Sobre IBD

Przesyłanie informacji cyfrowych wymaga zachowania ścisłej tajemnicy, zwłaszcza w przypadku obrazów cyfrowych. Zastosowanie konwencjonalnych algorytmów szyfrowania, takich jak Rivest-Shamir-Adleman, zaawansowany standard szyfrowania i standard szyfrowania danych, nie okazało się wystarczająco skuteczne, aby chronić wszystkie rodzaje obrazów cyfrowych. Z tego powodu szyfrowanie obrazów stało się pilnym wyzwaniem i przedmiotem zainteresowania wielu badaczy w ostatnich latach. Opracowano kilka schematów szyfrowania obrazów przy użyciu różnych technik, takich jak teoria kwantowa, kodowanie DNA, teoria chaosu. Jednak większość proponowanych schematów ma kilka wad pod względem bezpieczeństwa. W szyfrowaniu obrazów opartym na mapach chaotycznych bezpieczeństwo algorytmu szyfrowania zależy od charakterystyki map chaotycznych i struktury algorytmu, dlatego konieczne jest lepsze rozłożenie map chaotycznych. Jednak klasyczne systemy chaotyczne, takie jak mapy logistyczne i kwadratowe, mają wiele słabych punktów.
