Umahluko phakathi kweNdlela kaGutmann kunye nezinye iindlela zokucoca

Makhe sijonge ezi ndlela zilandelayo zokucima eqhelekileyo ehlabathini, yaye ngaloo ndlela ukwazi ukubona umahluko phakathi ngamnye kubo ngokuthelekisa kubo indlela Gutmann.

Indlela yeSebe lezoKhuselo laseUnited States, iDoD 5220.22-M: Ngomnye weyona migangatho iphuculweyo, ekhuselekileyo kunye neqhelekileyo yokucima ephunyezwa phakathi kwe-3 yokupasa kunye ne-7 yokupasa ngeendlela ezahlukeneyo zokujonga.

Indlela yoMkhosi waseUnited States, AR 380-19: Le ndlela ichazwa kwaye ipapashwe nguMkhosi wase-United States kwi-Army Regulation 380-19. Ukonakalisa idatha kwi-3 yokupasa.

Indlela yoMkhosi woMoya waseUnited States, AFSSI-5020: Le ndlela isebenzisa ooziro, abo, kunye nexabiso lepseudorandom, kodwa ngolandelelwano olwahlukileyo kunye nenani lokudlula.

I-Canadian RCMP TSSIT OPS-II Indlela: Isebenzisa ukupasa oku-6 okuphindaphindayo okuhambelanayo kwaye igqibezele ukubhala ngaphezulu komlingiswa we-pseudorandom kunye nokuqinisekiswa kokupasa kwe-XNUMX.

Indlela yaseBritani HMG IS5: Isebenzisa i-2 idlula okanye i-3 idlula apho ibhala indibaniselwano ye-zero, enye, kunye nedatha engahleliweyo kunye nokuqinisekiswa.

Indlela kaPeter Gutmann: Eyona ndlela ikhuselekileyo yokucoca. Isebenza ngokubhala ngaphezulu amaxabiso angama-pseudo-random amaxesha angama-35. Ukucoca kukaGutmann kusebenzisa amaxabiso angenamkhethe okokuqala nowokugqibela ukupasa oku-4, emva koko ipateni entsonkothileyo ukusuka kwi-5 ukuya kwe-31.

Xa ufuna ukucima idiski nge Gutmann disk indlela yokucima, kufuneka ukhethe ekhuselekileyo nethembekileyo indlela yesoftware kaGutmann ukukunceda.

Uninzi lwesoftware enendlela yeGutmann njengenye yemisebenzi yayo ayisebenzi nje ukucima iidiski ngokulula, kodwa nokucima izahlulelo kunye nezithuba ezingabiwanga.

• Vumela isoftware yenze ukucima. Eli nyathelo lingathatha ixesha elide, kuxhomekeke kubukhulu be-hard drive.

Indlela yeGutmann ithatha ixesha elingakanani ukuCoca?

Kufuneka kuqikelelwe ngokobungakanani beyunithi, umzekelo, iyunithi ye-1 TB Kungathatha malunga neeyure ezili-10 ukucima. Le yenye yezinto ezingalunganga ezicacileyo.

Nangona kunjalo, Indlela kaGutmann Kuthatha ixesha elide ukwenza ucimo, ngenxa yokuba lwenziwa ngamapasi angama-35. Oku kuqinisekisa ukuba idatha icinyiweyo ayinakufunyanwa ngayo nayiphi na indlela.

Nje ukuba indawo yedisk ibhalwe ngaphezulu ngokusula kukaGutmann, akukho ndlela yaziwayo yokusebenzisa isoftware ukuyibuyisela kwakhona. Ayinakwenziwa ngesoftware yodwa, njengoko isixhobo sokugcina sibuyisela imixholo yayo yangoku ngojongano lwayo oluqhelekileyo.
