Enhanced Approach for CP-ABE with Proxy Re-encryption in IoT Paradigm
Jordanian Journal of Computers and Information Technology, 2022 In Internet of Things (IoT), encryption is a technique in which plaintext is converted to ciphertext to make it non-recovered by the attacker without secret key.

Conditional Proxy Broadcast Re-Encryption
, 2009 A proxy re-encryption (PRE) scheme supports the delegation of decryption rights via a proxy, who makes the ciphertexts decryptable by the delegatee. PRE is useful in various applications such as encrypted email forwarding. In this paper, we introduce a more generalized notion of conditional proxy broadcast re-encryption (CPBRE).
