In a paper entitled "Chaffing and Winnowing: Confidentiality without
Encryption," Ron Rivest describes a method of transmitting a document
that gives an evesdropper no information about the content of the
document. <<http://theory.lcs.mit.edu/~rivest/chaffing.txt>
"Winnowing does not employ encryption, and so does not have
a``decryption key.'' Thus, the usual arguments in favor of
``keyrecovery'' don't apply very well for winnowing. As usual, the
policydebate about regulating technology ends up being obsoleted
bytechnological innovations. Trying to regulate confidentiality
byregulating encryption closes one door and leaves two
open(steganography and winnowing)."
