Encrypted domain reversible data hiding based on proxy re-encryption in distributed environment
Journal of King Saud University: Computer and Information SciencesReversible data hiding in encrypted domain (RDH-ED) addresses data security and privacy protection issues. However, traditional RDH-ED algorithms face challenges in terms of dynamic authorization, multiparty collaboration, and secure sharing in ...

Multi-authority based CP-ABE proxy re-encryption scheme for cloud computing
网络与信息安全学报, 2022 Proxy re-encryption allows a proxy to convert a ciphertext related to a certain access policy into another one with a different access policy without uncovering the underlying plaintext, which makes the proxy re-encryption technology to be an important ...

Non-transferable Proxy Re-encryption [PDF]
The Computer Journal, 2018 The traditional security notion of proxy re-encryption (PRE) focuses on preventing the proxy learning anything about the encrypted messages. However, such a basic security requirement is clearly not enough for scenarios where the proxy can collude with Bob.

Key-Private Proxy Re-encryption [PDF]
, 2009 Proxy re-encryption (PRE) allows a proxy to convert a ciphertext encrypted under one key into an encryption of the same message under another key. The main idea is to place as little trust and reveal as little information to the proxy as necessary to allow it to perform its translations. At the very least, the proxy should not be able to learn the keys

A Proxy Re-Encryption Approach to Secure Data Sharing in the Internet of Things Based on Blockchain
IEEE Systems Journal, 2021 The evolution of the Internet of Things has seen data sharing as one of its most useful applications in cloud computing. As eye-catching as this technology has been, data security remains one of the obstacles it faces since the wrongful use of data leads

Security and Communication Networks, 2011 ABSTRACTProxy re‐encryption (PRE) is a public key encryption that allows a semi‐trusted proxy with some information (a.k.a., re‐encryption key) to transform a ciphertext under one public key into another ciphertext under another public key. Because of this special property, PRE has many applications, such as the distributed file system.

Identity-based Searchable Encryption Scheme Supporting Proxy Re-encryption [PDF]
Jisuanji gongcheng, 2019 The existing Identity-based Encryption with Keyword Search (IBEKS) cannot share search permissions.Therefore,an Identity-based Proxy Re-encryption with Keyword Search (IBPKS) scheme in cloud environment is proposed.The identity-based encryption algorithm
