Name _________________________ Score: ___ / 14 CPSC 42500 Homework 7 addendum: Diffie-Hellman Key Exchange 1. (2 pts) Give two different ways to simplify the expression (32)4 and show that they are equal. 2. Pretend you are Alice and have agreed with Bob to carry out Diffie-Hellman key exchange with parameters p = 23 and g = 5. You may use a calculator to answer the following, but write down and label all the quantities you use. a. (2 pts) Assume you choose the secret random value x = 19. Compute the value gx (mod p) that you will send to Bob. b. (2 pts) In the protocol, you receive the value gy = 18 from Bob. Compute your shared secret value. c. (4 pts) Now pretend you are an eavesdropping adversary. From g, p and gy, find Bob’s secret y (it’s possible!) d. (4 pts) Describe how you found the value in part (c), and comment on how this reflects the security of Diffie-Hellman key exchange. Page 1 of 1

Diffie-Hellman Key Exchange
Diffie-Hellman is the common algorithm that helps encrypt communication between the
client and the server. With this knowledge, conversing parties can generate private keys simply
from the exchange of public information. This makes it difficult for external parties with
knowledge of public information to access the communication details. Perhaps it would be more
meaningful to describe keys for a better understanding of the information. Keys are a set of data
information coded in a way that allows encryption and decryption of data. Keys are components
of cryptographic algorithms.
Being a component of cryptographic algorithms, keys are crucial in encryption and
decryption, without which data is vulnerable to atta...
