Abstract: Government informatization has gradually moved from electronic and computerized information, to networked government information, and government big data (GBD) is a new stage in government informatization development. This stage features openness, sharing, dynamic, real-time and intelligence. In view of these features and the current situation of government big data development, this paper analyzes the technical and managemental challenges and basic security principles of the GBD platform development. Based on analysis, this paper proposes a new kind of reference architecture for GBD security based on an appropriate management organization structure. The paper also reviews related security regulatory mechanisms and security measures of this architecture. Compared to the US government's national institute of standards and technology (NIST) big data reference architecture, the proposed architecture is simpler, has a higher security level, clearer functional requirements, and is easier to implement. The proposed architecture can meet the actual current needs of big data security management, and has practical value in guiding the future government cloud platform, and security design and regulation of the GBD system.
