摘要：

Currently, Attribute-Based Encryption (ABE) schemes with Hidden Access Structures are proposed in groups of a composite order or only proved selectively secure without random oracles. Using asymmetric pairings, an anonymous ciphertext-policy attribute-based encryption scheme is proposed in a prime order bilinear group in this paper. The scheme is proved fully secure under the standard model based on the asymmetric decisional bilinear Diffie-Hellman (DBDH) assumption. Moreover, it has a constant size private key, a ciphertext and the number of pairing operations. The proposed scheme improves the security and efficiency of ABE schemes with hidden access structures when compared with the ones in groups of a composite order. ©, 2015, Science Press.
