目前设计的星间通信网络安全加密系统加密深度低,导致通信误码率高,无法保证星间通信网络安全;引入区块链技术设计一种新的星间通信网络安全加密系统;选择性能最优的LEO类型的卫星放置在中层的卫星网络通信轨道中,其他类型的LEO卫星则各个成为单独的卫星网络分体系,处理主体系中的杂乱通信信号;构建地面用户之间的链路关系及卫星网络链路,实现高阶层卫星通过无线电链路或光纤链路对下一阶层的卫星覆盖,完成系统硬件设计;引用区块链分布式数字化身份加密技术,通过用户使用密钥对公钥的加密保护结构图定位通信网络的状态以及通信网络的加密状态,在区块链公开性的基础上增添了用户的密钥,通过用户的独有密钥使用户使用公共的星间通信网络进行通信,实现星间通信网络安全加密;实验结果表明,基于区块链技术的星间通信网络安全加密系统能够有效提高网络安全加密系统加密深度,降低误码率。

At present,the designed inter satellite communication network security encryption system has low encryption depth,which leads to high communication error rate and can not guarantee the security of inter satellite communication network.This paper introduces the blockchain technology to design a new inter satellite communication network security encryption system.In the LEO satellite network,the satellite communication network is divided into two layers:one is the satellite network,the other is the satellite network Cover,complete the system hardware design.Based on the block chain distributed digital identity encryption technology,the status of the communication network and the encryption state of the communication network are located through the encryption protection structure diagram of the public key with the block chain.The user’s key is added on the basis of the openness of the blockchain.The user can communicate with the public inter satellite communication network through the user’s unique key,so as to realize the security of the inter satellite communication network encryption.The experimental results show that the inter satellite communication network security encryption system based on blockchain technology can effectively improve the encryption depth of the network security encryption system and reduce the bit error rate.
