Multi-key Homomorphic Proxy Re-Encryption

2018
In this paper, we propose a new notion of multi-key homomorphic proxy re-encryption (MH-PRE) in which inputs of homomorphic evaluation are encrypted by different public keys and the evaluated ciphertext is decrypted by a single secret key. We obtain it by adding the re-encryption property of proxy re-encryption to multi-key homomorphic encryption (MHE).

Certificateless Proxy Re-Encryption Without Pairings

2014
Proxy re-encryption (PRE) allows a proxy with re-encryption keys to transform a ciphertext under a given public key into a ciphertext of the same message under a different public key, and can not learn anything about the encrypted message. Due to its transformation property, PRE has many practical applications such as cloud storage, confidential email,

Factoring-Based Proxy Re-Encryption Schemes

2013
Proxy re-encryption (PRE) realizes delegation of decryption rights, enabling a proxy holding a re-encryption key to convert a ciphertext originally intended for Alice into an encryption of the same message for Bob, and cannot learn anything about the encrypted plaintext.

Proxy Re-encryption with Delegatable Verifiability

2016
Proxy re-encryption is a public key encryption technique that allows a proxy to perform re-encryption without exposing the corresponding plaintext. As a result, proxy re-encryption has increased utility, and can be used in a number of fields including cloud computing.

Certificate-Based Conditional Proxy Re-Encryption

2014
A proxy re-encryption scheme (PRE) allows a semi-trusted proxy to convert a ciphertext encrypted under one key into an encryption of the same plaintext under another key. In the process of the arithmetic processing, proxy should be able to learn as little information about the plaintext as possible. Conditional proxy re-encryption (CPRE) is a primitive

Anonymous ID-Based Proxy Re-Encryption

2012
ID-based proxy re-encryption (IBPRE) allows a proxy with some information (a.k.a. re-encryption key) to transform the ciphertext under one identity to another ciphertext under another identity. These two ciphertexts can yield the same plaintext, while the proxy cannot get any information of the plaintext.
