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.

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.

Public Trace-and-Revoke Proxy Re-encryption
, 2022 Proxy re-encryption (PRE), as a promising cryptographic primitive for secure data sharing in cloud, has been widely studied for decades. PRE allows the proxies to use the re-encryption keys to convert ciphertexts computed under the delegator’s public key

Shared and Searchable Encrypted Data for Untrusted Servers [PDF]
, 2008 Current security mechanisms pose a risk for organisations that outsource their data management to untrusted servers. Encrypting and decrypting sensitive data at the client side is the normal approach in this situation but has high communication and ...

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
