In this paper, we apply method and the thought of Obana's scheme, which was proposed in EUROCRYPT 2011, to present a new kind of verifiable attribute based encryption scheme. In our system, the center authority generates private keys and verification information at same time and distributes them to users. User is able to check correctness of private key through corresponding verification information. This is useful solution when some error happens in private key's generation or transmission. Two schemes are introduced in this paper, which are suitable for small attribute set or large one separately. In addition, we prove the security of our scheme under the selective security model.
