Page 6: Authenticating the client

Page 6

  Authenticating the client
  The server must authenticate clients
  Depending on protocol, this may occur over crypto layer.  If so
  Authentication info can be stored on server
  In clear
  As one-way-hash (MD5, SHA-1, crypt(), etc)
  No need for challenge/response authentication
  Otherwise, authentication must be challenge/response based
  Authentication would need to be by pubkey-style auth, or
  PSK (preshared key) would need to be available on server
