Decentralized Ciphertext-Policy Attribute-Based Encryption: A Post-Quantum Construction

open access: yes, 2017
In Ciphertext Policy Attribute-Based Encryption (CP-ABE) system, a set of attributes is associated with the private keys of each user. Also, the ciphertext is attached with a policy which is defined over that set of attributes.

Ciphertext-Policy Attribute-Based Proxy Re-Encryption with Non-Interactivity from Lattices

open access: yes, 2022
Along with the gradual increase in data encryption applications, it is required to trans- form access permissions of ciphertexts in some scenarios. Combining the proxy re-encryption mechanism with the attribute-based encryption mechanism can reduce the ...

A ciphertext-policy attribute-based proxy re-encryption scheme for data sharing in public clouds

open access: yes, 2014
Ciphertext-policy attribute-based proxy re-encryption (CP-ABPRE) extends the traditional Proxy Re- Encryption (PRE) by allowing a semi-trusted proxy to transform a ciphertext under an access policy to another ciphertext with the same plaintext under a ...

Multi-authority attribute-based encryption with efficient revocation

open access: yesTongxin xuebao, 2017
Multi-authority attribute-based encryption was very suitable for data access control in a cloud storage environment.However,efficient user revocation in multi-authority attribute-based encryption remains a challenging problem that prevents it from ...

Security analysis of a privacy-preserving decentralized ciphertext-policy attribute-based encryption scheme

open access: yes, 2016
As it does not require a central authority or the cooperation among multiple authorities, decentralized attribute-based encryption is an efficient and flexible multi-authority attribute-based encryption system.
