Correct! Well done.
Incorrect.
The correct answer is B) A key exchange protocol allowing two parties to establish a shared secret over an insecure channel without prior shared secrets, based on discrete logarithm hardness
B
Correct Answer
A key exchange protocol allowing two parties to establish a shared secret over an insecure channel without prior shared secrets, based on discrete logarithm hardness
Explanation
DH allows A and B to compute the same shared secret without transmitting it. An eavesdropper sees only public values. ECDH uses elliptic curves for efficiency. Used in TLS for session key establishment.
