Conditional Identity-Based Broadcast Proxy Re-Encryption With Anonymity and Revocation

IEEE Transactions on Reliability
In recent years, many extended identity-based broadcast proxy re-encryption (IBPRE) schemes have been put forward. These schemes are flexible enough and feasible to various application scenarios, including conditional IBPRE, revocable IBPRE, and ...

Proxy Re-encryption with Unforgeable Re-encryption Keys

2014
Proxy re-encryption PRE provides nice solutions to the delegation of decryption rights. In proxy re-encryption, the delegator Alice generates re-encryption keys for a semi-trusted proxy, with which the proxy can translate a ciphertext intended for Alice into a ciphertext for the delegatee Bob of the same plaintext.

K-times Proxy Re-encryption

2011 Seventh International Conference on Computational Intelligence and Security, 2011
The traditional proxy re-encryption (PRE) or conditional proxy re-encryption (CPRE) can re-encrypt infinite times on the delegator's cipher text. However many practical applications do not need this property, they prefer the delegator can control on the times the proxy can re-encrypt.

Efficient Fine-Grained Data Sharing Based on Proxy Re-Encryption in IIoT

IEEE Transactions on Dependable and Secure Computing
With the development of the industrial Internet of Things (IIoT), the amount of data generated by industrial manufacturing equipment will increase. To reduce the cost of data management while achieving secure data sharing, data owners generally upload ...

A Novel Pairing-Free ECC-Based Ciphertext-Policy Attribute-Based Proxy Re-Encryption for Secure Cloud Storage

International Conference on Information Systems Security and Privacy
: Proxy re-encryption (PRE) is a cryptographic primitive enabling data owner to delegate ciphertext access rights without leaking underlying plaintext to honest-but-curious cloud servers. The delegation of ciphertext access rights enhances the efficiency

Re-Encryption Verifiability: How to Detect Malicious Activities of a Proxy in Proxy Re-Encryption

2015
In this paper, we introduce a new functionality for proxy re-encryption (PRE) that we call re-encryption verifiability. In a PRE scheme with re-encryption verifiability (which we simply call verifiable PRE, or VPRE), a receiver of a re-encrypted ciphertext can verify whether the received ciphertext is correctly transformed from an original ciphertext ...

Improved Proxy Re-Encryption With Delegatable Verifiability

IEEE Systems Journal, 2020
Proxy re-encryption cryptosystem enables proxy to re-encrypt the ciphertext and protects the privacy of the corresponding plaintext. Hence, this type of cryptosystem has found tremendous applications in data sharing in cloud computing, email forwarding, securing file systems, and so on.

Exfiltration-Resistant Proxy Re-Encryption for IoT Data Sharing in Unreliable Clouds

IEEE Transactions on Dependable and Secure Computing
The sharing of Internet of Things (IoT) data plays an extensive role in our everyday lives. Exploring secure and efficient methods for data sharing is a prominent area of research. Proxy re-encryption (PRE) in the cloud provides a solution.
