I-QUMUM YOKUXELWA Ihlala ibizwa ngokuba yi-crymptography ye-cryptography, njengoko ingumzekelo owaziwayo womsebenzi wekristam ye-cryptographic.
Ngelixa kuqhubeka ukufumaneka iminyaka emininzi, inkqubela phambili iyaqhubeka ngokwenza ezi nkqubo icomboloza ngakumbi, ishiyi, kwaye ikwazi ukusebenza ngaphezulu komgama omde. Zonke ezi zibalulekile ekuthandeni ezi teknoloji ngoorhulumente kunye nomzi mveliso. Ukudityaniswa kwezi nkqubo ze-QKD kwiziseko zenethiwekhi okhoyo ngumceli mngeni wokusebenza kwabasebenzi, ababoneleli ngezibonelelo ze-fowunelwa, abasebenzi be-qokd, oonolwazi lokufumana i-qokd kunye nezazinzulu, bayasebenza kule nto.
I-QKD ibonelela ngendlela yokusasaza nokwabelana nezitshixo eziyimfihlo eziyimfuneko kwiiprotokholi ze-cryptographic. Ukubaluleka apha kukuqinisekisa ukuba bahlala ngasese, okt phakathi kwamaqela onxibelelwano. Ukwenza oku, sixhomekeke kwinto eyayibonwe njengengxaki yeenkqubo zenani; Ukuba "jonga" kubo, okanye uziphazamise nangayiphi na indlela, uqhekeza "iimpawu zexabiso.
