CP‐ABE with outsourced decryption and directionally hidden policy

Security and Communication Networks, 2016
AbstractCiphertext‐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 that the access policy itself may disclose some privacies of the users.
