ABSTRACT
At Eurocrypt 2005, Sahai and Waters [7] introduced the concept of attribute-based encryption (ABE). ABE enables public key based one-to-many encryption and is envisioned as a promising cryptographic primitive for realizing scalable and fine-grained access control systems. There are two kinds of ABE schemes [1], key-policy ABE (KP-ABE) and ciphertext-policy ABE (CP-ABE) schemes. This paper, our concern is on the latter.

CP-ABE with outsourced decryption and directionally hidden policy
Ciphertext-policy attribute-based encryption CP-ABE is a novel cryptographic primitive for access controlling. However, the existing CP-ABE schemes are very inefficient as the decryptions involve many expensive pairing operations. Another drawback is ...
Efficient attribute-based signature and signcryption realizing expressive access structures

Fully secure cipertext-policy hiding CP-ABE
ISPEC'11: Proceedings of the 7th international conference on Information security practice and experienceIn ciphertext-policy attributed-based encryption (CP-ABE), each ciphertext is labeled by the encryptor with an access structure (also called ciphertext policy) and each private key is associated with a set of attributes. A user should be able to decrypt ...
