Ciphertext-Policy Attribute-Based Encryption [PDF]
2007 IEEE Symposium on Security and Privacy (SP '07), 2007 In several distributed systems a user should only be able to access data if a user posses a certain set of credentials or attributes. Currently, the only method for enforcing such policies is to employ a trusted server to store the data and mediate access control.

Decentralizing Attribute-Based Encryption [PDF]
IACR Cryptology ePrint Archive, 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
