Kev tshuaj xyuas ntawm ib lab nyiaj tau txais los ntawm ntau tus neeg siv cov ntaub ntawv xau

Tshaj tawm Cov txheeb cais tsim tawm raws li kev txheeb xyuas ntawm kev sau ntawm ib lab nyiaj tau txais los ntawm ntau yam ntaub ntawv xau nrog kev lees paub tsis raug. Kuj npaj cov qauv nrog cov ntaub ntawv ntawm qhov zaus ntawm kev siv cov passwords raug thiab cov lis los ntawm 1 txhiab, 10, 100 txhiab, 1 lab thiab 10 lab tus password nrov tshaj plaws, uas tuaj yeem siv los txhawm rau txhawm rau xaiv tus password hashes.

Qee qhov generalization thiab kev tshawb pom:

• Ntawm qhov tshwm sim ntawm cov ntaub ntawv ntau txhiab lab, 257 lab tau muab pov tseg raws li cov ntaub ntawv tsis raug (cov ntaub ntawv chaotic nyob rau hauv cov ntaub ntawv tsis raug) lossis cov nyiaj xeem. Tom qab tag nrho cov kev lim dej, 169 lab tus passwords thiab 293 lab tus lej nkag tau raug txheeb xyuas los ntawm ntau lab cov ntaub ntawv.
• Tus password nrov tshaj plaws "123456" yog siv li ntawm 7 lab lub sijhawm (0.722% ntawm tag nrho cov passwords). Ntxiv nrog rau qhov pom kev lag luam ua raws passwords 123456789, password, qwerty, 12345678.
• Qhov sib koom ntawm ntau txhiab tus passwords nrov tshaj plaws yog 6.607% ntawm tag nrho cov passwords, feem ntawm lab tus passwords nrov tshaj plaws yog 36.28%, thiab feem ntawm 10 lab yog 54%.
• Qhov nruab nrab lo lus zais loj yog 9.4822 cim.
• 12.04% ntawm cov passwords muaj cov cim tshwj xeeb.
• 28.79% ntawm cov passwords muaj cov tsiaj ntawv nkaus xwb.
• 26.16% ntawm cov passwords suav nrog tsuas yog cov cim qis.
• 13.37% ntawm cov passwords tsuas muaj cov lej xwb.
• 34.41% ntawm cov passwords xaus nrog cov lej, tab sis tsuas yog 4.522% ntawm tag nrho cov passwords pib nrog tus lej.
• Tsuas yog 8.83% ntawm tus password yog qhov tshwj xeeb, qhov seem tshwm sim ob lossis ntau zaus. Qhov nruab nrab ntev ntawm tus password tshwj xeeb yog 9.7965 cim.

• Tsau kev nrhiav neeg ua haujlwm ntawm high-quality, high-entropy passwords uas zoo sib xws nyob rau hauv style (10 cim, random ua ke ntawm cov zauv, cov tsiaj ntawv loj thiab qis, tsis muaj cov cim tshwj xeeb, cov tsiaj ntawv loj thaum pib thiab xaus) thiab rov siv dua. Tus nqi rov qab siv tau tsawg heev (qee qhov ntawm cov passwords no tau rov ua dua 10 zaug), tab sis tseem siab dua qhov xav tau rau cov passwords ntawm qib no.
