Q6(1.5 point). Using the same notations as in the lecture, e.g., p and q are the two primes and e and d are the public key and the private key, respectively, p = 5, q11, e7. What is the value of phi(n) where phi(n) is the Euler Totient function of n and n is the modulus of RSA cipher?
Using the phi(n) that you found and the Extended Euclidean algorithm yields d = 23. What is the ciphertext C when encrypting M = 17?
Q7(0.5 point). Calculate the shared secret key using the Diffie-Hellman key exchange protocol with specific data. Given the following parameters:
Prime number p: 79
Primitive root g: 5
Alice's secret value (a): 11
Bob's secret value (b): 7
Q8(0.5 point) Using initial setups and Diffie-Hellman parameters as:
Prime number p: 79
Primitive root g: 5
Alice's secret value (a): 11
Bob's secret value (b): 7
