Abstract
Annotatsiya: Ushbu ishda massiv elementlarini uzluksiz almashtirishga asoslangan uzluksiz shifrlash algoritmlarining qurilishi va ularning xavfsizligini ta'minlashda psevdotasodifiy sonlar generatoridan foydalanishning ahamiyati ko‘rib chiqilgan. Ishlab chiqilgan algoritm, bir o‘lchovli P-massiv va ikki o‘lchovli S-massivdan iborat bo‘lib, kirish parametrlari sifatida kalit massivi, siqish jadvali va bir baytli psevdotasodifiy hosil qilingan bayt qabul qiladi. Algoritmning asosiy bosqichlari, jumladan boshlang‘ich holatdan P-massivni aralashtirish, kalit massiv yordamida P-massivni qayta ishlash va tasodifiy bloklar generatsiyasi ko‘rsatib o‘tilgan. Taklif etilgan usulning samaradorligi va xavfsizligi, AES standartida foydalanilgan S-jadval sifatidagi ixtiyoriy bardoshli jadvalga asoslanadi. Shuningdek, HMAC algoritmini sanoq rejimida foydalanishga asoslangan psevdotasodifiy sonlar generatorining amalga oshirilishi tavsiflanadi.
