摘要: 卫星通信及应用已经成为当前社会生活的重要组成部分。为了解决卫星通信数据安全传输、信息隐私保护、接收端信息依赖等问题,基于低轨卫星气象数据传输的典型应用场景,提出了一套全代理同态加密传输模型(FPRM),并依据卫星通信系统架构将其实例化,从而设计卫星通信全代理同态可信传输系统与运行机制。该机制增加系统的通信安全和隐私保护,实现密文的可计算和传输全代理,有效融合卫星、商业数据中心以及互联网资源,降低运行成本,提高资源利用率,具有重要的实际意义和应用价值。最后,通过试验证明该模型的性能和数据扩展性具有可行性。

Abstract: Satellite communication and its applications have become an important part in current social life. In order to ensure the secure transmission of satellite communication data, privacy protection of information, and to sovle the problem of dependency on the receiving side, a set of full proxy reencryption transmission model (FPRM) was proposed based on typical application scenarios of the transmission of low orbit constellation meteorological data. It was instantiated according to the satellite communication architecture to design a trusted proxy homomorphic transmission system. Computable ciphertext and full proxy transmission have been implemented by adding security of system communication and privacy protection to the mechanism. It is of great practical significance and values to integrate satellite, commercial data centers and Internet resources to reduce costs and improve resource utilization. Finally, it proves that the performance and data scalability of this model are feasible through experiments.
