Data sharing in the digital world raises concerns about data security and privacy, especially in a multi-authority environment where there are multiple data ...
The framework operates on Blockchain technology and multi-authority attribute-based encryption. Our framework protects against malicious single authority who ...
May 25, 2022 · Our framework protects against malicious single authority who aims to grant permission to users to the shared data. Moreover, we optimize the ...
In this paper, we propose a MA-ABE scheme, which combines a global ID model, a two-stage sampling technique on a lattice and a monotonous linear secret sharing ...
In this paper, we introduce an access control policy model for the multi-authority system, which enables attribute authorities to control the security setting.

This paper proposes a multi-authority attribute-based access control scheme by using Ethereum's smart contracts. In the proposed scheme, Ethereum smart ...
A multi-authority CP-ABE system is said to be correct if whenever GP is ob- tained from the global setup algorithm, CT is obtained from the encryption algorithm ...
Missing: Authorization Framework.
We first design an efficient multi-authority CP-ABE scheme that does not require a global authority and can support any LSSS access structure. Then, we prove ...
Missing: Decentralized Authorization
We allow any number of attribute authorities to be corrupted, and guarantee the security of encryption as long as the required attributes cannot be obtained ...
