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 ...

Decentralizing Attribute-Based Encryption [PDF]
, 2011 We propose a Multi-Authority Attribute-Based Encryption (ABE) system. In our system, any party can become an authority and there is no requirement for any global coordination other than the creation of an initial set of common reference parameters. A party can simply act as an ABE authority by creating a public key and issuing private keys to different
