Quantum　key　agreement　(QKA)　permits　participants　to　constitute　a　shared　key　on　a　quantum　channel,　and　no　participants　are　able　to　independently　determine　the　shared　key.　In　fact,　particles　are　frequently　affected　by　channel　noise　in　the　transmission　process　of　quantum　channel.　Under　the　cover　of　noise,　attackers　can　launch　malicious　attacks.　In　this　thesis,　on　account　of　the　usage　of　entanglement　swapping　of　GHZ　state　and　logical　Bell　states,　we　design　two　two-party　QKA　protocols　which　are　immune　to　collective-dephasing　noise　and　collective-rotation　noise,　respectively.　In　comparison　with　the　existing　QKA　protocols　of　two　parties,　the　proposed　protocols　have　better　quantum　resource　cost　and　the　qubit　efficiency　in　the　global　scope.　Security　analysis　reveals　that　they　can　resist　not　only　attacks　by　participants　but　also　external　attacks.
