Nguwuphi umsebenzi we-Masking we-compy of myling yenethiwekhi yenethiwekhi?

Imaski yedatha kwi-packet yenethiwekhi yenethiwekhi (i-NPB) ibhekisa kwinkqubo yokutshintsha okanye yokususa idatha ebuthathaka kwi-Traine yenethiwekhi njengoko idlula kwisixhobo. Injongo yokufumana imaski yedatha kukukhusela idatha ebuthathaka ekubeni ivezwe kumaqela angagunyaziswanga ngelixa uvumela itrafikhi yenethiwekhi yokuqesha kakuhle.

Kutheni ufuna imaski yedatha?

Kuba, ukuguqula idatha "kwimeko yedatha yokhuseleko lwabathengi okanye idatha enobuthathaka kwezorhwebo", cela idatha esifuna ukuyitshintsha ihambelana nokukhuseleka komsebenzisi okanye kwidatha yeshishini. Ukugcina idatha kukufihla idatha enjalo ukuthintela ukuvuza.

Kwinqanaba lokufumana imaski yedatha, ethetha ngokubanzi, okoko ulwazi lwantlandlolo alunakukhutshwa, aluyi kubangela ukuba ulwazi lokuvuza. Ukuba uguqulwe kakhulu, kulula ukuphulukana neempawu zokuqala zedatha. Ke ngoko, kowona msebenzi wokwenyani, kufuneka ukhethe imithetho efanelekileyo yonxibelelaniso ngokwesimo sezulu. Guqula igama, inombolo ye-ID, idilesi, inombolo yefowuni, inombolo yefowuni kunye namanye amabala ahambelana nabathengi.

Kukho iindlela ezahlukeneyo zobuchule ezinokusetyenziselwa imaski yedatha kwi-NPB, kubandakanya:

1. UkuphuculwaOku kubandakanya ukutshintsha idatha ebuthathaka ngethokheni okanye ixabiso lendawo engenantsingiselo ngaphandle komxholo wendlela yenethiwekhi. Umzekelo, inombolo yekhadi letyala inokutshintshwa ngesazisi esahlukileyo esinxulunyaniswa nenombolo yekhadi kwi-NPB.

2. EncryptionOku kubandakanya ukukrazula idatha ebuthathaka usebenzisa i-algorithm encryption algorithm, ukuze ingafundwa ngamaqela angagunyaziswanga. Idatha efihliweyo inokuthi emva koko ithunyelwe ngenethiwekhi njengento eqhelekileyo kwaye ihlawulwe i-therfit ngamaqela agunyazisiweyo kwelinye icala.

3. I-PseundenymisoryOku kubandakanya ukutshintsha idatha ebuthathaka ngesantya esahlukileyo, kodwa isayekele ixabiso. Umzekelo, igama lomntu linokutshintshwa kunye nomtya ongahleliyo wabalinganiswa osahlukileyo kuloo mntu.

4. Kwakhona: Oku kubandakanya ukususa ngokupheleleyo idatha ebuthathaka evela kwitrafikhi yenethiwekhi. Oku kunokuba yindlela eluncedo xa idatha ayifuneki kwinjongo ekujongwe ukuba itrafikhi kunye nobukho bayo buya kwandisa umngcipheko wokophula idatha.

 

 

Umthengisi we-Rect yeNethiwekhi yeNethiwekhi yeNethiwekhi (i-NPB) unokuxhasa:

UkuphuculwaOku kubandakanya ukutshintsha idatha ebuthathaka ngethokheni okanye ixabiso lendawo engenantsingiselo ngaphandle komxholo wendlela yenethiwekhi. Umzekelo, inombolo yekhadi letyala inokutshintshwa ngesazisi esahlukileyo esinxulunyaniswa nenombolo yekhadi kwi-NPB.

I-PseundenymisoryOku kubandakanya ukutshintsha idatha ebuthathaka ngesantya esahlukileyo, kodwa isayekele ixabiso. Umzekelo, igama lomntu linokutshintshwa kunye nomtya ongahleliyo wabalinganiswa osahlukileyo kuloo mntu.

Ingathatha indawo nayiphi na imimandla ephambili kwidatha yoqobo esekwe kwinqanaba lenqanaba lomgaqo-nkqubo ukulungiselela ulwazi olunobuthathaka. Unokuphumeza imigaqo-nkqubo yokuphuma kwetrafiki ngokusekwe kulawulo lomsebenzisi.

I-Conlical Packer Packer yeNethiwekhi yeNethiwekhi (i-NPB) "I-Tonet yeMaski yeTrafikhi yeTrafiki", ikwabizwa ngokuba yidatha engaziwa yenethiwekhi, yinkqubo yokufihla ulwazi olunobuthathaka okanye lwe-pii) kwi-traffic. Oku kungenziwa kwi-Mylling Packer Procker Procker (i-NPB) ngokumisela ifowuni ukuba icoce kwaye iguqule ithrafikhi njengoko idlula.

 

Ngaphambi kokuba imaski yedatha:

 

Emva kokuba imaski yedatha:

 

Nanga amanyathelo aqhelekileyo ukwenza imaski yenethiwekhi kwi-packet yenethiwekhi:

1) Chonga idatha enobuthathaka okanye ye-pii efuna ukuba imaski. Oku kunokubandakanya izinto ezinje ngenombolo yekhadi letyala, iinombolo zoKhuseleko lweNtlalo, okanye ezinye iinkcukacha zobuqu.

2) Qwalasela i-NPB ukuchonga itrafikhi equlethe idatha ebuthathaka usebenzisa ubuchule bokucoca obuqhelekileyo. Oku kunokwenziwa kusetyenziswa amabinzana okanye ezinye iindlela zokulinganisa.

3) Nje ukuba itrafikhi ichongiwe, cwangcisa i-NPB kwi-Mask idatha ebuthathaka. Oku kungenziwa ngokutshintsha idatha ngeyona datha ngexabiso elingaqhelekanga okanye elenzelwe umxholo, okanye ngokususa idatha ngokupheleleyo.

4) Vavanya ubumbeko lokuqinisekisa ukuba idatha ebuthathaka ifihlakele ngokufanelekileyo kwaye ukuba ithuthuthu laseNethiwekhi lisahamba kakuhle.

5) Ukubeka iliso kwi-NPB ukuqinisekisa ukuba imaski isetyenziswa ngokuchanekileyo kwaye akukho micimbi yokusebenza okanye ezinye iingxaki.

 

Ngokubanzi, imephu yedatha yenethiwekhi linyathelo elibalulekileyo ekuqinisekiseni ukuba yimfihlo kunye nokhuseleko lolwazi olunobuthathaka kwinethiwekhi. Ngokumisela umthengisi wepakethi yenethiwekhi ukwenza lo msebenzi, imibutho inokunciphisa umngcipheko wokuqhekeka kwedatha okanye ezinye iziganeko zezokhuseleko.
