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.

Ciphertext-Policy Attribute-Based Broadcast Encryption Scheme [PDF]
, 2011 In this work, we design a new attribute-based encryption scheme with the revocation capability. In the proposed schemes, the user (broadcaster) encrypts the data according to an access policy over the set of attributes, and a list of the identities of revoked users.

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.
