摘　　要：为解决现有分层无人机(UAV)网络中群组密钥管理存在的单点故障问题,群组成员离线导致整个群组无法计算、及时更新组密钥的问题,该文提出一种支持异步计算的去中心群组密钥管理方案。该方案采用异步棘轮树(ART)协议实现对群组密钥的预部署,各成员能对组密钥进行异步计算、自主更新;利用区块链技术的去中心化特性解决了单点故障问题,提高了群组密钥管理的透明性与公平性。性能评估表明,与同类方案相比,该方案中的簇成员无人机具有较低的计算开销和通信开销,适合应用于分层无人机网络环境。To address the single point failure of group key management in the existing hierarchical Unmanned Aerial Vehicle(UAV)network,and the incapability of timely group key calculation and update caused by offline group members,a decentralized group key management scheme that supports asynchronous computing is proposed.The Asynchronous Ratchet Tree(ART)protocol is adopted to realize the pre-deployment of the group key,in which asynchronous calculation and autonomous update of the group key can be performed by each member.The decentralization feature of the blockchain technology is employed to solve the single point failure problem,which improves the transparency and fairness of group key management.The performance evaluation shows that,compared with existing schemes,the cluster member UAV in this scheme has lower computational overhead and communication overhead,and are suitable for application in a hierarchical UAV network environment.
