摘　　要：区块链的每个节点都具备资源访问的权限,以明文存储的方式不能够确保数据的机密性。为解决区块链中的数据查找隐私暴露的问题,本文设计一项可搜索加密的区块链设计方案。该方案将区块链技术和可搜索加密相结合,并采用智能合约充当可靠的第三方搜索工具,从而限制了服务器在下发数据时的恶意行为,有效地解决了区块链存在的数据检索和隐私泄露等问题。Each node in the blockchain has access to resources,and storing data in plain text cannot ensure the confidentiality of the data.To address the issue of privacy exposure in data search in blockchain,this article designs a searchable encrypted blockchain design scheme.This scheme combines blockchain technology with searchable encryption,and uses smart contracts as reliable third-party search tools to limit malicious behavior of servers when distributing data,effectively solving the problems of data retrieval and privacy leakage in blockchain.
