Non-Transferable Proxy Re-Encryption Scheme [PDF]

2012 5th International Conference on New Technologies, Mobility and Security (NTMS), 2012
A proxy re-encryption (PRE) scheme allows a proxy to re-encrypt a ciphertext for Alice (delegator) to a ciphertext for Bob (delegatee) without seeing the underlying plaintext. However, existing PRE schemes generally suffer from at least one of the followings.

Universal Proxy Re-Encryption

2021
We put forward the notion of universal proxy re-encryption (UPRE). A UPRE scheme enables a proxy to convert a ciphertext under a (delegator) public key of any existing public-key encryption (PKE) scheme into another ciphertext under a (delegatee) public key of any existing PKE scheme (possibly different from the delegator one).

Proxy Re-encryption with Keyword Search from Anonymous Conditional Proxy Re-encryption

2011 Seventh International Conference on Computational Intelligence and Security, 2011
Proxy re-encryption (PRE) allows a proxy to transform a cipher text for Alice (delegator) to be the one which can be decrypted by Bob (delegatee). Since it is introduced by Blaze et al. in 1998, many variants of PRE have been proposed. In this paper, we concentrate on two of them: anonymous conditional proxy re-encryption (ACPRE) and constrained proxy ...
