With the wide application of Internet Things (IoT), storing large amounts IoT data and protecting privacy has become a meaningful issue. In general, access control mechanism is used to prevent illegal users from accessing private data. However, traditional schemes face some non-ignorable problems, such as only supporting coarse-grained control, risk centralization, high trust issues. this paper, an attribute-based scheme using blockchain technology proposed. To address these encryption (ABE) promising solution for encrypted control. Firstly, we utilize construct decentralized scheme, which can grant with transparency traceability. Furthermore, our also guarantees policies attributes on network. Secondly, optimize ABE makes size system parameters smaller improves efficiency algorithms. These optimizations enable proposed supports attribute universe requirements in environments. Thirdly, prohibit impersonation replay attacks, design challenge-response verify ownership attributes. Finally, evaluate security performance scheme. And comparisons other related show advantages Compared existing schemes, more comprehensive advantages, universe, full security, expressive policy, policy hiding.
