With　the　continuous　development　of　drone　remote　sensing　technology,　drone　networks　have　garnered　widespread　attention.　The　application　of　drones　has　expanded　from　military　uses　to　industrial　and　civilian　sectors,　facilitating　tasks　such　as　automated　combat,　production,　and　rescue　operations.　However,　since　drones　operate　in　public　environments,　their　communications　are　vulnerable　to　physical　attacks　and　tampering,　which　can　lead　to　privacy　leaks　and　pose　security　risks.　Additionally,　as　resource-constrained　devices,　drones　find　it　difficult　to　support　complex　encryption　algorithms.　To　address　this　issue,　this　paper　proposes　a　lightweight　authentication　protocol　based　on　Physical　Unclonable　Functions　(PUF).　This　protocol　leverages　PUF　to　prevent　physical　capture　attacks　and　enhances　system　efficiency　through　hash　and　XOR　operations.　Furthermore,　trust　management　technology　is　applied　to　further　evaluate　the　network　access　behavior　of　drones,　ensuring　trustworthy　access　to　the　drone　network.　The　security　of　this　protocol　is　verified　using　the　ROR　model　and　AVISPA　tool,　and　informal　analysis　demonstrates　that　it　meets　the　security　requirements　of　drone　networks.　Compared　with　existing　protocols,　this　protocol　shows　significant　advantages　in　terms　of　computational　and　communication　overhead,　achieving　a　good　balance　between　security　and　efficiency.　©　2024　Copyright　held　by　the　owner/author(s).　Publication　rights　licensed　to　ACM.
