WebFeb 28, 2024 · The steps needed for the Diffie-Hellman key exchange are as follows: Step 1: You choose a prime number q and select a primitive root of q as α. To be a primitive … WebThese questions revolve around DH and ECDH vs DHE and ECDHE.Specifically within the context of TLS/SSL. There are three questions in total (and a fourth bonus question). The goal of using Diffie-hellman at all in TLS/SSL is to avoid the case where the contents of the certificate are the sole source for seed value for generating symmetric keys.
