Our well-known Web surfers, Bob and Alice, have access to a public key system that makes their public keys available to each other. Each knows their own private key. Suppose Bob has a document, m, that he wants to digitally sign. How does he do so? 1. Efficiency is not a concern here, any digital signature technique is fine. 2. What does Alice do to verify Bob’s digital signature
