In proxy re-encryption schemes, a semi-trusted entity called a proxy can convert a ciphertext
encrypted for Alice into a new ciphertext for Bob without seeing the underlying plaintext …

Abstract Proxy Re-Encryption (PRE) allows one user to delegate the decryption rights of
his/her ciphertexts to another user. Since the introduction of Multi-Hop Identity-Based PRE …

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 the fog computing architecture, a fog is a node closer to clients and responsible for
responding to users' requests as well as forwarding messages to clouds. In some medical …

In an identity-based proxy re-encryption (IB-PRE) scheme, a semi-trusted proxy can convert
a ciphertext under Alice's identity into a ciphertext for Bob. The proxy does not know the …

Identity-based proxy re-encryption schemes have been proposed to shift the burden of
managing numerous files from the owner to a proxy server. Nevertheless, the existing …

Proxy re-encryption allows a semi-trusted proxy with a re-encryption key to convert a
delegator's ciphertext into a delegatee's ciphertext, and the semi-trusted proxy cannot learn …

In proxy re-encryption (PRE), a semi-trusted proxy can convert a ciphertext originally
intended for Alice into one which can be decrypted by Bob, while the proxy cannot know the …

Outsource local data to remote cloud has become prevalence for Internet users to date.
While being unable to “handle”(outsourced) data at hand, Internet users may concern about …

In general, ID-based proxy re-encryption has the form of transferring data in a 1: 1 manner
between a data owner and data requestor. Therefore, only the data owner has the authority …
