1. The following exercises are on prime numbers.Use the Miller-Rabin Primality Test to test whether n = 157 is a prime. Choose the random value a = 8.

Alice and Bob use the RSA cryptosystem with p = 11, q = 31, and e = 19. Compute Bob’s private key.

Explain how Alice encrypts the message x = 14 using the public key and compute the encrypted message y.

Alice and Bob want to set up a symmetric cryptographic channel using the Diffie-Hellman key exchange protocol. Alice chooses p = 457 and needs to find a generator of Zp. How would you test if g is a generator of Zp? How many exponents a ≥ 1 do you need to test at most to prove that a given g is a generator of Z∗457?Hint: The order ordG(g) of any element g ∈ G must divide the order of the finite group G.

An appliance repair shop has 5 electric fans, 12 washing machines, and 18 air conditioning units to be repaired. The store employs two part-time repairmen. Repairman A can repair 3 electric fans, 3 washing machines, and 4 airconditioning units in a week, while Repairman B can repair 1 electric fan, 3 washing machines, and 6 air conditioning units in a week. repairman A is paid Php 5,000 a week and repairman B is paid Php 4,200 a week. To minimize cost how many weeks should each of the two repairmen be employed?
