摘要
空间数据安全分发需要针对空间环境条件变化进行数据安全传输方案优化。以数据质量为核心,基于信息属性对空间数据传输过程进行建模,并提出适应空间环境的数据安全保护策略和方法。设计基于信息属性感知的空间数据安全分发机制。结合数据加密和认证对空间数据安全分发进行优化与评估。对空间数据信息属性及各种约束条件与安全传输机制间的制约规律进行分析,对算法的鲁棒性、可伸缩性和可靠性进行理论分析和仿真验证,并验证安全传输策略和方法的可行性。
An optimal secure transmission scheme of space data is designed by optimized the secure distribution of the space observation data in view of the change of source-channel condition. Various sourcechannel models are built based on the optimization objective of data quality,and then the data protection strategy and approach based on joint source-channel and secure coding are proposed. A quality evaluation and distribution model of space observation data is established,and the secure distribution of space observation data under separated source-channel coding and the encryption-authentication distribution of space observation data under joint source-channel coding are optimized and evaluated. The algorithms are analyzed and simulated. The data protection strategy and approach are validated in robustness,scalability and reliability.
