1. Consider the following scenario: Two parties want to perform a key exchange using the Diffie-Hellman Key Exchange algorithm. They agree on a prime number

1. What is y₁, the number generated by the first party to send to the second party?

Answer

2. What is y₂, the number generated by the second party to send to the first party?

Answer

3. What is z, the key that resulted from their transaction of keys?

Answer

4. What can we say about the intermediary keys, y₁ and y₂?

The keys were the same. This possibility is important since we lose information and we're transmitting a secret over an insecure channel

The keys were different, but mathematically they could have been the same

The keys were different. It is necessary for the keys to be different if the initial secrets x₁ and x₂ are different

The keys were the same because the Diffie Hellman Key Exchange is extremely insecure and vulnerable to such errors

Consider the following scenario: Two parties want to perform a key exchange using the Diffie-Hellman Key Exchange algorithm. They agree on a prime number p=37, a base number g=7. The first party generates a key x1=22, and the second party generates a random key X2=13. 1. What is y, the number generated by the first party to send to the second party? 2. What is y2, the number generated by the second party to send to the first party? 3. What is z, the key that resulted from their transaction of keys? 4. What can we say about the intermediary keys, y1 and y2? The keys were The keys were the same. This different, but possibility is important since we lose mathematically information and we're transmitting they could have a secret over an insecure channel been the same The keys were different. It is the keys were the same necessary for the keys to be because the Diffie Hellman Key different if the initial secrets Exchange is extremely insecure X1 and 2 are different and vulnerable to such errors 1.
