Conditional Privacy Using Re-encryption [PDF]
2008 IFIP International Conference on Network and Parallel Computing, 2008 This paper proposes, for the first time, the use of re-encryption scheme to improve users privacy in a privacy-enhancing system. Firstly, a secure protocol to distribute a re-encryption key from a user A to a service provider B, with the help of n referees, is proposed.

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

Lattice-Based proof of a shuffle [PDF]
, 2019 In this paper we present the first fully post-quantum proof of a shuffle for RLWE encryption schemes. Shuffles are commonly used to construct mixing networks (mix-nets), a key element to ensure anonymity in many applications such as electronic voting ...

Multi-key homomorphic proxy re-encryption scheme based on NTRU and its application
Tongxin xuebao, 2021 To improve the practicability of homomorphic encryption in the application of multi-user cloud computing, a NTRU-based multi-key homomorphic proxy re-encryption (MKH-PRE) scheme was constructed.Firstly, a new form of NTRU-based multi-key ciphertext was ...

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

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.
