Fine-grained Home File Security Sharing Scheme Based on Attribute Encryption [PDF]
Jisuanji gongcheng, 2018 In the environment of home sharing,the user’s identity privacy may be leaked in the process of obtaining the file.To solve this problem,a fine-grained file sharing scheme based on attribute encryption is proposed.According to the needs of users,the ...

Biometric based Multi-Authority Inner Product Encryption for Electronic Health Record [PDF]
EAI Endorsed Transactions on Pervasive Health and Technology, 2020 INTRODUCTION: Attribute-based encryption enhances the security of electronic health records outsourced to the cloud. At thesame time, single authority attribute based encryption leads to user privacy breech and attribute management complexity.Multi ...

Attribute‐based encryption implies identity‐based encryption [PDF]
IET Information Security, 2017 In this study, the author formally proves that designing attribute‐based encryption schemes cannot be easier than designing identity‐based encryption schemes. In more detail, they show how an attribute‐based encryption scheme which admits, at least, and policies can be combined with a ...

Flexible Attribute-Based Encryption [PDF]
, 2012 In this paper, we propose a notion of flexible attribute-based encryption. Flexible attribute-based encryption is a variant of ciphertext-policy ABE, which allows one to loosen a decryption policy underlying a given ciphertext, if one knows some system-wide trapdoor information, without knowing its underlying plaintext message.

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-
