The chapter described how public key authentication is used for message-by-message authentication in digital signatures. However, public key authentication is widely used for initial authentication. Describe the processes that the supplicant and verifier would use if public key encryption were used in initial challenge–response authentication. Draw heavily on your understanding of digital signatures, but put this information in challenge– response context.
