Abstract
Description
In order to study the impact of the proposed NSA(New stream algorithm) algorithm reflections on the selection of security parameters, research was carried out, in which analysis methods and data presented in the literature were used. The output function of the NSA algorithm provides the 64-bit as the output value after the t-round. This requires investigating how small changes in input affect the NSA output function. Choosing any other array as the output array is easy to crack.
Mazkur maqolada taklif etilgan NSA(New stream algoritm) algoritmi akslantirishlarining tanlanishida xavfsizlik parametrlariga ta’sirini o‘rganish maqsadida tadqiqotlar o‘tkazildi, bunda adabiyotlarda keltirilgan tahlil usullari va ma’lumotlardan foydalanildi. NSA agoritmining chiqish funktsiyasi 64 bitli a2(t) ni t - raunddan so‘ng chiqish qiymati sifatida taqdim qiladi. Bunda NSA chiqish funksiyasiga kirishdagi kichik o‘zgarishlar qanday ta’sir etishini tekshirish talab etiladi. Chiqish massivi sifatida boshqa har qanday massiv tanlanganda shifrni osongina buzish mumkin bo‘ladi.
