Ukubunjwa kweenkwenkwezi

UZhi Zhang et al.ukusuka kwiSikolo soNxibelelwano kunye nobuNjineli boLwazi, iYunivesithi yeSayensi ye-Electronic kunye neTekhnoloji yaseChina yenzelwe i-constellation Reshaping chaotic encryption (CSCEn) iskimu esinokuhanjiswa kweenkcukacha-manani ezilawulekayo, njengoko kubonisiwe kwi-FIG.2. Okokuqala, i-orthogonal amplitude modulation (QAM) iisimboli zolandelelwano zahlulwe zaba zilandelelanisi ezininzi, kwaye ukubunjwa okunokwenzeka (PS) kwenziwa ngokusekelwe kulwazi lweenkcukacha-manani (SI) (ngokutshintshwa kwendawo yeenkwenkwezi).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 nje ukuqonda ukuhanjiswa okuguquguqukayo kunye nobunzima obuphantsi kunye nokuphucula ukusebenza kokuthumela kunye nokufumana imiqondiso, kodwa kwakhona ukubonelela ngokhuseleko olwaneleyo ukuxhathisa uhlaselo oluvela kwiyunithi yenethiwekhi ye-optical network (ONU), ngokungathandabuzekiyo iya kuba nethemba elihle lesicelo kwi kwixesha elizayo.
