摘要:

面向天地一体化信息网络等卫星资源受限和通信时延较大的场景,针对卫星通信网络中非交互式密钥交换的需求,提出一个适用于天地一体化信息网络的、基于区块链和Diffie-Hellman密钥交换协议的非交互式密钥交换方案。该方案将区块链部署在天地一体化信息网络中,组成TDYTH区块链。卫星节点完成注册后,其相关信息保存在TDYTH区块链中。当卫星节点需要与地面网络控制中心等远距离节点完成卫星组网时,双方可在非交互的条件下查询TDYTH区块链中不可篡改的信息来生成会话密钥、建立共识,进而完成接入认证和密钥分发。仿真结果表明提出的方案可满足卫星等节点的非交互式密钥分发需求,且在安全性、稳健性等方面提升显著。

Abstract:

For scenarios such as space-integrated-ground information network where satellite resources are limited and communication delays are large, in response to the requirements of non-interactive key exchange in the satellite communication network, a non-interactive key exchange scheme for space-integrated-ground information network based on blockchain and Diffi e-Hellman key exchange protocol was proposed.The scheme arranged the blockchain in space-integrated-ground information network to form TDYTH blockchain.After the satellite node was registered, its related information was stored in TDYTH blockchain.When the satellite node needed to communicated with the long-distance node such as NCC, the two parties could query the immutable information stored in TDYTH blockchain to generated the shared session key, established consensus, and then completed access authentication and key distribution under non-interactive conditions.The result of simulation demonstrated that the scheme we proposed could meet the requirements of non-interactive key distribution of satellites and other nodes, and could signifi cantly improved security and robustness.

Key words: space-integrated-ground information network, non-interactive key exchange, blockchain
