Decentralized Ciphertext-Policy Attribute-Based Encryption: A Post-Quantum Construction [PDF]
, 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 [PDF]
, 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 Practical Attribute-Based Document Collection Hierarchical Encryption Scheme in Cloud Computing
IEEE Access, 2019 Ciphertext-policy attribute-based encryption can provide fine-grained access control and secure data sharing to the data users in cloud computing. However, the encryption/decryption efficiency of existing schemes can be further improved when encrypting a

ciphertext policy attribute-based encryption from lattices: extended abstract [PDF]
, 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.

A Private‐Identifier System From Scalable Private Set Union
IET Information Security, Volume 2026, Issue 1, 2026.Modern data‐driven collaborations, such as spanning healthcare analysis and advertising attribution, need to merge large identifier sets without revealing which records overlap. A private set union (PSU) protocol enables two parties, each holding a private set X and Y, to securely compute their union X ∪ Y without revealing any additional information ...

Multi-Authority Ciphertext-Policy Attribute Based Encryption With Accountability
CoRR, 2020 Attribute-based encryption (ABE) is a promising tool for implementing fine-grained access control.To solve the matters of security in single authority, access policy public, not traceable of malicious user,we proposed a scheme of multi-authority. Moreover, multi-authority may bring about the collusion of different authorities.In order to solve these ...
