摘　　要：以实现数据安全存储和共享为目的,设计基于IPFS和区块链技术的可信数据安全存储和共享系统。系统利用数据存储层内的安全存储节点存储安全数据,然后以区块链网络层内由若干个区块组成的以太坊作为数据安全传输的网络,将安全数据传输到数据管理层内,数据管理层负责执行数据存储、数据加密、区块链调用的逻辑运算功能,并与接口服务层相连,与管理员、数据拥有者和数据请求者之间实现数据访问控制,数据请求服务等数据安全传输和共享功能。实验结果表明:所提系统运行时的耦合度数值较高,系统稳定性能好;在对数据进行加密时的执行效率较好,可有效控制数据访问和共享,应用性较强。With the aim of achieving secure data storage and sharing,a trusted data secure storage and sharing system based on IPFS and blockchain technology is proposd.The system uses the secure storage node in the data storage layer to store security data,and then uses Ethereum,which is composed of several blocks in the blockchain network layer,as the network for secure data transmission,to transmit security data to the data management layer.The management layer is responsible for performing the logical operation functions of data storage,data encryption,and blockchain invocation,and connecting with the interface service layer,and connecting with the administrator.It implements data access control,data request services,and other data security transmission and shares functions between data owners and data requesters.The experimental results show that the coupling value of the system during operation is higher,and the system has good stability performance.The execution efficien-cy is good when encrypting data,which can effectively control data access and sharing,and has stronger applicability.
