[p2p-hackers] amicima's MFP - preannouncement

[Alex Pankratov]

Matthew,

I can't seem to find the mentioning of replay protection in your
protocol. Also encrypted packets don't seem to carry any sort of
HMAC, which is also a bit odd. Perhaps these details are just
missing from the spec, in which case it might make sense to
produce a separate security-oriented description of the protocol.
