Time‐and ID‐based proxy reencryption scheme is proposed in this paper in which a type‐
based proxy reencryption enables the delegator to implement fine‐grained policies with one …

Proxy re-encryption is a cryptographic primitive developed to delegate the decryption right
from one party (the delegator) to another (the delegatee). In a proxy re-encryption scheme …

In a proxy re-encryption scheme, a semi-trusted proxy is given special power that allows it to
transform a ciphertext for Alice into a ciphertext for Bob without learning any information …

In a Idendity-based proxy re-encryption (IBPRE) scheme, a proxy, converts a ciphertext for
one identity into a ciphertext for another identity without knowing the underlying plaintext …

Proxy re-encryption is a cryptographic primitive developed to delegate the decryption right
from one party (the delegator) to another (the delegatee). So far, research efforts have only …

An identity-based proxy re-encryption scheme (IB-PRE) allows a semi-trusted proxy to
convert an encryption under one identity to another without revealing the underlying …

Abstract In 1998, Blaze, Bleumer, and Strauss proposed a kind of cryptographic primitive
called proxy re-encryption. In proxy re-encryption, a proxy can transform a ciphertext …

A proxy re-encryption scheme allows Alice to temporarily delegate the decryption rights to
Bob via a proxy. Alice gives the proxy a re-encryption key so that the proxy can convert a …

In a proxy re-encryption scheme, a semi-trusted proxy converts a ciphertext for Alice into a
ciphertext for Bob without seeing the underlying plaintext. A number of solutions have been …

In proxy re-encryption, a proxy can transform a ciphertext computed under A's public key into
one that can be opened under B's decryption key. In this paper, we focus on the the research …
