In　order　to　solve　the　communication　security　problem　between　clusters　and　clusters.　This　paper　proposes　a　data-trusted　transmission　mechanism　based　on　Merkle　authentication,　which　guarantees　the　correctness,　integrity,　confidentiality　and　reliability　of　intra-cluster　transmission　and　inter-cluster　transmission　messages.　It　can　resist　security　problems　such　as　forgery　attacks　and　anti-replay　attacks　to　a　certain　degree.　The　method　adopts　a　hierarchical　multipath　routing　scheme　based　on　Merkle　tree　authentication.　The　hierarchical　multipath　routing　scheme　routes　data　by　using　multiple　paths,　can　bypass　malicious　nodes　to　a　certain　extent,　improve　the　reliability　of　the　network,　and　even　if　the　malicious　node　intercepts　the　data,　it　cannot　know　the　complete　information　of　the　data.　©　2022　IEEE.
