摘　　要：通信安全保密工作,关系到国家的安全和利益,为了提高卫星通信的防窃听安全性,在多帧聚合安全编码基础上,本研究探究编码层级的优选方案,提出了一种基于多帧聚合编码层级动态跳变的安全协议设计。本方案设计安全编码模块由编码层级动态跳变的方式实现,跳变信息包含在通信的数据帧中,避免了通信双方的编码密钥管理,同时增加了窃听方破解信息的难度,提升系统安全性能。最后结合卫星通信DVB协议研究背景,探究安全协议的兼容性。Communication security is related to the security and interests of the country. In order to improve the security of satellite communication against eavesdropping, based on multi-frame aggregation security coding, this paper explores the preferred scheme of coding levels and proposes a security protocol design based on dynamic hopping of multi-frame aggregation coding levels. The scheme design security coding module is realized by coding level dynamic hopping, and the hopping information is included in the data frame of communication, which avoids the coding key management of both sides of communication, and increases the difficulty of eavesdropping party to decrypt the information, and improves the system security performance. Finally, the compatibility of security protocols is explored in the context of satellite communication DVB protocol research.
