Information Security Officer Interview Question:

Explain what's the difference between Diffie-Hellman and RSA?

Submitted by: Muhammad

Diffie-Hellman is a key-exchange protocol, and RSA is an encryption/signing protocol. If they get that far, make sure they can elaborate on the actual difference, which is that one requires you to have key material beforehand (RSA), while the other does not (DH). Blank stares are undesirable.
