Abstract: Blockchain is a distributed ledger that integrates key technologies such as distributed storage,peer-to-peer transmission,consensus mechanism,cryptographic algorithm and smart contract.It has the characteristics of decentralization,non-tampering,transparency and so on.In recent years,security problems of blockchain have gradually emerged,hindering the development of blockchain applications.This paper introduces the basic concept and security model of the blockchain,and analyzes the security problems of the blockchain.Then,based on the attribute-based cryptography,the various researches of the blockchain security technology are analyzed from the three aspects of access control,key management,and data privacy protection,and the characteristics of the main solutions are discussed.Finally,we summarize the research progress of the blockchain security technology based on the attribute-based cryptography,and discuss the future research work.

Key words: blockchain security, cryptography, attribute-based encryption, attribute-based signature
