Ciphertext-Policy Attribute-Based Broadcast Encryption Scheme [PDF]
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.

Data Querying with Ciphertext Policy Attribute Based Encryption
Data encryption limits the power and efficiency of queries. Direct processing of encrypted data should ideally be possible to avoid the need for data decryption, processing, and re-encryption. It is vital to keep the data searchable and sortable. That is, some information is intentionally leaked.

Revocable Ciphertext-Policy Attribute-Based Encryption in Data Outsourcing Systems from Lattices
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]
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 ...

Efficient Privacy-Preserving Access Control of Mobile Multimedia Data in Cloud Computing
With the nature of allowing the encryptor to define the access policy before encrypting a message, Ciphertext-policy attribute-based encryption (CP-ABE) has been widely adopted as a primitive to design cloud-assisted mobile multimedia data sharing system.

Attribute-based encryption scheme with multi-keyword search and supporting attribute revocation in cloud storage. [PDF]
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.
