摘　　要：现有的航空自组网密钥管理方案因严重依赖可信中心或基础设施,存在密钥管理效率不高、密钥安全性较低等问题。为实现航空自组网场景中,飞机节点之间在高速动态的无线电通信链路的安全信息通信,提出了一种基于区块链的航空自组网的密钥管理方案。所提方案可以通过使用密钥加密技术和改进的密钥协商协议进行密钥对的安全生成和分发,保证密钥管理的安全性和灵活性。同时通过区块链的智能合约,实现公钥数据的验证和添加,以及自动化地公钥存储和撤销操作,提高密钥管理的效率和公平性。性能评估表明,所提方案在通信消耗和成本开销等方面均优于传统的航空自组网密钥管理方案。The existing aeronautical ad hoc network key management scheme relies heavily on trusted centers or infrastructure,resulting in low key management efficiency and low key security.In order to realize the secure information communication between aircraft nodes in high-speed dynamic radio communication links in aviation ad hoc network scenarios,a key management scheme based on blockchain aeronautical ad hoc network is proposed.The proposed scheme can be ensured the security and flexibility of key management by using key cryptography technology and improved key agreement protocol for secure generation and distribution of key pairs.Meanwhile,the verification and addition of public key data,as well as automatic public key storage and revocation operations can be achieved through the smart contract of the blockchain,so as to improve the efficiency and fairness of key management.The performance evaluation results that the proposed scheme is superior to the traditional aeronautical ad hoc network key management scheme in terms of communication consumption and computing consumption.
