CP-ABE Scheme with Attribute Revocation Under Environment of Multi-attribute Authority [PDF]
Jisuanji gongcheng, 2018 For the attribute-based encryption scheme,a single authority has the problem of low efficiency and easy disclosure of user keys.Through the establishment of a decentralized attribute authority and agent reencryption technology,a Ciphertext-policy ...

Two-Factor Data Access Control With Efficient Revocation for Multi-Authority Cloud Storage Systems
IEEE Access, 2017 Attribute-based encryption, especially for ciphertext-policy attribute-based encryption, can fulfill the functionality of fine-grained access control in cloud storage systems. Since users' attributes may be issued by multiple attribute authorities, multi-

Decentralizing Attribute-Based Encryption [PDF]
, 2011 We propose a Multi-Authority Attribute-Based Encryption (ABE) system. In our system, any party can become an authority and there is no requirement for any global coordination other than the creation of an initial set of common reference parameters. A party can simply act as an ABE authority by creating a public key and issuing private keys to different
