DH key exchange is a key exchange protocol that allows the sender and receiver to communicate over a public channel to establish a mutual secret without being transmitted over the internet. DH securely generates a unique session key for … WebRecall that we showed in class the following key claim. Claim 1 (Huﬀman’s Claim). There’s an optimal tree where the two smallest frequency symbols mark siblings (which are at the deepest level in the tree). We proved this via an exchange argument. Then, we went on to prove that Huﬀman’s coding is optimal by induction. jesus bless the children
