Bob has a secret and Alice has the same secret. Why can’t they create a shared encryption key based on their secrets? Well, they can do this with Password Authentication Key Exchange (PAKE). So, let’s look at a simple method using discrete logs, and then we will convert it to elliptic curve methods. While discrete logs have been used in the past for Diffie-Hellman key exchange methods, we are increasing moving towards elliptic curve…
