I-Bug ye-Copy-Cola Eyophule i-PSpice AES-256 Encryption

I-Copy-Cola Bug Eyophule i-PSpice AES-256 Encryption

Ehlabathini lophuhliso lwesoftware, obona buthathaka bubaluleke kakhulu kaninzi abuveli kwiintsilelo ezintsonkothileyo ze-algorithmic, kodwa ukusuka kulawulo olulula, lwabantu. Isikhumbuzo esicacileyo sale nyaniso savela ngenxa yesiphene esibalulekileyo esifunyenwe kwi-PSpice, isoftware yokulinganisa isekethe esemgangathweni evela kwiCadence. I-bug, eyayihlala ekuphunyezweni kwe-AES-256 encryption algorithm, yayinemvelaphi engathandekiyo: impazamo yokukopisha-uncamathisele. Esi siganeko sigxininisa umngeni wendalo yonke kubunjineli besoftware kwaye sigxininisa ukuba kutheni iimodyuli, amaqonga anokuphicothwa afana neMewayz esiba yimfuneko ekwakhiweni kweenkqubo zoshishino ezinokomelela. Ibali lale ntsholongwane sisilumkiso malunga neendleko ezifihlakeleyo zokuphindaphinda ikhowudi kunye nobuthathaka boyilo lwesoftware ye-monolithic.

I-Anatomy ye-Cryptographic Catastrophe

Igciwane lifunyenwe `cryptlib` ilayibrari yoguqulelo oluntsonkothileyo olusetyenziswa yiPSpice ngeempawu zayo zoguqulelo oluntsonkothileyo. Kwisiseko sayo, i-Advanced Encryption Standard (AES) isebenza kwimijikelezo emininzi yokucubungula. Kwi-AES-256, kukho imijikelo eyi-14 enjalo. Umjikelo ngamnye ufuna "isitshixo esijikelezayo," esiphuma kwiqhosha lokuqala lofihlo ngokusebenzisa inkqubo ebizwa ngokuba kukwandiswa kwesitshixo. Umsebenzi womphuhlisi yayikukubhala i-loop ukusebenzisa le mijikelo ili-14. Nangona kunjalo, endaweni yokucoceka, i-loop ephindaphindayo, ikhowudi yacwangciswa ngeebhloko ezimbini eziphantse zifane: enye kwimijikelo elithoba yokuqala kunye neyokugqibela emihlanu. Ngethuba lomsebenzi wokukopisha kunye nokunamathisela, umgca obalulekileyo wekhowudi owenza inyathelo lokutshintsha ushiywe ngengozi kwibhloko yesibini. Oku kuthetha ukuba kwimijikelo emihlanu yokugqibela yoguqulelo oluntsonkothileyo, inxalenye ebalulekileyo ye-algorithm ye-AES yatsitywa nje, yenze buthathaka ngokuyintlekele uguqulelo.

Kutheni i-Monolithic Codebites ivelisa i-Bugs

Le mpazamo iqhubekile ingaqatshelwanga iminyaka kuba ibingcwatywe ngaphakathi kwesiseko sekhowudi ye-monolithic. Kwiimeko-bume ezinjalo, imodyuli enye efana ne `cryptlib` ilokwe ngokuqinileyo kwilaphu lesicelo, yenze uvavanyo olulodwa kunye noqinisekiso lube nzima. Ingqiqo yemijikelo yoguqulelo oluntsonkothileyo yayingeyonto izimeleyo, iyunithi evavanywa ngokulula kodwa iqhekeza lephazili enkulu kakhulu. Oku kunqongophala kwemodyuli yeyona nto iphambili yomngcipheko kwisoftware yeshishini. Idala iindawo ezingaboniyo apho impazamo elula kumsebenzi omnye inokubeka esichengeni ukhuseleko lwenkqubo yonke, kufana necandelo elinye elineziphene linokumisa umgca wemveliso ontsonkothileyo. Yilapho ifilosofi emva kwei-OS yemodyuli yeshishini efana neMewayzibonisa enye indlela enyanzelisayo. Ngokuyila iinkqubo ezineemodyuli ezicacileyo, ezinokuthathelwa indawo, amashishini angakwazi ukwahlula ukusebenza, ukwenza amacandelo ahlukeneyo aphicothwe, avavanywe, kwaye ahlaziywe ngaphandle kokubeka umngcipheko wokuwohloka kwenkqubo.

Izifundo zoPhuhliso lweSoftwe yanamhlanje

I-PSpice bug ifundisa izifundo ezininzi ezibalulekileyo ezidlulela ngaphaya kwesoftware yokulinganisa isekethe:

• Ingozi yokuphindaphinda: Ikhowudi yokukopa ngumthombo owaziwayo weempazamo. Lonke uphinda-phindo yindawo enokubakho yeyantlukwano yexesha elizayo kunye nentshayelelo yempazamo.
• Uvavanyo lweYunithi aluxoxiswana: Uvavanyo lweyunithi olubanzi lomsebenzi woguqulelo oluntsonkothileyo lwe-AES, ukukhangela imveliso ngokuchasene neevektha ezaziwayo eziqinisekisiweyo, ngekubambe oku ngoko nangoko.
• Uphononongo lweKhowudi lugcina iiNkqubo: Isibini samehlo, ngakumbi kumacandelo abaluleke kakhulu kukhuseleko, yenye yezona ndlela zisebenzayo zokubamba ibug.
• Ulula ngaphezu koBuchule: I-loop elula, ecacileyo ye-14 imijikelo bekuya kuba nempazamo encinci kakhulu kunesakhiwo sebhloko ekwahlulahlulwe.

"Obu buthathaka bubonisa ukuba amandla e-cryptosystem angekho kuphela kwimathematika ye-algorithm kodwa ngokulinganayo ekuchanekeni kokuphunyezwa kwayo. I-slip enye kwikhowudi inokunciphisa i-AES-256 kwinqanaba lobuthathaka obuncinane ukuphuka." – Uhlalutyo loPhando loKhuseleko

Ukwakha kwiSiseko seModyuli yeMfezeko

Ukungaphumeleli kwesi siphene kufune ukuba iCadence ikhuphe isiqwenga esibalulekileyo, kunyanzele iifemu zobunjineli ezininzi ukuba zihlaziye ngokukhawuleza isoftware yazo ebaluleke kakhulu. Ukuphazamiseka kunye nomngcipheko wokhuseleko olunokwenzeka lwalubalulekile. Kumashishini namhlanje, ukuxhomekeka kwi-monolithic, isoftware yebhokisi emnyama ithwala umngcipheko wokusebenza. Iiqonga elifana neMewayzilungisa oku ngokuphatha imisebenzi engundoqo yeshishini-ukusuka ekuphatheni idatha kwiiprotocol zokhuseleko-njengeemodyuli ezizimeleyo ngaphakathi kwenkqubo yokusebenza ngokubambisana. Olu lwakhiwo luvumela ukuqinisekiswa okuqhubekayo, okuzimeleyo kwecandelo ngalinye. Ukuba ubuthathaka bufunyenwe kwimodyuli enye, bunokutshintshwa okanye butshintshwe ngaphandle kokuqhawula lonke uhambo lweshishini. Ngokwenyani, i-Mewayz ikhuthaza uhlobo loyilo lwesoftware ecocekileyo, elondolozekayo, kunye nokuphicothwayo ethintela "iimpazamo zekopi-uncamathisele" ekubeni zibe ziingxaki kwinqanaba leshishini, iqinisekisa ukuba imfezeko yengqiqo yeshishini lakho ayize ithotyelwe ngempazamo enye, elula.
