Ukubunjwa kweenkwenkwezi

UZhi Zhang et al.ukusuka kwiSikolo soNxibelelwano kunye nobuNjineli boLwazi, iYunivesithi yeSayensi ye-Electronic kunye neTeknoloji yaseChina yenzelwe i-constellation Reshaping chaotic encryption (CSCEn) iskimu esinokulawulwa kokusasazwa kwamanani, njengoko kubonisiwe kwi-FIG 2. Okokuqala, ulandelelwano lwesimboli ye-orthogonal amplitude (QAM) yahlulahlulwe. kulandelelwano olungaphantsi oluliqela, kunye nokubunjwa okunokwenzeka (PS) kwenziwa ngokusekwe kulwazi lwamanani (SI) (ngokutshintshwa kommandla weenkwenkwezi).Emva koko, ulandelelwano lwe-SI lufakwe ngekhowudi kwaye lufihliweyo kwizigaba zomqondiso wesiphithiphithi kusetyenziswa i-algorithm engundoqo yokusabalalisa.I-SI ikhutshwe ekupheleni kokufumana kwakhona umqondiso wokuqala [2].Abaphandi bahambisa ngempumelelo i-encrypted ps-16-qam isignali phezu kwefayibha yemowudi enye (SSMF) ye-25km.Ngenxa yokuba esi sikimu asikwazi ukuqonda kuphela ukuhanjiswa okuguquguqukayo kunye nobunzima obuphantsi kunye nokuphucula ukusebenza kokuthumela nokufumana iimpawu, kodwa nokubonelela ngokhuseleko olwaneleyo ukuxhathisa ukuhlaselwa kweyunithi yenethiwekhi ye-optical engekho mthethweni (I-ONU), ngokungathandabuzekiyo iya kuba nethemba elihle lesicelo kwixesha elizayo.
