| 摘 要： | 目前，农业领域种质资源数据的共享管理工作大多采用中心化的数据共享模式，存在数据泄露、易篡改等问题。根据区块链技术具备的去中心化、安全可靠、防篡改的特点，提出一种基于区块链的种质资源数据安全共享系统，采用以太坊框架设计基于区块链的种质资源数据安全共享系统模型，针对用户身份数据和种质资源数据提出“IPFS+区块链”的链上链下协同存储模型，使用非对称加密技术确保种质资源数据安全性和用户身份数据隐私性，通过智能合约交互方式给出协同存储模型设计结果，展示模型的合理性。

| Abstract: | At present, data sharing and management of germplasm resources in agriculture field mostly adopts centralized data sharing mode, which has problems of data leakage, easy tampering and so on． According to characteristics of decentralization, safety, reliability, and tamper resistance of blockchain technology, it was proposed a germplasm resources data security sharing system based on blockchain technology with Ethereum framework． In secure blockchain-based germplasm resources data shared system model, an on-chain and off-chain collaborative storage model of "IPFS+blockchain" was put forward for user identity data and germplasm resources data． Asymmetric encryption technology was used to ensure germplasm resources data security and user identity data privacy through interaction of smart contracts． Then, design results of collaborative storage model were given, which was showed that this storage model was rational． |
