Kuyankhulana kwa ife omwe sitiri masabata
WPA2 , WEP , 3DES, AES, Symmetric, Asymmetric, zonsezi zikutanthauzanji, ndipo n'chifukwa chiyani muyenera kusamala?
Mawu onsewa akugwirizana ndi matekinoloje okhotakhota omwe amagwiritsidwa ntchito poteteza deta yanu. Kulemba ndi kujambula kwapadera, kungakhale kovuta mitu kuti mukulunge mutu wanu kuzungulira. Nthawi zonse ndikamva mawu a cryptographic algorithm, ndikuwona pulofesa wina yemwe akulemba zofanana pa bolodi, akudzidandaulira yekha za Medulla Oblongata momwe maso anga akuyang'anitsitsa chifukwa cha kudzimva.
N'chifukwa chiyani muyenera kusamala za encryption?
Chifukwa chachikulu chimene mukufunikira kusamalira za kutsekedwa ndi chifukwa chakuti nthawi zina ndi chinthu chokha pakati pa deta yanu ndi anthu oipa. Muyenera kudziwa zofunikira kuti mutha kudziwa momwe deta yanu imatetezedwera ndi banki, makalata olemba makalata, ndi zina zotero. Mukufuna kuonetsetsa kuti sakugwiritsa ntchito zinthu zomwe zasokonezedwa kale. atasweka.
Kulemba kwachinsinsi kumagwiritsidwa ntchito pafupi kulikonse mu mitundu yonse ya mapulogalamu. Cholinga chachikulu cha kugwiritsa ntchito encryption ndiko kuteteza chinsinsi cha deta, kapena kuthandiza kuteteza umphumphu wa uthenga kapena fayilo. Kulemba kwachinsinsi kungagwiritsidwe ntchito ponseponse deta 'poyenda', monga pamene akusunthira kuchoka ku njira imodzi kupita ku ina, kapena kuti deta 'ipumule' pa DVD, USB thumb, kapena yosungirako zina.
Ndikutha kukubwerani ndi mbiri ya kujambula ndikukuuzani momwe Julius Caesar anagwiritsira ntchito mauthenga amtundu wankhondo kuti athandize mauthenga a usilikali ndi zinthu zonsezi, koma ndikukhulupirira kuti pali zowonjezera zowonjezera zowonjezera zowonjezera kuposa ine angapereke, kotero ife tidzasambira zonsezo.
Ngati muli ngati ine, mukufuna kuti manja anu azikhala odetsedwa. Ndine mtundu wa munthu wophunzira. Pamene ndinayambitsa kuphunzira kwanga ndikuyimitsa chinsinsi ndisanayambe kufufuza kwa CISSP, ndinadziwa kuti ngati sinditha "kusewera" ndi kufotokozera, ndiye kuti sindingathe kumvetsetsa zomwe zikuchitika pamasewera pamene chinachake chikuphatikizidwa kapena chitayidwa.
Sindiri katswiri wa masamu, makamaka, ndikuwopsya masamu. Sindinkafuna kudziŵa za equation zomwe zimagwiritsidwa ntchito muzitsulo zogwiritsira ntchito ndi zomwe sizinachitike, ndimangofuna kudziwa zomwe zikuchitika pa deta pamene itsekedwa. Ndinkafuna kumvetsa zamatsenga pambuyo pake.
Kotero, ndi njira yanji yabwino yophunzirira za kulembedwa ndi kujambula?
Pamene ndikuphunzira kuti ndiyambe kufufuza, ndinapanga kafukufuku ndikupeza kuti imodzi mwa zipangizo zabwino kwambiri zomwe mungagwiritse ntchito kuti mukhale ndi chidziwitso ndikutumizira CrypTool. CrypTool poyamba inakhazikitsidwa ndi Deutsche Bank mmbuyo mu 1998 pofuna kuyesetsa kukonza antchito ake kumvetsetsa zojambulajambula. Kuchokera nthawi imeneyo, CrypTool yasintha n'kukhala m'gulu la zipangizo zamaphunziro ndipo amagwiritsidwa ntchito ndi makampani ena, komanso maunivesites, ndi wina aliyense amene akufuna kuphunzira za kubisala, cryptography, ndi cryptanalysis.
Cryptool yoyamba, yomwe tsopano imatchedwa Cryptool 1 (CT1), inali ntchito ya Microsoft Windows. Kuyambira nthawi imeneyo, pakhala pali mabaibulo angapo omwe amamasulidwa monga Cryptool 2 (a modernized version of CrypTool, JCrypTool (Mac, Win ndi Linux), komanso ndiwongolerani makawuni wotchedwa CrypTool-Online.
Mapulogalamu onsewa ali ndi cholinga chimodzi m'malingaliro: kupanga zojambulajambula zomwe anthu osakhala a masamu monga ine amatha kumvetsa.
Ngati kuphunzira kuwerenga ndi kufotokozera mawu kumapitirizabe kumveka pang'onopang'ono, osawopa, gawo labwino kwambiri la zokhudzana ndi crypto ndilo gawo limene mumapeza. Cryptanalysis ndi mawu okongoletsa kulemba-kachidindo, kapena kuyesa kupeza zomwe uthenga wosokonezeka uli, popanda kukhala ndi fungulo. Ichi ndi gawo losangalatsa la kuphunzira zinthu zonsezi chifukwa aliyense amakonda puzzles ndipo amafuna kukhala wowononga.
Anthu a CrypTool ngakhale ali ndi malo otetezera omwe angakhale odula malamulo omwe amatchedwa MysteryTwister. Webusaitiyi imakulolani kuyesa mwayi wanu wolemba pepala ndi pepala, kapena mukhoza kuthana ndi zovuta zambiri zomwe zimafuna luso la pulogalamu pamodzi ndi mphamvu yaikulu ya pakompyuta.
Ngati mukuganiza kuti muli ndi zomwe zimatengera, mukhoza kuyesa luso lanu polimbana ndi "Ciphers chosasinthidwa". Zosintha izi zafufuzidwa ndi kufufuzidwa ndi zabwino koposa kwa zaka ndipo sizinasokonezeke. Ngati mutasokoneza imodzi mwa izi ndiye kuti mumangodzipezerapo malo m'mbiri monga mnyamata kapena gal yemwe anaphwanya zosokoneza. Ndani amadziwa, mwina mungadzipangire nokha ntchito ndi NSA.
Mfundo ndiyakuti, kulembera sikumayenera kukhala nyamayi yowopsya. Chifukwa chakuti wina ndi wovuta pa masamu (monga ine) sizikutanthauza kuti sangathe kumvetsetsa ndi kusangalala nazo. Perekani CrypTool kuyesa, iwe ukhoza kukhala wotsatira wotsutsa kwambiri kunja uko ndipo osadziwa nkomwe izo.
CrypTool ili mfulu ndipo imapezeka pa CrypTool Portal
