无人机场景下基于联盟链的KGC主密钥生成协议
KGC Master Key Generation Protocol Based on Consortium Blockchain for the UAV Scenario
摘要
Abstract
Unmanned aerial vehicles(UAVs)typically operate in open network communication environments,requiring a key generation center(KGC)to distribute key pairs to each UAV for encrypting and signing communication data.However,in traditional schemes,the master key of the KGC is held by a single third-party base station,posing significant security risks.To address the security issues of the master key in traditional KGC in this scenario,a master key generation protocol based on consortium blockchain is proposed.Instead of passively defending against malicious KGC,the protocol directly improves the KGC by introducing consortium blockchain technology.The consortium blockchain network,composed of multiple nodes,serves as the KGC,with multiple nodes jointly participating in the computation to generate the master key.If a node in the consortium blockchain refuses to participate in the computation,other nodes can collaboratively calculate the contribution value of the malicious node according to the security protocol and derive the final master key.Finally,the security properties are proven,and a real-world application scenario is simulated.The analysis and comparison of the overhead in multi-node scenarios demonstrate that the proposed scheme has low computational overhead and high availability in UAV network communication environments,eliminating the security risk of a single entity having exclusive control over the master key in traditional KGC.关键词
