As a new cryptographic primitive, attribute-based cryptography is an attractive research topic in recent years. It provides a fine-grained and non-interactive access control mechanism of encrypted data and has great potential applications. Through an in-depth study of the major work on this topic, this paper presents a survey on the research status and development trend of attribute-based cryptography. It reviews the basic concepts of attribute-based cryptography, the development of provably secure schemes and some results of the most recent research. Finally, this paper discusses some problems that need to be solved in the future.
