【摘要】 通信安全已成为影响空间科学技术进一步发展的重要因素之一。根据通信系统安全体系结构设计原则和方法,分析空间通信的特征和空间网络存在的各种安全威胁,提出一个将多级多层密钥管理以及混合式身份认证方法相结合的网络认证模型,从而对CCSDS标准的安全部分给予有力补充,更加全面高效地实现空间通信网安全认证。更多还原

【Abstract】 Communication Security problem is a great challenge for the further development of space science and technology.Based on the design principle and method of communication systems security,characteristics of space communications and threats for space networks are analysed.An authentication model is proposed for the space communication networks. This model is based on multi-level key management and composite identity authentication to give forceful supplement for the secure part of the CCSDS standard.The proposed model is efficient and has practical significance.更多还原
