Question

11. (1 point) Suppose the followings are the RSA parameters: $p = 3$, $q = 11$, $e = 3$. Suppose Bob is sending the message ($m = 4$, signature = 14) to Alice but Eavesdropper intercepts the message and replaces it with ($m = 7^3 \mod 33$, signature = 7). What can Alice say about the authenticity and integrity of the message that she receives.

Step 1

We can find d by trying values: $3 \times 1 \equiv 3 \mod 20$ $3 \times 2 \equiv 6 \mod 20$ $3 \times 3 \equiv 9 \mod 20$ ... $3 \times 7 \equiv 21 \equiv 1 \mod 20$ So $d = 7$ Show more…
