摘要
针对传统森林火灾电子版档案数据中心化存储方式存在的数据泄露及数据难以共享问题,提出一种基于区块链技术的森林火灾档案数据共享方案。该方案融合区块链技术与星际文件系统(Interplanetary file system,IPFS),基于Hyperledger Fabric平台构建区块链网络,将完整的森林火灾档案数据经对称加密上传至IPFS网络,将生成的数据摘要信息经非对称加密上传至区块链网络,并在数据通信过程中采用代理重加密算法对其加密以确保数据安全。加密测试结果表明,经对称加密算法加密20 M火灾数据时比非对称加密算法快59.3 ms;通过数据存储试验数据发现,将20 M火灾数据上传至IPFS网络耗时4.117 5 ms;系统性能测试结果显示,基于区块链技术的森林火灾数据共享方案对森林火灾数据的查询上限为300 TPS。该方案在保证系统效率的前提下可实现森林火灾数据不可篡改性存储,且可通过增加网络中节点数量实现扩大森林火灾数据共享范围的目的。
To solve both problems of data leakage and sharing difficulties in the method of centralized storage of traditional electronic forest fire archival data,this paper puts forward a sharing scheme for forest fire archival data based on block chain technology.Combining block chain technology and interplanetary file system(IPFS),the scheme establishes a block chain network based on the Hyperledger Fabric platform,uploads complete forest fire archival data to the network of IPFS after symmetrical encryption and generated data summary information to the block chain network after asymmetric encryption,and adopts proxy re-encryption algorithm to encrypt the generated information in order to ensure data security in the process of data communication.The results of encryption tests show that the symmetric encryption algorithm can encrypt 20 M fire data 59.3 ms faster than do the asymmetric encryption algorithm;according to the data of data storage tests,it can be found that it takes 4.117 5 ms to upload 20 M fire data to the network of IPFS.The results of system performance tests show that the sharing scheme for forest fire archival data based on block chain technology has a query ceiling of 300 TPS for such data.On the premise of ensuring the efficiency of system,the scheme can realize the immutable storage of forest fire data and the purpose to expand the sharing scope of such data through the increase of nodes in the network.
