摘　　要：卫星互联网具有覆盖范围广、通信时延低、传输容量大、地域影响小等优势,能为全球用户提供无处不在的互联网接入服务。但是卫星网络与地面网络的异构性,卫星网络的信道开放、节点暴露等特点会对网络接入和资源管理造成安全威胁。针对卫星互联网的安全问题,提出基于区块链的多层卫星互联网安全管理架构。区块链作为一种分布式账本技术,以块链式数据结构来验证和存储数据,通过密码学方法保证数据块的不可篡改,能实现网络安全接入和资源可信管理,为卫星互联网提供信息安全防护。通过将区块链技术与卫星互联网融合,提高卫星互联网的安全性。Satellite internet have the advantages of wide coverage,low latency,large transmission capacity and no geographical infl uence.It can provide ubiquitous internet access services for users all over the world.However,the heterogeneity of satellite internet and ground network,the channel opening and node exposure of satellite internet will pose a security threat to network access and resource management.Aiming at the security problem of satellite internet,a multilayer satellite internet security management architecture based on blockchain was proposed.As a distributed ledger technology,blockchain uses chain data structure to verify and store data,and adopts encryption methods to maintain that data blocks cannot be tampered.Blockchain can realize network security access,trusted resource management,and provide information security protection for satellite internet.This paper improved the security of satellite internet by integrating blockchain technology with satellite internet.
