Lattices-Inspired CP-ABE from LWE Scheme for Data Access and Sharing Based on Blockchain
Applied Sciences, 2023 To address the quantum attacks on number theory-based ciphertext policy attribute-based encryption (CP-ABE), and to avoid private key leakage problems by relying on a trustworthy central authority, we propose a lattice-inspired CP-ABE scheme for data ...

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.

A CP-ABE Scheme Supporting Arithmetic Span Programs [PDF]
Security and Communication Networks, 2020 Attribute-based encryption achieves fine-grained access control, especially in a cloud computing environment. In a ciphertext-policy attribute-based encryption (CP-ABE) scheme, the ciphertexts are associated with the access policies, while the secret keys are determined by the attributes. In recent years, people have tried to find more effective access
