How is the secret key (K) calculated for User B in the ECDH Key Exchange Protocol?

a: By adding User B's private key to User A's public key. Explanation

Explanation

b: By multiplying User B's private key with a generator point on the elliptic curve (G). Explanation

Explanation

c: By subtracting User B's private key from a random number. Explanation

Explanation

d: By dividing User B's private key by a prime number (n). Explanation

Explanation

What does the shared secret key (K) represent in the ECDH Key Exchange Protocol?

a: User A's private key. Explanation

Explanation

b: User B's private key. Explanation

Explanation

c: A randomly generated value. Explanation

Explanation

d: A common secret known to both User A and User B. Explanation

Explanation

What role does the generator point (G) play in the ECDH Key Exchange Protocol?

a: It determines the size of the public keys. Explanation

Explanation

b: It is used to generate a random number for key derivation. Explanation

Explanation

c: It serves as the base point for elliptic curve operations. Explanation

Explanation

d: It specifies the prime number (n) used in key calculations. Explanation
