Pytania
Co można powiedzieć po porównaniu tych skrótów?
Po porównaniu skrótów wiadomości przed i po modyfikacji można zauważyć, że nawet drobna zmiana (np. usunięcie pojedynczego znaku) prowadzi do całkowicie innego wyniku funkcji skrótu. Jest to cecha charakterystyczna funkcji skrótu zwana efektem lawiny, która zapewnia, że zmiana choćby jednego bitu danych wejściowych znacznie zmienia wartość skrótu.
Jakiej długości (wyrażonej w bitach) są poszczególne skróty?
- MD5: 128 bitów (16 bajtów)
- SHA1: 160 bitów (20 bajtów)
- SHA-256: 256 bitów (32 bajty)
Każda funkcja skrótu zawsze generuje wynik o ustalonej długości niezależnie od długości danych wejściowych.
Zadanie 2
Treść Zadania:
W tym zadaniu wykorzystywany jest przykładowy algorytm skrótu zaimplementowany w języku C (program iha1.c) Algorytm nazywa się IHA1 (Insecure Hash Agorithm) i działa na zasadzie funkcji XOR wykonywanej bitowo, a wynikiem jest liczba reprezentowana na 4 bitach (jedna cyfra w zapisie hexadecymalnym).
Krok 1: Dokonaj kompilacji pliku iha1.c poprzez wydanie polecenia:
gcc iha1.c -o iha1
Krok 2: Przygotuj plik z tekstem jawnym np. „This is a test message”.
Krok 3: Użyj funkcji iha1 do obliczenia skrótu wiadomości zapisanej w w/w pliku.
Składnia wywołania jest następująca:
iha1 nazwa_pliku
Przykładowy wynik działania programu iha1:
root@kali:~/lab11/support> ./iha1 message iha1(message) = A
Krok 4: Spróbuj znaleźć kolizję (stwórz inną wiadomość jawną która będzie miała taki sam skrót co wiadomość stworzona w tym zadaniu). W tym celu wykonaj 160 prób, w każdej próbie podając na wejście funkcji skrótu inną wartość.

Pytania
Ile średnio potrzebnych jest operacji, żeby znaleźć kolizję dla wyżej opisanego przypadku? Odpowiedź uzasadnij.
Algorytm IHA1 zwraca wynik skrótu reprezentowany jako jedna cyfra szesnastkowa, co oznacza że wynik może przyjąć jedną z 16 wartości (od 0 do F, czyli $2^4 = 16$ możliwych wyników).
Zgodnie z teorią prawdopodobieństwa oraz tzw. paradoksem urodzin, średnia liczba operacji potrzebna do znalezienia kolizji dla funkcji skrótu o $n$ możliwych wartościach wynosi około: $$\sqrt{\frac{\pi n}{2}} \approx 1.253 \cdot \sqrt{n}$$ Dla $n = 16$: $$\sqrt{\frac{\pi \cdot 16}{2}} \approx \sqrt{8\pi} \approx 5.01$$
Zatem średnio potrzeba około 5 różnych wiadomości (czyli 4–5 prób), aby z dużym prawdopodobieństwem znaleźć kolizję dla funkcji skrótu zwracającej 4-bitowy wynik. W najgorszym przypadku może to być do 16 prób, jednak statystycznie znacznie szybciej znajdziemy kolizję.

Pytania
Co musi wiedzieć użytkownik maszyny B jeżeli chce zweryfikować prawdziwość skrótu HMAC z kluczem? Odpowiedź uzasadnij.
Użytkownik maszyny B musi znać dokładnie ten sam klucz symetryczny, który został użyty przez maszynę A do obliczenia funkcji HMAC. Jest to niezbędne, ponieważ funkcja HMAC wykorzystuje klucz nie tylko do skrócenia wiadomości, ale do generowania unikalnego podpisu kryptograficznego. Bez znajomości tego klucza niemożliwe jest odtworzenie tego samego HMAC i tym samym jego weryfikacja.
Jakie operacje musi wykonać użytkownik maszyny B jeżeli chce zweryfikować prawdziwość wiadomości i skrótu otrzymanych od użytkownika maszyny A? Odpowiedź uzasadnij.
Aby zweryfikować prawdziwość wiadomości i skrótu HMAC, użytkownik maszyny B musi:
- Otrzymać wiadomość i oryginalny HMAC od użytkownika maszyny A.
- Upewnić się, że posiada ten sam klucz, który został użyty do wygenerowania HMAC.
- Obliczyć lokalnie nowy HMAC z otrzymanej wiadomości, używając tego samego algorytmu (MD5) i klucza.
- Porównać wynik z otrzymanym HMAC.
Jeśli oba skróty są identyczne, oznacza to, że wiadomość nie została zmodyfikowana oraz że HMAC został wygenerowany z właściwego klucza. W przeciwnym razie wiadomość mogła zostać zmieniona lub klucz jest niepoprawny.
Zadanie 4
Treść Zadania: Dokonaj oceny wydajności algorytmów obliczających skrót wiadomości. Wypełnij Tabelę 1 wpisując wartość średnią czasu obliczania funkcji skrótu obliczoną z 12 pomiarów. Stwórz pliki o rozmiarach: 100kB, 1MB, 10MB, 100MB. Do tego celu można użyć poniższej komendy:
openssl rand -out nazwa_pliku.txt rozmiar_pliku_w_bajtach
Do sprawdzenia czasu wykonywania operacji obliczania skrótu można wykorzystać komendę ’time’:
time polecenie_obliczające_skrót
Przykładowy wynik polecenia: time
real 0m5.126s user 0m0.004s sys 0m0.012s
Wpisz przedziały ufności obliczone dla poziomu ufności równego 95%. Wyniki przedstaw również w postaci wykresu. W sprawozdaniu umieść analizę wyników wydajności obliczania funkcji skrótu (sprawdź wyniki – uzyskane czasy dla różnych rozmiarów wiadomości wejściowych oraz dla różnych rozmiarów funkcji skrótu).

Analiza wydajności dla każdego algorytmu
Poniżej zestawiono średnie czasy „real” (w sekundach) i 95% przedziały ufności dla 12 pomiarów każdego algorytmu i rozmiaru pliku. Wspólny współczynnik t-Studenta dla 11 stopni swobody: $t_{0.975,11}\approx2.201$.
Wzory obliczeniowe
Średnia arytmetyczna
$$\bar{x} \;=\;\frac{1}{n}\sum_{i=1}^{n}x_i$$
- $x_i$ wartość $i$-tego pomiaru czasu,
- $n$ liczba pomiarów (w naszym przypadku $n=12$),
- $\bar{x}$ średnia arytmetyczna zestawu pomiarów.
Odchylenie standardowe próbki
$$s \;=\;\sqrt{\frac{1}{n-1}\sum_{i=1}^{n}(x_i - \bar{x})^2}$$
- $x_i$ wartość $i$-tego pomiaru,
- $\bar{x}$ średnia arytmetyczna pomiarów,
- $n$ liczba pomiarów,
- $s$ odchylenie standardowe obliczone dla próby.
Przedział ufności 95%
$$\bar{x} \;\pm\; t_{\alpha/2,\;n-1}\,\frac{s}{\sqrt{n}}$$
- $\bar{x}$ średnia arytmetyczna pomiarów,
- $s$ odchylenie standardowe próby,
- $n$ liczba pomiarów,
- $\alpha$ poziom istotności (tutaj $\alpha=0{,}05$ dla 95% ufności),
- $t_{\alpha/2,\;n-1}$ wartość statystyki t-Studenta dla rozkładu o $n-1$ stopniach swobody (tutaj $t_{0{,}975,11}\approx2{,}201$),
- $\displaystyle\frac{s}{\sqrt{n}}$ błąd standardowy średniej.
