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 zahlulahlulwe zaba zilandelelanisi ezininzi, kwaye ukubunjwa okunokwenzeka (PS) kwenziwa ngokusekelwe kulwazi lweenkcukacha-manani (SI) (ngokutshintshwa kwendawo yeenkwenkwezi). Emva koko, ulandelelwano lwe-SI lufakwe ngekhowudi kwaye lufihliwe kwizigaba zeempawu zesiphithiphithi kusetyenziswa i-algorithm yokusabalalisa okungundoqo. I-SI ikhutshwe ekupheleni kokufumana kwakhona umqondiso wokuqala [2]. Abaphandi badlulisela 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 nokufumana iimpawu, kodwa kwakhona ukubonelela ngokhuseleko olwaneleyo ukuxhathisa ukuhlaselwa kweyunithi yenethiwekhi ye-optical network (I-ONU), ngokungathandabuzekiyo iya kuba nethemba elihle lesicelo kwixesha elizayo.
