Indlela yokufinyelela kulabo abangekho emihle kwizibalo
WPA2 , WEP , 3DES, AES, Symmetric, Asymmetric, kusho ukuthini konke, futhi kungani kufanele ukhathalele?
Yonke le migomo ihlobene nobuchwepheshe bokubethela okusetshenziselwa ukuvikela idatha yakho. Ukubethela nokubhala nge-cryptography ngokujwayelekile, kungaba izihloko ezinzima ukumboza ikhanda lakho nxazonke. Noma nini lapho ngizwa amagama algorithm e-cryptographic, ngifisa uprofesa othile we-nerdy ebhala ukulingana ebhodini, ekhuluma ngento ethile ngaye nge-Medulla Oblongata njengoba amehlo ami agqabuka ngenxa yesibindi.
Kungani kufanele ukhathalele ngokubethela?
Isizathu esiyinhloko odinga ukukhathalela mayelana nokubethela kungenxa yokuthi ngezinye izikhathi yinto eyodwa phakathi kwedatha yakho nabafana ababi. Udinga ukwazi okuyisisekelo ukuze ukwazi, noma okungenani, ukuthi idatha yakho ivikelwe kanjani ibhange lakho, umhlinzeki we-imeyli, njll. Ufuna ukuqinisekisa ukuthi awusebenzisi izinto ezingaphelelwe isikhathi abaduni abaye bawasebenzisa kakade ephukile.
Ukubethela kusetshenziswa cishe yonke indawo kuzo zonke izinhlobo zezicelo. Inhloso eyinhloko yokusebenzisa ukubethela ukuvikela imfihlo yedatha, noma ukusiza ekuvikeleni ubuqotho bomlayezo noma ifayela. Ukubethela kungasetshenziselwa kokubili idatha 'ekuhambeni', njengokuthi idluliselwa kusuka kwesistimu eyodwa kuya kwenye, noma kwedatha 'ekuphumuleni' kwiDVD, i-USB thumb drive, noma esinye isikhala sokugcina.
Ngingakunikela ngomlando wokubhala nge-cryptography futhi ngitshele ukuthi uJulius Caesar usebentisa kanjani imilayezo yokuvikela imilayezo yempi nayo yonke into enjalo, kodwa ngiyaqiniseka ukuthi kunezinye izihloko eziyizigidi ezenzelwe inetha elinganikeza ukuqonda okungaphezulu kunami anganikeza, ngakho-ke sizokweqa konke lokho.
Uma unjengami, ufuna ukuthola izandla zakho zingcolile. Nginguhlobo lokufunda olwenzayo umuntu. Ngesikhathi ngiqala ukutadisha kwami ukubethela nokubhala nge-cryptography ngaphambi kokuba ngithathe ukuhlolwa kwe-CISSP, ngangazi ukuthi ngaphandle kokuthi ngingase "ngidlale" ngokubethela, ngabe angizange ngiqonde ngempela ukuthi kwenzekani ngemuva kwesikhala lapho okuthile kubhalwe phansi noma kubonisiwe.
Angiyena isazi sezibalo, eqinisweni, ngimangalisa ngezibalo. Angizange ngikukhathalele ngempela mayelana nokulingana okuhilelekile ekuqalisweni kwemibhalo yokubhala kanye ne-whatnot, ngifuna nje ukwazi ukuthi kwenzekani kudatha uma ibhalwe ngekhodi. Ngangifuna ukuqonda imilingo ngemuva kwakho konke.
Ngakho-ke, iyiphi indlela engcono kakhulu yokufunda ngokubethela nokubhala nge-cryptography?
Ngenkathi ngifundela ukuhlolwa, ngenza uphenyo futhi ngathola ukuthi elinye lamathuluzi angcono kakhulu ongayisebenzisa ukuze uthole isipiliyoni ngezandla ngokubethela kwaba yisicelo esibizwa nge-CrypTool. I-CrypTool yasungulwa yiDeutsche Bank emuva ngo-1998 ngenzame yokuthuthukisa abasebenzi bayo ukuqonda ukuklama. Kusukela ngaleso sikhathi, i-CrypTool ishintshwe ekufakeni amathuluzi wezemfundo futhi isetshenziswe ezinye izinkampani, kanye namayunivesithi, nanoma ubani omunye ofuna ukufunda ngokubethela, ukubethelwa kwe-cryptography, ne-cryptanalysis.
I-Cryptool yokuqala, manje eyaziwa ngokuthi i-Cryptool 1 (CT1), yayisicelo se-Microsoft Windows esekelwe. Kusukela ngaleso sikhathi, kuye kwaba nezinye izinguqulo eziningana ezikhishwe njenge-Cryptool 2 (inguqulo yesimanje ye-CrypTool, i-JCrypTool (ye-Mac, Win ne-Linux), kanye nesiphequluli esisuselwe kusiphequluli esibizwa nge-CrypTool-Online.
Zonke lezi zinhlelo zokusebenza zinomgomo owodwa engqondweni: yenza ukubethelwa kokubhala okuthile okungafani nabantu abangafani namathematika njengami abangakuqonda.
Uma ukutadisha ukubethela kanye ne-cryptography namanje kuzwakala kancane kancane ngakwesibhakabhaka, ungesabi, ingxenye engcono kunoma iyiphi into ehlobene ne-crypto yincenye lapho uthola khona ukuphumula ikhodi. I-Cryptanalysis yigama eliyinkimbinkimbi yokwenza ikhodi-break, noma ukuzama ukuthola ukuthi umlayezo onqanyuliwe ungubani, ngaphandle kokuba ukhiye. Le yingxenye ejabulisayo yokutadisha zonke lezi zinto ngoba wonke umuntu uyathanda iphazili futhi ufuna ukuba ngumqaphi wezihlobo.
Abantu be-CrypTool ngisho banesayithi lokuncintisana labo abazoba yi-code-breakers okuthiwa i-MysteryTwister. Isayithi likuvumela ukuthi uzame inhlanhla yakho ngokumelene nezikhala ezidinga ipeni kanye nephepha kuphela, noma ungadlulela ezinselele eziyinkimbinkimbi ezidinga amanye amakhono okuhlela kanye namanye amandla amakhulu wekhompiyutha.
Uma ucabanga ukuthi unezinto ezithathayo, ungahlola amakhono akho ngokumelene ne "Ciphers engaphenduliwe". Lezi zicucu ziye zahlaziywa futhi zacwaningwa yizinto ezinhle kunazo zonke iminyaka futhi zingakaze ziphulwe. Uma uphazamisa enye yalezi zinsuku ungase uzitholele indawo emlandweni njengendoda noma i-gal oweqa okungaqondakali. Ubani owaziyo, ungase uzenzele umsebenzi ne-NSA.
Iphuzu liwukuthi, ukubethela akudingeki kube yisikhulu esikhulu esabekayo. Kungenxa yokuthi othile uyamangalisa ngezibalo (njengami) akusho ukuthi abakwazi ukuqonda ukubethela futhi bajabule ukufunda ngakho. Nikeza i-CrypTool ukuzama, ungaba yi-code-breaker enkulu elandelayo ngaphandle futhi ungayazi.
I-CrypTool ikhululekile futhi itholakala ku-CrypTool Portal
