 - Add resistance to malicious MitM TCP segmentation if possible
 - Don't add significantly to CPU required for connection setup;
   if possible, reduce it significantly
-- Replace HMAC-MD5 with something more secure (see RFC 6151),
-  possibly HMAC-SHA256 or Poly1305 (see alternatives below).
+- Add message authentication (MAC), possibly HMAC-SHA256 or Poly1305
+  (see alternatives below), and remove Adler checksum
 - If possible, reduce the 4-message, two-round-trip handshake to
   a 3-message, one-round-trip handshake, as in SSU.
   This would require moving Bob's signature in message 4 to message 2.
