Kiedy dyskutujemy o bezpieczeństwie i sieciach, nigdy nie pamiętamy o wkladzie metod i technik szyfrowania i deszyfrowania. W ciągu ostatnich kilku lat technologia obliczeń DNA szybko się rozwija i może miec swój wklad w różne metodologie obliczeń miękkich i algorytmy bezpieczeństwa.Podczas poszukiwań skutecznego, wydajnego i niezawodnego algorytmu szyfrowania obrazów znaleziono wiele wysilków i propozycji. W tym projekcie pracujemy nad techniką szyfrowania obrazu przy użyciu techniki dodawania sekwencji DNA. Proponowana technika Po pierwsze, obraz jest konwertowany na macierz binarną po podzieleniu macierzy na kilka równych bloków. Po drugie, każdy blok jest kodowany w sekwencjach DNA i wykorzystywana jest operacja dodawania sekwencji DNA w celu dodania tych bloków. Po trzecie, przeprowadzana jest operacja uzupelniania sekwencji DNA dla wyniku dodanej macierzy przy użyciu dwóch map logistycznych. Wreszcie, dekodując macierz sekwencji DNA z trzeciego kroku, otrzymamy zaszyfrowany obraz. Wyniki eksperymentów symulacyjnych i analiza bezpieczeństwa pokazują, że nasz algorytm nie tylko może uzyskac lepszy efekt szyfrowania, ale także może oprzec się atakowi wyczerpującemu, atakowi statystycznemu i atakowi różnicowemu.
