Adaptively Secure Proxy Re-encryption

2019
A proxy re-encryption (PRE) scheme is a public-key encryption scheme that allows the holder of a key pk to derive a re-encryption key for any other key pk′. This re-encryption key lets anyone transform ciphertexts under pk into ciphertexts under pk′ without having to know the underlying message, while transformations from pk′to pk should not be ...

A Pairing-Free Data-Sharing Scheme Based on Certificateless Conditional Broadcast Proxy Re-Encryption Suitable for Cloud-Assisted IoT

IEEE Internet of Things Journal
In Cloud-Assisted IoT (CAIoT), the large amounts of data generated by devices and sensors need to be shared and stored efficiently and securely. broadcast proxy re-encryption (BPRE) technology ensures data privacy and enables efficient sharing.

Proxy Re-encryption with Delegatable Verifiability

2016
Proxy re-encryption is a public key encryption technique that allows a proxy to perform re-encryption without exposing the corresponding plaintext. As a result, proxy re-encryption has increased utility, and can be used in a number of fields including cloud computing.

Weighted Attribute Based Conditional Proxy Re-Encryption in the Cloud

Computers, Materials & Continua
: Conditional proxy re-encryption (CPRE) is an effective cryptographic primitive language that enhances the access control mechanism and makes the delegation of decryption permissions more granular, but most of the attribute-based conditional proxy re ...

Identity-Based Conditional Proxy Re-Encryption

2011 IEEE International Conference on Communications (ICC), 2011
This paper proposes a new cryptographic primitive, named identity-based conditional proxy re-encryption (IBCPRE). In this primitive, a proxy with some information (a.k.a. re-encryption key) is allowed to transform a subset of ciphertexts under an identity to other ciphertexts under another identity.

Multi-Use Unidirectional Proxy Re-Encryption

2011 IEEE International Conference on Communications (ICC), 2011
This paper presents the first multi-use unidirectional proxy re-encryption scheme proven-secure against chosenciphertext attacks and collusion attacks in the standard model. Although our proposal features a linear ciphertext size and decryption time in the number of translations, we emphasize that it is the first multi-use and unidirectional ...

Public Trace-and-Revoke Proxy Re-Encryption for Secure Data Sharing in Clouds

IEEE Transactions on Information Forensics and Security
Proxy re-encryption (PRE), as a promising cryptographic primitive for secure data sharing in clouds, 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 ...
