Kryptografowie muszą zapewnić światu nowy standard szyfrowania. DES, główny algorytm szyfrujący przez ostatnie piętnaście lat, zbliża się do końca swojego okresu użyteczności. Nowszy atak, nazwany XSL, proponuje nowy atak na AES i Serpent. Szczególnie podatne na atak są szyfry o małych S-boxach i prostych strukturach. Serpent ma małe S-boxy i prostą strukturę. AES ma większe S-boxy, ale bardzo prosty opis algebraiczny. Wiele z innych niezłamanych algorytmów - Khufu, REDOC II, i IDEA - jest chronionych patentami. RC2 jest złamany. Rząd Stanów Zjednoczonych odtajnił algorytm Skipjack w układach Clipper i Capstone. Jeśli świat ma mieć bezpieczny i ogólnodostępny algorytm szyfrowania, musimy teraz opracować kilka kandydujących algorytmów szyfrowania. Algorytmy te mogą być następnie poddane latami publicznej kontroli i kryptoanalizie. W książce zaproponowano algorytm szyfru blokowego z kluczem prywatnym. Rozmiar bloku jest definiowany przez użytkownika, a klucz może mieć nieskończoną długość. Algorytm ten jest pierwszym w swoim rodzaju algorytmem dynamicznym, w którym prawie wszystkie elementy zmieniają się w zależności od samego hasła użytego do wygenerowania klucza lub zaszyfrowania pliku.
