摘要: 针对CCSDS分包遥控(Telecommand)系统所面临的安全威胁，结合空间通信环境的特点，通过对各种认证加密算法(AEAD)的性能分析，提出将GCM(Galois/Counter Mode)认证加密算法应用于分包遥控系统数据链路层的方案。设计并实现了基于OPNET的CCSDS分包遥控系统仿真框架。仿真结果表明，在不影响吞吐量性能的前提下，GCM认证加密算法能有效地保证分包遥控数据的机密性、完整性和信息来源的合法性，并且具有数据处理性能高、系统开销小的特点。Abstract: Risk analyses performed by several space agencies have provided indications of the impact of different threats on several categories of space missions in the context of space communication. A method of integrating the GCM (Galois/Counter Mode) into data link layer of Telecommand protocol is proposed after the performance analysis of various AEAD (Authenticated Encryption with Associated Data) techniques. The simulation framework of CCSDS Telecommand systems is designed and implemented with OPNET. The simulation results show, AEAD techniques can effectively provide the confidentiality, integrity and authentication of Telecommand information with no decrease to the throughput performance.
