Hagati ya Pattern, PIN na Password ni iki gitanga umutekano kurusha ibindi?

... by alainmat in Tech News 630

Telephone zacu ziba zibitse amabanga menshi ndetse na byinshi bijyanye n'ubuzima bwacu bwite tuba tudakeneye ko byabonwa na buriwese, bityo tugashaka uburyo buboneye bwo kurinda umutekano wazo. Mu buryo bukoreshwa cyane harimo password, PIN ndetse na pattern; tukaba tugiye kurebera hamwe igifite umutekano usumba uw'ibindi bityo nujya guhitamo icyo ukoresha ujye uba uzi ingano y'umutekano ugiye guha telephone yawe.

1. Pattern

Pattern ni uburyo bukoresha utudomo ugenda uhuza ugashushanya icyo ushaka ko kizakubera urufunguzo rukwinjiza mu bibitse muri telephone yawe. Patterns nyinshi ziba zigizwe n'utudomo icyenda(9) ushobora kugenda uhuza kugeza ukoze urufunguzo wifuza, gusa kuri pattern ntabwo bishoboka gukoresha akadomo inshuro irenze imwe ni ukuvuga ngo niba ko kadomo wagakoresheje ibyako byarangiye. 


Reka noneho turebe umubare w'uburyo bwose bushoboka kuri pattern. Iyo utangira uba ufite amahitamo 9 y'aho watangirira. Iyo umaze guhitamo akadomo utangiriraho ubwo ako kaba kavuyemo ugasigarana utudomo 8 wakomerezaho. Wahitamo akadomo ka kabiri ubwo nabwo birumvikana ko uba usigaranye utudomo 7 wahitamo nanone, gutyo gutyo mpaka utudomo dushize. Ubwo iyo ukubye ayo mahitamo yose ubona ko amahitamo abaho ahoboka ari 632,880 (9*8*7*6*5*4*3*2*1 = 632,880) (abazi imibare yihuta bigaragara ko ari factorial ya 9 ingana na 632,880). Ayo mahitamo yose ni mu gihe wakoresheje utudomo twose muri pattern yawe. Uko ukoresha utudomo duke, ni nako uburyo bushoboka bugabanuka. Urugero niba wakoresheje utudomo 5 gusa ubwo ufite amahitamo 9*8*7*6*5 = 15,120.


2. PIN

PIN(Personal Identification Number) ni uburyo bukoresha imibare, iyo mibare wahisemo ikakubera urufunguzo. Nk'uko twese tubizi imibare wakoresha ni icumi(0, 1, 2, 3, 4, 5, 6, 7, 8, 9). Kuri PIN ho wemerewe gukoresha umubare uwo ariwo wose inshuro zirenze imwe bityo bigatuma umubare w'amahitamo ashoboka wiyongera. Abenshi bakoresha PIN bashyiramo imibare 4 ariko burya ishobora kugeza kuri 16, ubwo bivuze ko buri mubare uba ushobora kuwukoresha inshuro 16.


Aha naho reka tubare turebe amahitamo yose ubasha guhitamo. Kuva buri mubare wawukoresha inshuro 16 ubwo nidukuba kuri buri mubare turabona uburyo 1,099,511,627,776(16*16*16*16*16*16*16*16*16*16 = 1,099,511,627,776 cyangwa 16^10=1,099,511,627,776) bushoboka. Bigaragara ko uriya mubare ari munini bishoboka bityo ukaba ufite amahitamo menshi ahoboka. Reka dufate urugero nk'uko twabigenje kuri pattern, tuvuge ko wenda ushaka gukoresha PIN igizwe n'imibare 5 ubwo uzaba ufite amahitamo angana na 16*16*16*16*16 = 1,048,576.

3. Password

Password ni ubundi buryo bw'umutekano bwo bukoresha inyuguti, imibare ndetse n'ibimenyetso. Password ishobora kujyamo inyuguti zose ni ukuvuga izanditse mu cyapa ndetse no mu mukono ibyo bamwe bita inyuguti nkuru n'intoya. Nk'uko twabonye ko imibare ikoreshwa ari 10 ariyo 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 kandi inyuguti zikorershwa akaba ari 26 kandi buri yose ikaba ishobora kwandikwa mu buryo bubiri: icyapa n'umukono(A, B, C, ..., Z na a, b, c, ..., z) ndetse n'ibimenyetso byinshi cyane bigaragara kuri keyboard yawe(!, @, #, $, % ...), ibyo byumvikanisha ingano y'uburyo bushoboka ko ari bwinshi cyane.

Reka dufate urugero nanone tuvuge ko ugiye gukora password igizwe n'ibintu 5 wifuza(inyuguti,amagambo ndetse n'ibimenyetso). Ubundi uba ufite amahitamo 90 kuri buri kamwe. Nk'uko twabibaze kuri PIN ubwo hano byumvikana ko uburyo bushoboka ari 5,904,900,000 (90*90*90*90*90 = 5,904,900,000 cyangwa 90^5 = 5,904,900,000).

Umwanzuro

Mu gihe ugiye guhitamo uburyo ukoresha ujye ubanza urebe ingano y'umutekano wifuza bigendeye ku buremere bw'amabanga abitse muri telephone yawe, bityo uhitemo ubukunogeye.
Pattern ziroroha kuzibuka kandi ziranihuta kuzishushanya telephone yawe ikaba irafungutse; ibyo bikaba ari intege nke ku ruhande rw'umutekano w'ibyawe kuko byumvikana ko uramutse wegeranye n'umuntu akakureba uyishushanya byamworohera kuyisubiramo bityo akakwinjirira.
PIN zifite umutekano uruta kure uwa pattern nk'uko twabonye amahitamo uba ufite yose. Ni byiza gukora PIN izajya ikorohera kwibuka kuko bituma uyandika vuba vuba bityo n'uwaba akuri iruhande areba bikaba byamugora gufata mu mutwe imibare wanditse. Ikindi kandi ni byiza gukoresha PIN igizwe n'imibare myinshi kuko uba uzamura umutekano w'ibyawe.
Password yo niyo ifite amahitamo menshi nabyo twabibonye. Biba byiza iyo ukoze password ivangavanze ni ukuvuga irimo inyuguti nkuru n'intoya, imibare ndetse n'ibimenyetso kuko bigora undi uwo ariwe wese utari wowe waba agamije kukwinjirira. Password nizo zitanga umutekano kurusha pattern na PIN bityo nizo ukwiye gukoresha, gusa niba wahisemo PIN cyangwa pattern ukwiye guhitamo izo bitakorohera buri wese kuvumbura.


Niba wakunze iyi nkuru yisangize n'abandi. Twandikire ahagenewe kwandikwa ibitekerezo niba hari icyo wifuza kubaza cyangwa kudusangiza. Wanadukurikira kuri facebook page yacu ariyo ktimez.com
