Trusted　requirements　affect　the　trusted　attributes　of　software,　and　have　an　important　impact　on　whether　trusted　software　can　meet　the　trusted　requirements.　However,　despite　the　continuous　development　of　society　and　technology,　the　work　of　obtaining　and　analyzing　trusted　requirements　has　not　become　easy,　has　become　more　and　more　difficult.　In　the　process　of　obtaining　trusted　requirements,　a　series　of　problems,　such　as　low　efficiency　and　inaccurate　acquisition　of　requirements,　serious　software　quality　problems,　budget　overruns　and　delivery　delays,　have　become　increasingly　prominent.　In　view　of　the　above　problems,　this　paper　integrates　the　concept　of　meta-requirement　into　trusted　requirement.　Based　on　the　respective　characteristics　of　meta-requirement　and　trusted　requirement,　this　paper　puts　forward　the　concept　of　trusted　meta-requirement,　and　introduces　the　basic　elements　and　characteristics.　Then　the　trusted　meta-requirements　and　some　rules　involved　in　it　are　formalized　by　the　combination　of　first-order　logic　and　set　theory　in　order　to　improve　the　accuracy　of　the　description　and　analysis　of　trusted　requirements.　©　2022　IEEE.
