Weighted Attribute-Based Proxy Re-Encryption Scheme with Distributed Multi-Authority Attributes [PDF]
SensorsExisting attribute-based proxy re-encryption schemes suffer from issues like complex access policies, large ciphertext storage space consumption, and an excessive authority of the authorization center, leading to weak security and controllability of data

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 ...

Provably Secure Identity-based Conditional Proxy Re-encryption Scheme [PDF]
Jisuanji gongcheng, 2017 The conditional proxy re-encryption based on the traditional public key cryptosystem is mature,but the Identity-based Proxy Re-encryption(IBPRE) scheme,controlling agents’ permissions from the fine-grained level is a problem needed to be solved.Thus,this

Efficient Unidirectional Proxy Re-Encryption [PDF]
, 2010 Proxy re-encryption (PRE) allows a semi-trusted proxy to convert a ciphertext originally intended for Alice into one encrypting the same plaintext for Bob. The proxy only needs a re-encryption key given by Alice, and cannot learn anything about the plaintext encrypted.

RSA-TBOS signcryption with proxy re-encryption [PDF]
Proceedings of the 8th ACM workshop on Digital rights management, 2008 The recent attack on Apple iTunes Digital Rights Management [17] has brought to light the usefulness of proxy re-encryption schemes for Digital Rights Management. It is known that the use of proxy re-encryption would have prevented the attack in [17]. With this utility in mind and with the added requirement of non-repudiation, we propose the first ever

Group-Based Proxy Re-encryption Scheme [PDF]
, 2009 Recently, proxy re-encryption scheme received much attention. A proxy re-encryption used for divert ciphertext from one group to another without revealing underlying plaintext is proposed in this paper. The scheme is bidirectional and any member can independently decrypt the ciphertext encrypted to its group.

Attribute-based proxy re-encryption scheme with multiple features [PDF]
Tongxin xuebao, 2019 A ideal proxy re-encryption scheme has five features,such as one-way encryption,non-interaction,repeatability,controllability and verifiability.The existing schemes,however,have only two or three of the five features,which reduces the utility of them to ...
