The　current　deep　integration　of　the　Internet　of　Things　and　edge　computing　has　improved　the　computing　capabilities　of　the　perception　layer　of　the　Internet　of　Things.　The　existing　edge　computing　offloading　technology　has　the　problems　of　lack　of　a　security　authentication　mechanism　and　a　single　problem　of　solidification　of　offloading　strategies.　Based　on　this,　this　paper　studies　the　trusted　authentication　mechanism　for　the　Internet　of　Things　and　the　optimization　scheme　of　computing　offloading.　While　ensuring　the　network　security　of　the　perception　layer　of　the　Internet　of　Things,　according　to　the　changes　of　the　perception　layer　network,　adaptively　adjust　the　computing　task　offloading　strategy　for　the　Internet　of　Things　terminal　to　improve　the　operating　efficiency　of　the　perception　layer　of　the　Internet　of　Things.　©　2022　ACM.
