Abstract: The application of unmanned aerial vehicles(UAVs) in disaster relief,logistics distribution,power inspection and other fields is becoming increasingly widespread,and their network security communication issues are becoming more prominent.A secure and efficient key management scheme is necessary for ensuring the secure communication of UAV networks.A key management scheme for UAV networks based on LKH and Blom is proposed.By constructing an adaptive LKH structure and optimizing the key management algorithm,efficient key distribution and management are achieved,enhancing the security and flexibility of UAV network communication.The scheme innovatively integrates the Blom key pre-distribution mechanism to improve system invulnerability and node connectivity efficiency.The key management structure,key pre-distribution protocol,member communication process,and key update protocol of the scheme are introduced in detail,and the efficiency and security of the scheme are analyzed,providing a new approach and method for key management in unmanned aerial vehicle networks.Theoretical analysis and performance testing show that this scheme can effectively reduce key management overhead while ensuring system security,and has certain practical application value.

Key words: LKH, Blom, Unmanned aerial vehicle network, Key management
