Constant-Size Ciphertext Attribute-based Encryption from Multi-Channel Broadcast Encryption [PDF]

, 2016
Attribute-based encryption (ABE) is an extension of traditional public key encryption in which the encryption and decryption phases are based on user's attributes.

Research on Ciphertext-Policy Attribute-Based Encryption with Attribute Level User Revocation in Cloud Storage [PDF]

, 2017
Attribute-based encryption (ABE) scheme is more and more widely used in the cloud storage, which can achieve fine-grained access control. However, it is an important challenge to solve dynamic user and attribute revocation in the original scheme.

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

, 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 ...

mRLWE-CP-ABE: A revocable CP-ABE for post-quantum cryptography

Journal of Mathematical Cryptology
We address the problem of user fast revocation in the lattice-based Ciphertext Policy Attribute-Based Encryption (CP-ABE) by extending the scheme originally introduced by Zhang and Zhang [Zhang J, Zhang Z.

Efficient and Provable Secure Ciphertext-Policy Attribute-Based Encryption Schemes [PDF]

, 2008
In a ciphertext-policy attribute-based encryption (CP-ABE) scheme, the data is encrypted under an access policy defined by a user who encrypts the data and a user secret key is associated with a set of attributes which identify the user.

Mediated Ciphertext-Policy Attribute-Based Encryption and its Application (extended version) [PDF]

, 2009
In Ciphertext-Policy Attribute-Based Encryption (CP-ABE), a user secret key is associated with a set of attributes, and the ciphertext is associated with an access policy over attributes.

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

, 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.
