Ngaba i-Schneier Method iyindlela enhle yokucima idatha?
Indlela yeSchneier yindlela yokwenza i- sanitization yedatha esekelwe kwisofthiwe esetyenziswe kwezinye iifayile ze-shredder kunye nedatha yokutshatyalaliswa kwedatha ukubhala ulwazi olukhoyo kwi- hard drive okanye kwezinye izixhobo zokugcina.
Ukutshabalalisa i-hard drive usebenzisa indlela yokuchithwa kwe-data ye-Schneier izakukhusela zonke iinkqubo zokubuyisela iifayile ezisekelwe kwi-software ekufumaneni ulwazi kwi-drive kwaye inokuthi ithintele iindlela ezininzi zokubuyisela kwi-hardware ukususela ngolwazi.
Ngendlela emfutshane, indlela yeSchneier ibhala ngaphezulu kwedatha kwisitoreji sokugcina kunye enye, ize ibe yinto, kwaye ekugqibeleni ihamba ngeendidi ezininzi ezingabonakaliyo. Kukho iinkcukacha ngezantsi apha, kunye nemizekelo embalwa yeenkqubo eziquka indlela yeSchneier njengendlela yokukhetha xa ususa idatha.
Yenzani i-Schneier Indlela?
Zonke iinkqubo zokuhlanjululwa kwedata zisebenza ngendlela efanayo kodwa azihlali ziqhutyelwa ngendlela efanayo. Umzekelo, indlela yokubhala i-Zero igqithisa idatha ngeefer kuphela. Abanye, njengeDatha yeDatha , sebenzisa kuphela abalinganiswa abangahleliyo. I-HMG IS5 iyafana kakhulu ukuba ibhala i-zero, ibe enye, kwaye isalathisi esingenangqungquthela, kodwa isithuba esisodwa se-character character.
Nangona kunjalo, ngeendlela zeSchneier, kukho ukudibanisa kweendwendwe ezininzi zeenhlamvu ezingafaniyo kunye neeferos kunye nazo. Le yindlela eqhelekileyo yokuphunyezwa ngayo:
- Ukupasa 1: Ubhala enye
- Ukupasa 2: Ubhala i-zero
- Ukupasa 3: Ubhala umlambo wabalinganiswa abangenanto
- Ukupasa 4: Ubhala umlambo wabalinganiswa abangenanto
- Ukupasa 5: Ubhala umlambo wabalinganiswa abangenanto
- Ukupasa 6: Ubhala umlambo wabalinganiswa abangenanto
- Umdluli wesi-7: Ubhala umlambo wabalinganiswa abangenanto
Ezinye iinkqubo zingasebenzisa indlela yeSchneier ngeentlobo ezincinane. Ngokomzekelo, ezinye izicelo zingaxhasa ukuqinisekiswa emva kokupasa kokuqala okanye kokugqibela. Oko kuyenzayo kuqinisekisa ukuba umlingiswa, njengomnye umlinganisi okanye ongenangqungquthela, wabhalwa ngokufanelekileyo kwi-drive. Ukuba kwakungenjalo, isofthiwe ingakuxelela okanye iqalise ngokutsha ngokuzenzekelayo kwaye iqhube ngokupasa kwakhona.
Iphulo: Kukho iinkqubo ezikuvumela ukuba ulungelelanise ukupasa, njengokwenza i-zero eyongezelelweyo ebhale emva kokuPhepha 2. Nangona kunjalo, ukuba wenze utshintsho olwaneleyo kwindlela yeSchneier, akuyi kuhlala loo ndlela. Ngokomzekelo, ukuba ususile iipaseli zokuqala ezimbini kwaye wongeza ezinye iidrafti zezinye iziganeko ezikhethiweyo, uya kuba nokwakha indlela yeGutmann .
Iinkqubo ezixhasa iSchneier
Iinkqubo ezininzi ezahlukeneyo maye usebenzise indlela yeSchneier yokucima idatha. Imizekelo embalwa yi- Eraser , iFree File Shredder , i- CBL Data Shredder , i-CyberShredder, i-Delete Files ngokungapheliyo, kunye ne-Free EASIS Data Eraser.
Nangona kunjalo, njengoko sitshilo ngasentla, ezinye iifayile zefayile kunye neenkqubo zokubhubhisa idatha zivumela ukuba wenze ngokwezifiso izinto eziqhubekayo ngexesha lokupasa. Oku kuthetha ukuba nangona bengenayo le ndlela ikhona, unako "ukwakha" indlela yeSchneier kulezo nkqubo usebenzisa isakhiwo esivela ngasentla.
Uninzi lwenkqubo yokubhubhisa idatha luxhasa iindlela ezininzi zokuncedisa ukuhlanjululwa kwedatha kwongezwa kwindlela yeSchneier. Ukuba ufuna, unako ukukhetha indlela eyahlukileyo yokuchithwa kwedatha xa unenkqubo evulekile.
