摘要
建立政府数据共享平台可以为大数据在未来政府的应用打下基础,但是建立政府数据共享平台给政府信息系统带来了很多新的安全问题。文章研究了两大安全问题,一是针对共享数据安全管理问题提出了二级管理安全模型;二是为了防止共享数据的二次非法授权访问提出了采用数据密封机制,对共享数据进行加密,加密密钥与数据授权使用系统的软硬件信息相关联。
Big data has great value. Applying big data in government can provide a reference to the government when making decisions. Besides, new applications will be created by applying big data so that the government can offer more and better services to the people. The establishment of government data sharing platform can lay the foundation for the application of big data in government in the future. But the government data sharing platform will bring many new security problems. In this paper, two security problems are studied. To manage the shared data securely, this paper proposes two-level management model. And to prevent the illegal secondary authorization of the shared data, this paper proposes sealed data mechanism that encrypts the shared data with the key associated the system hardware and software information.
