基于联盟区块链的高校数据平台安全共享研究

Research on colleges and universities data platform secure sharing based on alliance blockchain

为打破数据孤岛,确保学校各部门之间高校数据共享时不被非法访问,提出一种基于联盟区块链的高校数据平台安全共享方法。在分析联盟区块链模式下高校数据平台共享的技术架构后,设计一种基于联盟区块链智能合约的高校数据平台安全共享机制,此机制使用基于改进RSA加密算法的数据安全共享方法为数据发布方提供数据加密服务,为数据需求方提供数据解密服务。双方的数据共享交易主要由联盟区块链智能合约完成,智能合约按照高校数据共享的加解密信息授权结果、共享约束条件,在无第三方干预的情况下进行数据共享交易。经测试,使用所提方法进行业务数据共享时,提升了数据传输速率,且业务数据非法提取次数为0。

In order to break the data island and ensure that colleges and universities data sharing between various departments will not be accessed illegally,a method of colleges and universities data platform secure sharing based on alliance blockchain is proposed.After analyzing the technical architecture of colleges and universities data platform sharing under the alliance blockchain mode,a colleges and universities data platform secure sharing mechanism based on alliance blockchain smart contract is designed.In this mechanism,a method of data secur sharing based on improved RSA encryption algorithm is used to provide data encryption services for data publishers and data decryption services for data demanders.The data sharing transaction between both parties is mainly completed by means of the alliance blockchain smart contract.The smart contract can conduct data sharing transactions without third-party intervention in accordance with the authorization results of encryption and decryption information and sharing constraints of the affairs data sharing.After testing,it is found that when the proposed method is used for the colleges and universities data sharing,the data transmission rate can be increased and the number of illegal extraction of school affair data is 0.
