摘要
针对传统云存储系统中存在的高运营成本和依赖第三方等问题,提出一种基于区块链技术的数据存储系统,该系统以区块链作为分布式云存储的底层支撑,通过关键字搜索服务提供安全的分布式数据存储。在该存储系统中,用户对数据加密并上传到云节点,同时使用加密技术保证数据可用性,系统支持对加密数据集进行私有关键字搜索。用户拥有授权权限,使得他人有权限搜索用户数据。与现有云存储数据系统比较,该系统能提供匿名、低成本和去可信第三方的云存储服务。
Aiming at the high operating cost and dependence on third parties in traditional cloud storage systems,a data storage system based on blockchain technology was proposed. The system uses blockchain as the underlying support of distributed cloud storage and provides secure distributed data storage through keyword search service. In this storage system,users encrypt and upload data to cloud nodes,and use encryption technology to ensure data availability. The system supports private keyword search for encrypted data sets. Finally,users have authorization rights,so that others have the right to search user data. Compared with the existing cloud storage data systems,the results show that the system can provide anonymous,low-cost and unused trusted third-party cloud storage services.
