White-Box Traceable Ciphertext-Policy Attribute-Based Encryption in Multi-Domain Environment

IEEE Access, 2019
In a ciphertext-policy attribute-based encryption (CP-ABE) system, the decryption keys are only related to attributes shared by multiple users and do not contain any identity information of their original holders.

Attribute-based publicly verifiable secret sharing

Cybersecurity
Can a dealer share a secret without knowing the shareholders? We provide a positive answer to this question by introducing the concept of an attribute-based secret sharing (AB-SS) scheme.With AB-SS, a dealer can distribute a secret based on attributes ...

A Survey of Research Progress and Development Tendency of Attribute-Based Encryption

The Scientific World Journal, 2014
With the development of cryptography, the attribute-based encryption (ABE) draws widespread attention of the researchers in recent years. The ABE scheme, which belongs to the public key encryption mechanism, takes attributes as public key and associates ...

Lattice-Based CP-ABE Access Control for SDS Constraint with Lazy Assignment of Attributes and Attribute Revocation

IET Information Security
Ciphertext-policy attribute-based encryption (CP-ABE) is a cryptographic scheme suitable for secure data sharing on cloud storage. The CP-ABE based on lattice theory has the property of resisting quantum attack. Some data objects uploaded to the cloud by
