A Timed-Release Proxy Re-Encryption Scheme [PDF]
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2011 Timed-Release Encryption (TRE) is a kind of time-dependent encryption, where the time of decryption can be controlled. More precisely, TRE prevents even a legitimate recipient decrypting a ciphertext before a semi-trusted Time Server (TS) sends trapdoor sT assigned with a release time T of the encryptor's choice.

Proxy re‐encryption via indistinguishability obfuscation
Security and Communication Networks, 2016 AbstractIn this paper, we present a proxy re‐encryption (PRE) scheme via an indistinguishability obfuscation () by adding two algorithms to the public key encryption scheme by Sahai and Waters' (STOC 2014). Although a re‐encryption function from one public key to another can be considered as a randomized functionality on the underlying plaintext and ...
