“…Even if several works have been published on this notion (e.g., [5,11,18,22]), we exhibited several inconsistencies in the definition as well as in the interpretation of the definition that went unnoticed for a long time. We have then conducted an in-depth analysis of the notion which led us to output a revised definition which answers all the issues identified in the previous version.…”

“…[1]'de, bir S-kutusunun FGA dayanıklılıgı saydamlık derecesi (SD) kavramı ortaya konularak nicelleştirilmiş ve bu ölçütün geçerliligi SASEBO-GII kartı [2][3][4] ve ATmega163 akıllı kart [5,6] gibi kriptografik cihazlar üzerinde uygulanan birçok implementasyon ile dogrulanmıştır.…”

“…Yakın zamanda gerçekleştirilen bazı çalışmalarda [6,8,9], bir S-kutusunun FGA dayanıklılıgının dogrusal olmama, farksal birbiçimlilik ve cebirsel gibi kriptografik özel-likleri degişmeden afin dönüşümlerle iyileştirilebilecegi tespit edilmiştir. Bir S-kutusunun uzaklık profili FGA dayanıklılıgının göstergesi olarak tanımlandıgında, bütün (genişletilmiş) afin eşdeger S-kutuları arasında ikinci en düşük uzaklıga sahip (mutlak gösterge degeri 8 ve boyutu 4 olan) optimal S-kutularının [10], blokşifre PRINCE [11] için öngörülen 8 S-kutusu yerine kullanılmaları öner-ilmiştir [9].…”
