英文摘要	The record books on the traditional blockchain of global transaction information for any nodes joining the blockchain system are public. This paper introduces searchable encryption and proxy re-encryption to propose blockchain data sharing scheme based on searchable proxy re-encryption, which solves the problems of conventional blockchain data privacy disclosure and rapid query. Firstly, we define the level of data users on the blockchain transactions to achieve access control of data. Secondly, to lighten the burden of storage blockchain, we use proxy encryption to encrypt the data before storing it in the external database, which achieves data sharing. Furthermore, binary search is performed by computing the inner product of the search token vector and index vector. Finally, we demonstrate the security and effectiveness of our scheme under the model of oracle. © 2021. All Rights Reserved
