Indlela yokwenza izandla kwabo bethu abangabonakali kwizibalo
I-WPA2 , i- WEP , i-3DES, i-AES, i-Symmetric, i-Asymmetric, ithetha ukuthini, kwaye kutheni unomdla?
Yonke le migaqo ihambelana nobuchwephesha bokubethela okusetyenziswa ukukhusela idatha yakho. Ukubhaliweyo kunye ne-cryptography ngokubanzi, kunokuba nzima ukuphendula intloko yakho ngeenxa zonke. Naliphi na ukuva amagama e-cryptographic algorithm, ndibonisa uprofesa othile onobhaliso obhala ukubhalisa kwibhodibhodi, edibanisa into ngaye malunga ne-Medulla Oblongata njengoko amehlo ami agubungela kwi-boredom.
Kutheni ufanele ukhathalele nge-encryption?
Isizathu esiyinhloko kufuneka uzinakekele nge-encryption kukuba ngamanye amaxesha kuphela into ephakathi kwedatha yakho kunye nabafana ababi. Kufuneka ukwazi izinto ezisiseko ukuze uza kuthi, ubuncinci, wazi ukuba idatha yakho ikhuselwe njani ngebhanki yakho, umniki-imeyile, njl. Ufuna ukuqinisekisa ukuba ayisebenzisi izinto ezingapheliyo abayeki qhekeka.
Ukubhaliweyo kusetyenziswa phantse yonke indawo kuzo zonke iintlobo zezicelo. Injongo ephambili yokusetyenziswa kwe-encryption kukukhusela ukugcinwa kwedatha, okanye ukukunceda ekukhuselweni kobugqwetha bomyalezo okanye ifayile. Ukubhaliweyo kungasetyenziselwa zombini idatha 'ngokuhamba', njengokuba ishukunyiswa ukusuka kwinkqubo enye ukuya kwelinye, okanye kwedatha 'ekuphumleni' kwiDVD, i-USB thumb drive, okanye enye indawo yokugcina.
Ndakuzalela ngembali ye-cryptography kwaye ndikuxelele indlela uJulius Caesar wasebenzisa ngayo izixhobo zokugcina imilayezo yempi kunye nayo yonke loo nto yezinto, kodwa ndiqinisekile ukuba kukho izigidi ezinye iimboniselo kumnatha onokunika ingqiqo ngakumbi kunokuba onokukunika, ngoko siya kudlula yonke loo nto.
Ukuba unjengam, ufuna ukuba izandla zakho zingcolile. Ndingumhlobo woluntu ofundayo. Xa ndiqalise ukufunda kwam encryption kunye ne-cryptography ngaphambi kokuthatha uvavanyo lwe-CISSP, ndazi ukuba ngaphandle kokuba ndikwazi "ukudlala" nge-encryption, ngoko andizange ndiyiqonde ngokwenene into eyenzeka emva kwezinto xa kukho into ebhaliweyo okanye ichithwe.
Andiyena matika, enyanisweni, ndiyingozi kakhulu kwimathematika. Andizange ndikhathalele ngokwenene ukwazi malunga nokulingana okubandakanyeka kwi-encryption algorithms kunye nenot, ndandifuna ukwazi oko kwenzekayo kwidatha xa ibhalwe ngefayile. Ndandifuna ukuqonda umlingo emva kwayo yonke into.
Ngoko, yintoni enye indlela engcono kakhulu yokufunda ngokubethela kunye ne-cryptography?
Ngethuba ndandifundela uviwo, ndenze uphando kwaye ndafumanisa ukuba esinye sezixhobo ezifanelekileyo ukuzisebenzisa ukuze ndifumane amava nge-encryption kwakuyi-application ebizwa ngokuba yi-CrypTool. I-CrypTool yayisungulwa ngokutsha yiDeutsche Bank emva ko-1998 kumzamo wokuphucula abasebenzi bayo ukuqonda ukuchaneka. Ukususela ngoko, i-CrypTool iye yavela kwiziko lezixhobo zemfundo kwaye isetyenziswe ezinye iinkampani, kunye neeyunivesithi, kunye nabani na ofuna ukufunda nge-encryption, cryptography, kunye ne-cryptanalysis.
I-Cryptool yasekuqaleni, eyaziwa ngokuba yi-Cryptool 1 (CT1), yayisisicelo esisekelwe kwi-Microsoft Windows. Ukususela ngelo xesha, kukho ezinye iinguqulelo ezikhutshwe njenge-Cryptool 2 (inguqulelo yesimanje ye-CrypTool, i-JCrypTool (ye-Mac, Win kunye ne-Linux), kunye neenguqu ezisekelwe kwi-browser-based ebizwa ngokuba yi-CrypTool-Online.
Zonke ezi zixhobo zineenjongo enye engqondweni: yenza i-cryptography into engabonakaliyo njengabantu abangafani ne-mathematian like me.
Ukuba ukufunda i-encryption kunye ne-cryptography kusenomncinci kwinqanaba elithandekayo, ungesabi, inxalenye engcono yantoni na ehlobene ne-crypto yinxalenye apho ufumana khona ikhowudi. I-Cryptanalysis yigama eliqhoshayo lokuphulwa kwekhowudi, okanye ukuzama ukufumanisa oko umyalezo ochitshiweyo, ngaphandle kokuba ukhiye. Le nto inomdla wokufunda zonke ezi zinto ngoba wonke umntu uthanda iphazili kwaye ufuna ukuba yintsikelelo yeentlobo.
Abantu be-CrypTool bafumana isayithi lokukhuphisana nabo bebeza kuba yi-code-breakers ebizwa ngokuba yi-MysteryTwister. Isayithi ikuvumela ukuba uzame inhlanhla yakho malunga nezixhobo ezifuna ipeni kunye nephepha kuphela, okanye unokunyuka ukuya kwimingeni enzima eyinkqubo efuna ezinye izakhono zohlelo kunye ne-computer enamandla.
Ukuba ucinga ukuba unayo oko kuthatha, unokuvavanya izakhono zakho ngokubhekiselele kwi "Cipras Unolved". Ezi zixhobo zihlalutyiweyo kwaye ziphandwa yiyona nto ibhetele kakhulu kwiminyaka kwaye ayengakabikho. Ukuba udibanisa enye yale nto ke unokuzifumana indawo kwindawo yomlando njengokuba umfana okanye umgca oqhekezayo ongenakucaciswa. Ngubani owaziyo, usenokuzihlawula umsebenzi kunye ne-NSA.
Ingongoma, ukubethela akufuneki kube yinto enkulu eyoyikisayo. Kungenxa yokuba umntu unobungozi kwimathematika (njengam) akuthethi ukuba abanakuqonda ukubethela kunye nokufunda ngokuzonwabisa malunga nalo. Nika i-CrypTool uzame, unokuba yilapho ehamba phambili ikhowudi-mphumela ngaphandle kwaye ungayazi.
I-CrypTool ikhululekile kwaye iyatholakala kwi-CrypTool Portal
