In this paper, we construct an oriented user group verifiable attribute-based encryption (OG-ABEv) scheme. Our scheme not only maintains on the security of previous ABE schemes, but also enhances two functions: (1) It integrates user group into the ABE scheme, thereby strengthening the confidentiality of data sharing and reducing excessive centralization of user rights; (2) It provides a verification method to supervising the central authority (CA). It also allows users to immediately check the correctness of the attribute keys and allows semi-trusted or untrusted CA be in our system. We formalize the concept of OG-ABEv and prove our scheme.
