Ikimenyetso cy'inyenyeri

Zhi Zhang n'abandi. kuva mu Ishuri Rikuru ry’itumanaho n’ikoranabuhanga, kaminuza y’ubumenyi n’ikoranabuhanga mu Bushinwa yateguye inyenyeri yitwa Reshaping chaotic encryption (CSCEn) ifite gahunda yo gukwirakwiza imibare igenzurwa, nkuko bigaragara muri FIG 2. Ubwa mbere, ibimenyetso bya orthogonal amplitude modulation (QAM) bikurikirana byagabanijwe muburyo butandukanye, kandi gushiraho (PS) byakozwe hashingiwe ku makuru y'ibarurishamibare (SI) (binyuze mu gusimbuza akarere k’inyenyeri). Hanyuma, urutonde rwa SI rwashizwemo kandi rushyirwa mubice byerekana akaduruvayo hakoreshejwe urufunguzo rwo gukwirakwiza algorithm. SI yakuwe kumpera yakira kugirango igarure ibimenyetso byumwimerere [2]. Abashakashatsi bohereje neza ibimenyetso byabitswe ps-16-qam hejuru ya fibre isanzwe imwe (SSMF) ya 25km. Kuberako iyi gahunda idashobora gusa kubona uburyo bworoshye bwoherezwa hamwe no kugorana no kunoza imikorere yo kohereza no kwakira ibimenyetso, ariko kandi bitanga umutekano uhagije wo kurwanya igitero kiva mumashanyarazi atemewe (ONU), nta gushidikanya bizagira ibyifuzo byiza byo gusaba ejo hazaza.
