As　a　new　type　of　network　model,　edge　computing　has　strong　computing　offload　ability,　which　can　effectively　alleviate　the　burden　of　cloud　center　and　network　communication,　match　the　urgent　demand　of　accelerating　wireless　terminals　operational　capabilities,　and　obtain　rapid　development　and　application.　However,　the　existing　edge　computing　authentication　methods　are　mainly　based　on　traditional　identity　authentication,　which　is　difficult　to　prevent　the　network　access　of　untrusted　wireless　terminals.　Based　on　the　above,　this　paper　proposes　a　trusted　connection　architecture　TCA-EC　for　edge　computing,　which　is　based　on　the　trusted　connection　architecture　TCA.　The　architecture　realizes　two-way　identity　authentication,　two-way　platform　integrity　authentication　and　two-way　behavior　trusted　authentication　between　MEC　server　and　wireless　terminal,　and　ensures　the　security　of　edge　computing.　©　2021　IEEE.
