A Distributed Attribute-Based Proxy Re-Encryption Scheme for Data Sharing in IoT

IEEE International Conference on Big Data Security on Cloud
Attribute-based encryption (ABE) offers finegrained access control in the Internet of Things but also imposes significant performance overhead on devices.

A Homomorphic Proxy Re-encryption from Lattices

2016
In this paper, we present a unidirectional homomorphic proxy re-encryption PRE scheme from learning with errors assumption, which can homomorphically evaluates ciphertexts at input or output side, no matter ciphertexts are fresh or re-encrypted re-encrypted ciphertexts can come from different identities.

An Approach for Securing IoT Data using Blockchain and Proxy Re-Encryption

2024 International Conference on Knowledge Engineering and Communication Systems (ICKECS)
The development of Internet of Things (IoT) devices has resulted in exponential data generation, creating substantial problems to guaranteeing the security and privacy of sensitive information.

Anonymous ID-Based Proxy Re-Encryption

2012
ID-based proxy re-encryption (IBPRE) allows a proxy with some information (a.k.a. re-encryption key) to transform the ciphertext under one identity to another ciphertext under another identity. These two ciphertexts can yield the same plaintext, while the proxy cannot get any information of the plaintext.

On Quorum Controlled Asymmetric Proxy Re-encryption

1999
We present a scheme for quorum controlled asymmetric proxy re-encryption, with uses ranging from efficient key distribution for pay-tv to email applications. We prove that the scheme, which is based on El-Gamal encryption, leaks no information as long as there is no dishonest quorum of proxy servers.
