Video tabanl\u0131 kriptanaliz sald\u0131r\u0131s\u0131<\/h2>\n

Bu teknolojiyi kullanan ger\u00e7ek bir sald\u0131r\u0131 hayal edelim. B\u00f6yle bir sald\u0131r\u0131 a\u015fa\u011f\u0131daki \u015fekilde geli\u015febilir. Sald\u0131rganlar, bir \u015firket binas\u0131ndaki video g\u00f6zetim sistemine eri\u015fim sa\u011flar. Kameralardan biri gizli belgelerin tutuldu\u011fu y\u00fcksek g\u00fcvenlikli bir depo odas\u0131n\u0131n kap\u0131s\u0131na do\u011frultulmu\u015f olsun. Kap\u0131da da ak\u0131ll\u0131 kart okuyucu var. Bir \u015firket \u00e7al\u0131\u015fan\u0131 kap\u0131ya yakla\u015f\u0131yor ve kart\u0131n\u0131 okuyucuya sokuyor; b\u00f6ylece kilit a\u00e7\u0131l\u0131yor.<\/p>\n

Ak\u0131ll\u0131 kart, okuyucuyla etkile\u015fime giren bir mikro\u00e7ip i\u00e7erir. Ak\u0131ll\u0131 kartta kodlanan anahtar\u0131 okuyucudaki verilerle do\u011frulamak i\u00e7in okuyucu kriptografik bir algoritma, yani bir dizi hesaplama ger\u00e7ekle\u015ftirir. Normal bir durumda, orijinalini ele ge\u00e7irmeyi ba\u015farsan\u0131z bile b\u00f6yle bir anahtar\u0131n kopyas\u0131n\u0131 \u00e7\u0131karmak son derece zordur. Ancak bu senaryoda bir g\u00fcvenlik a\u00e7\u0131\u011f\u0131 var: okuyucunun LED\u2019i. Bu durum, cihaz\u0131n \u00e7al\u0131\u015ft\u0131\u011f\u0131 anlam\u0131na gelir. Yani, bir ziyaret\u00e7iye izin verildi\u011finde ve kap\u0131n\u0131n a\u00e7\u0131labilece\u011fi durumlarda, LED\u2019in rengi k\u0131rm\u0131z\u0131dan ye\u015file d\u00f6necektir.<\/p>\n

G\u00f6stergenin parlakl\u0131\u011f\u0131, okuyucu sistemlerindeki y\u00fcke ba\u011fl\u0131 olarak kriptografik i\u015flem s\u0131ras\u0131nda de\u011fi\u015fir. \u00d6rne\u011fin, okuyucunun i\u015flemcisi hesaplamalarla me\u015fgul oldu\u011funda LED parlakl\u0131\u011f\u0131 biraz d\u00fc\u015fer. Bu k\u00fc\u00e7\u00fck de\u011fi\u015fimleri analiz ederek, \u00f6zel anahtar\u0131 yeniden olu\u015fturmak ve b\u00f6ylece gizli odan\u0131n kap\u0131s\u0131n\u0131 a\u00e7an bir ak\u0131ll\u0131 kart yaratmak m\u00fcmk\u00fcnd\u00fcr. Potansiyel sald\u0131rganlar\u0131n binadaki bir video kameraya eri\u015fimi varsa ve okuyucu LED\u2019inin video g\u00f6r\u00fcnt\u00fclerini alabilirlerse, teorik olarak binan\u0131n g\u00fcvenlik sistemine girebilirler.<\/p>\n

Pratikteki zorluklar<\/h2>\n

Bu gibi makalelerdeki teoriyi prati\u011fe d\u00f6kmek hi\u00e7bir zaman kolay de\u011fildir. Yukar\u0131daki senaryonun yak\u0131n zamanda pratikte uygulanmas\u0131 olas\u0131 de\u011fildir. Donan\u0131m g\u00fcvenli\u011fi uzmanlar\u0131 a\u00e7\u0131s\u0131ndan bakt\u0131\u011f\u0131m\u0131zda ise bu g\u00fcvenlik a\u00e7\u0131\u011f\u0131 yeni bir \u015fey de\u011fil. Bu, klasik bir yan kanal sald\u0131r\u0131s\u0131 durumudur. Ba\u015fka bir deyi\u015fle, bir cihaz\u0131n i\u015fleyi\u015finde \u00f6n planda olmay\u0131p g\u00f6r\u00fcnmeyen baz\u0131 i\u015flemleri kullanarak veri s\u0131zd\u0131rmak. Veri \u015fifreleme algoritmalar\u0131 kullanan ak\u0131ll\u0131 kartlara ve di\u011fer cihazlara sald\u0131r\u0131rken kullan\u0131lan geleneksel y\u00f6ntem, cihazdaki voltaj\u0131 \u00f6l\u00e7mektir. Hesaplamalar s\u0131ras\u0131nda bu voltaj biraz de\u011fi\u015fir. Bir sald\u0131rgan, bu k\u00fc\u00e7\u00fck de\u011fi\u015fiklikleri g\u00f6zlemleyerek algoritmay\u0131 tersine \u00e7evirebilir: \u00f6rne\u011fin, bir voltaj d\u00fc\u015f\u00fc\u015f\u00fcn\u00fc i\u015flenmekte olan belirli bir de\u011ferle ili\u015fkilendirebilir.<\/p>\n

Bu t\u00fcr yan kanal sald\u0131r\u0131lar\u0131n\u0131n bir \u00f6zelli\u011fi de hesaplamalar\u0131n \u00e7ok h\u0131zl\u0131 olmas\u0131d\u0131r. \u015eifreleme anahtar\u0131n\u0131 yeniden yap\u0131land\u0131rmak i\u00e7in voltaj\u0131 saniyede y\u00fczlerce hatta binlerce kez \u00f6l\u00e7mek gerekir. Ancak LED, cihaz\u0131n genel g\u00fc\u00e7 kayna\u011f\u0131 devresinin bir par\u00e7as\u0131d\u0131r, bu da LED parlakl\u0131\u011f\u0131n\u0131n voltaja g\u00f6re de\u011fi\u015fti\u011fi anlam\u0131na gelir. Bu alandaki ilerlemeleri g\u00f6z ard\u0131 etmeyin; \u00e7\u00fcnk\u00fc LED odakl\u0131 sald\u0131r\u0131lar art\u0131k karma\u015f\u0131k ve pahal\u0131 ekipman gerektirmiyor. Art\u0131k cihaz\u0131 par\u00e7alara ay\u0131rmaya ve kablolar\u0131 devre kart\u0131na lehimlemeye gerek yok. Sadece video kameray\u0131 LED\u2019e do\u011frultman\u0131z, kay\u0131t alman\u0131z ve kayd\u0131 analiz etmeniz istedi\u011finiz sonucu alman\u0131z i\u00e7in yeterli.<\/p>\n

Makalenin yazarlar\u0131, video g\u00f6r\u00fcnt\u00fclerini pratikte analiz ederken \u00e7ok say\u0131da zorlukla kar\u015f\u0131la\u015ft\u0131. Normal bir kamera saniyede 60 kare h\u0131z\u0131nda video \u00e7ekerken, geli\u015fmi\u015f bir kamera ise en fazla 120 kare h\u0131z\u0131nda video kaydedebilir. \u015eifreleme algoritmas\u0131n\u0131 hedefleyen bir sald\u0131r\u0131 i\u00e7in bu olduk\u00e7a d\u00fc\u015f\u00fck bir de\u011ferdir.

Bu da yan kanal sald\u0131r\u0131lar\u0131 hakk\u0131nda bildiklerimize \u00f6nemli bir katk\u0131 sa\u011fl\u0131yor.

Sonu\u00e7ta, inceledi\u011fimiz makalenin de hakl\u0131 olarak i\u015faret etti\u011fi gibi, gizli bilgileri if\u015fa etmeyen bir LED yapmak olduk\u00e7a basittir. \u00d6rne\u011fin, g\u00fc\u00e7 kayna\u011f\u0131 devresine \u00e7ok ucuz bir kapasit\u00f6r eklemek bu sorunu \u00e7\u00f6zer.
