Attribute-based encryption scheme with multi-keyword search and supporting attribute revocation in cloud storage. [PDF]
PLoS ONE, 2018 We propose an attribute-based encryption scheme with multi-keyword search and supporting attribute revocation in cloud storage environment, in which binary attributes and AND-gate access policy are used. Our proposal enjoys several advantages.

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-

Revocable Ciphertext-Policy Attribute-Based Encryption in Data Outsourcing Systems from Lattices
Jisuanji kexue yu tansuo, 2020 Attribute-based encryption mechanism is widely used in outsourcing environment because of its charac-teristics of “one-to-many” communication. However, users attributes often change dynamically.

Constant-Ciphertext-Size Dual Policy Attribute Based Encryption [PDF]
, 2012 Dual-Policy Attribute Based Encryption (DP-ABE), proposed in 2009, is a combination of two variants, Ciphertext Policy-ABE (CP-ABE) and Key Policy-ABE (KP-ABE), where an encryptor can associate the data simultaneously with both a set of objective ...
