At　present,　when　smart　electricity　terminals　request　access　to　the　edge　computing　network,　it　often　directly　uses　the　traditional　access　authentication　method.　In　contrast,　it　is　challenging　to　prevent　the　malicious　access　of　untrusted　electricity　IoT　terminals.　This　paper　proposed　a　trusted　connection　architecture　and　authentication　protocol　for　the　electric　IoT　that　realizes　two-way　identity　authentication　and　platform　integrity　authentication　between　the　electric　IoT　terminal　and　the　electricity　edge　gateway.　©　2022　ACM.
