Cryptanalysis of a Certificateless Proxy Re-encryption Scheme
2013 Fourth International Conference on Emerging Intelligent Data and Web Technologies, 2013Recently, Sur et al. introduced a new primitive named certificateless proxy re-encryption, which enjoys the advantages of certificateless public key cryptography while providing the functionalities of proxy re-encryption. They further proposed a certificateless proxy re-encryption scheme, and claimed that their scheme is secure against chosen-cipher ...

Multi-key Homomorphic Proxy Re-Encryption
2018In 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).

Certificate-Based Conditional Proxy Re-Encryption
2014A 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
