Abstract：Facing the threats of high mutation and diversifed propagation of ransomware in smartcampuses，traditional boundaryprotection mechanisms struggle tocounter dynamic attcks due tofawslike static permision managementnd single authentication.Basedonthezerotrustprincipleof“never trust，always verify”，thisresearchdesignsaherarchicaldyamic defense system against ransomware insmart campuses.The proposed architecture integrates mult-level protection spaning from physicallayer toapplication layer，withcore modules includingdynamicaccesscontrol，continuous trust evaluation，and policyoptimization.Experimentalsimulationsofransomwareatackscenariosvalidate thesystem'sefectivenessinkeymetrics suchasblockingrate，falsepositiverate，ndresponsetime.Theresearchdemonstratesthatthissystemsignificantlyenhancesthe campus network'sdynamicdefensecapabiltiesagainstransomware，providing practicalreferences forimplementing zero trust architecture in educational fields.
