RLWE-based key-policy ABE scheme
Tongxin xuebao, 2016 Based on the attribute-based encryption(ABE) scheme which was proposed by Brakerski and constructed on the LWE problem,a RLWE-based key-policy ABE scheme was presented.Efficiency and key size of this scheme over-takes old ones which are based on the LWE ...

Flexible Attribute-Based Encryption [PDF]
, 2012 In this paper, we propose a notion of flexible attribute-based encryption. Flexible attribute-based encryption is a variant of ciphertext-policy ABE, which allows one to loosen a decryption policy underlying a given ciphertext, if one knows some system-wide trapdoor information, without knowing its underlying plaintext message.

Revocable attribute-based proxy re-encryption
Journal of Mathematical Cryptology, 2021 Attribute-based proxy re-encryption (ABPRE), which combines the notions of proxy re-encryption (PRE) and attribute-based encryption (ABE), allows a semi-trusted proxy with re-encryption key to transform a ciphertext under a particular access policy into ...

Multi-authority attribute-based encryption access control model for cloud storage
Tongxin xuebao, 2015 The existing attribute-based encryption access control studies are mostly based on single authority,and this scheme is apt to be under attack to cause exposure of secret keys.Thus,a multi-authority access control model PRM-CSAC is proposed.Based on CP ...

Enhancing Attribute-Based Encryption with Attribute Hierarchy [PDF]
Mobile Networks and Applications, 2009 Attribute-based encryption (ABE) has been envisioned as a promising cryptographic primitive for realizing secure and flexible access control. However, ABE is being criticized for its high scheme overhead as extensive pairing operations are usually required. In this paper, we focus on improving the efficiency of ABE by leveraging a previously overlooked

Provably Secure Ciphertext-Policy Attribute-Based Encryption from Identity-Based Encryption [PDF]
Journal of Universal Computer Science, 2019 Ciphertext-policy attribute-based encryption (CP-ABE) is an access control mechanism where a data provider encrypts a secret message and then sends the ciphertext to the receivers according to the access policy which she/he decides.

Targeted Homomorphic Attribute-Based Encryption
, 2016 In key-policy attribute-based encryption ABE, messages are encrypted respective to attributes x, and keys are generated respective to policy functions f. The ciphertext is decryptable by a key only if $$fx=0$$fx=0. Adding homomorphic capabilities to ABE is a long standing open problem, with current techniques only allowing compact homomorphic ...
