PKI (Public Key Infrastructure) can be used to authenticate both sides in computer network communication. We assume Alice needs to communicate with Bob over the Internet. But Alice needs to know if she communicates with Bob, and the same for Bob. We also assume Alice's public key is 'P-a', and her private key is 'S-a'. Bob's public key is 'P-b', and his private key is 'S-b'. Suppose Bob and Alice know their public keys each other. Please design a scheme using their public and private keys only to authenticate each other.
