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 ...

Multi-authority attribute-based encryption scheme with policy dynamic updating
Tongxin xuebao, 2017 Attribute-based encryption (ABE) is a new cryptographic technique which guarantees fine-grained access control of outsourced encrypted data in the cloud environment.However,a key limitation remains,namely policy updating.Thus,a multi-authority attribute ...

Efficient revocable attribute-based encryption scheme
Tongxin xuebao, 2019 In the existing solutions,the time-based scheme is difficult to achieve immediate revocation,and the third-party-based scheme often requires re-encryption,which needs large amount of calculation and doesn’t apply to mas-sive data.To solve the problem,an ...

Privacy preserving cloud data access with multi-authorities [PDF]
2013 Proceedings IEEE INFOCOM, 2013 Cloud computing is a revolutionary computing paradigm which enables flexible, on-demand and low-cost usage of computing resources. Those advantages, ironically, are the causes of security and privacy problems, which emerge because the data owned by different users are stored in some cloud servers instead of under their own control.

A Scalable Framework for Stylometric Analysis of Multi-author Documents [PDF]
, 2018 Stylometry is a statistical technique used to analyze the variations in the author’s writing styles and is typically applied to authorship attribution problems. In this investigation, we apply stylometry to authorship identification of multi-author documents (AIMD) task. We propose an AIMD technique called Co-Authorship Graph (CAG) which can be used to

Multi-authority attribute-based encryption access control model for cloud storage
Tongxin xuebao, 2015 The existing attribute-based encryption access control studies are mostly based on single authority,and this scheme is apt to be under attack to cause exposure of secret keys.Thus,a multi-authority access control model PRM-CSAC is proposed.Based on CP ...
