Wouldn't winnowing and chaffing be worthless if your adversary had
access to the entire message stream.

Postulate: Given that Charles has access to all message traffic
between Bob and Alice, by recombination of packets with unique
serial numbers, and the ability to recognize the full message (which
would be easier with a packaged message) the problem reduces to finding
the combinatorial set of packets and testing each resulting 'message.'

Given the abilities of an even moderately powerful machine, it would
seem that unless the total chaff and wheat exceeded something on the
order of 100mbytes the message could be recovered in a relatively short
time.

What am I missing?
