ciphertext policy attribute-based encryption from lattices: extended abstract

, 2012
Sahai and Waters [6] proposed Attribute-Based Encryption (ABE) as a new paradigm of encryption algorithms that allow the sender to set a policy describing who can decrypt a particular ciphertext.

Ciphertext policy hidden access control scheme based on blockchain and supporting data sharing

Tongxin xuebao, 2022
Objectives: Although the traditional attribute-based encryption scheme achieves one-to-many access control,there are still challenges such as single point of failure,low efficiency,no support for data sharing,and privacy leakage.To solve these problems,a

A Ciphertext-Policy Attribute-Based Proxy Re-Encryption with Chosen-Ciphertext Security [PDF]

, 2013
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 the one with the same plaintext under another access ...

Ciphertext-Policy Attribute Based Encryption with Selectively-Hidden Access Policy [PDF]

, 2021
In conventional Ciphertext-Policy Attribute-Based Encryption (CP-ABE), the access policy appears in plaintext form that might reveal confidential user information and violate user privacy.

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.

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.

Ciphertext policy attribute-based encryption scheme supporting direct revocation

Tongxin xuebao, 2016
In order to support fine-grained attribute revocation in direct revocation mode an attribute-based encryption scheme with efficient revocation was proposed.The model of ABE supporting attribute revocation was given,and a con-crete scheme was constructed ...
