Using the basic Diffie-Hellman scheme with p = 257 and α = 7, let Alice select x = 4, and let Bob choose y equal to the ASCII value of the first letter of your last name (65 ≥ y ≤ 90). What is the first letter of your last name and its ASCII value? What is the value of αx and αy? Finally what is the key K that Alice and Bob decide upon?

Can you help me with the code in MATLAB?

You know that the truth value of the statement (p q) → r is Truth. What can you say about the truth value of the following statement: ~r→ (~ pV ~ q) OTHER False cannot be decided Truth

Suppose you and your friend would like to use Diffie-Hellman key exchange system to exchange a keyword. Both of you have decided to use the following p = 4138327577, q = 3742197127.If you decide b = 1767005, and your friend has picked a number a that you don’t know. But you havereceived q a mod p from your friend, and the number is 980246808. Find out the common shared key.

For the following NFA M. 1 start 90 qi q2 From the list below, select all computations of M on the string 100. O go → go q1 → 92 92 qo → qo → q1 → q1 q0 → q0 → qi → q1 → q2
