Question

Diffe-Hellman Key Exchange occurs in what steps?

Answer 1

The Diffie-Hellman Key Exchange algorithm consists of several steps: agreeing on a shared prime number and base, privately choosing random numbers, computing and exchanging public keys, and independently computing the shared secret key.

Step-by-step explanation:

The Diffie-Hellman Key Exchange algorithm consists of the following steps:

1. Both parties agree on a shared prime number, p, and a base, g.
2. Each party privately chooses a random number, a and b, respectively.
3. Both parties compute and exchange their respective public keys:

• Party A computes A = g^a mod p and sends it to Party B.
• Party B computes B = g^b mod p and sends it to Party A.

Both parties independently compute the shared secret key:

• Party A computes s = B^a mod p.
• Party B computes s = A^b mod p.

Both parties now have the same secret key, s, which can be used for secure communication.
