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 ...

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

Constant Ciphertext Length in CP-ABE
IACR Cryptol. ePrint Arch., 2012 Ciphertext policy attribute based encryption (CP-ABE) is a technique in which user with secret key containing attributes, only able to decrypt the message if the attributes in the policy match with the attributes in secret key. The existing methods that use reasonably computable decryption policies produce the ciphertext of size at least linearly ...
