Re: Some stuff about Diffie-Hellman (and more :-)

>What you say seems to indicate that D-H as we know and >love it has been rendered obsolete because it depends on the modulus >being known. What am I missing? DH exchange doesn't require a known modulus. Most people implement it with a common alpha and small set of generators so that they don't have to invent a distribution or agreement protocol. Authenticated DH exchanges (e.g., station-to-station protocol) can include these parameters as part of each parties signature; and provide an agreement policy (e.g., initiator's parameters unless receiver thinks they are weak). After each party has generated and exchanged an exponent, each verifies the `certificate' of the other, and the signature of the other over the exponent pair. The shared knowledge that makes this possible in this case is, of course, foreknowledge of the public key of the other party. If you don't know it before you start the protocol, you can't really know who you're talking to. Other protocols can be designed with other choices of shared knowledge. STS is immently practical, any other practical and fair scheme is likely to be similar, i.e., involve shared knowledge, independently generated random input from both parties, a mechanism for securely (but expensively) transmitting the random data (typically based on the shared knowledge), combining the disjoint random data symmetrically so that each party shares in a fresh secret session key, and finally authentication based in part on the original shared knowledge.

Several people have sent orders to me without including an e-mail address. This is not a problem, but I would like to confirm the orders so you know they were recieved. If you know this is you, or think it may be you, please send me a note. This is also the last call for orders. We will be taking orders until the 15th of February, so if you want one, send it ASAP. We will not be re-pressing the shirts, it is a one-time deal. Ordering information can be obtained via anonymous FTP to netcom.com: ~/pub/cvoid/cypherpunks/ordering.information.txt Christian Void /T71 | "I don't like it, and I'm sorry I | V/M/Research, Inc. cvoid(a)netcom.com | ever had anything to do with it." | P.O.

This protocol is an attempt to foil the man-in-the-middle attack. The protocol does not provide a %100 guarantee against man-in-middle, but it does make it much harder (or so says the book). Perhaps Robert's device really uses a variation of the Interlock Protocol, and not Diffie-Hellman (mentioned only as a red herring?). <shrug> Jim_Miller(a)suite.com

I support HR 3627
by W. Kinney 17 Dec '03

17 Dec '03

-----BEGIN PGP SIGNED MESSAGE----- Add my name to the list of supporters of HR 3627. The truly appealing thing about cryptography is that it places enforcement of the Fourth Amendment completely in the hands of citizens, regardless of the wishes of a sometimes hostile government. We should be exporting the Fourth Amendment far and wide. I wish technology could accomplish that for all ten in the Bill of Rights. -- Will Kinney -----BEGIN PGP SIGNATURE----- Version: 2.3 iQCVAgUBLVgn6vfv4TpIg2PxAQH+zgP9Eh8f1J66Tz7KwdIlfb5NxV1r1KvYA5e8 4yzzI/8tAlcjQ0irvCd3bHmIyQrjWRgrT3RgKV3L0TdLZCH8acY8bW3ioCLkZbUC aCbKETesIf80iGDIDnVYQCXf+HoNOyRJ15k2ytaGuutb1GthN9yG0r0zKfH8IkLW BemWKUWzS68= =ax1M -----END PGP SIGNATURE-----
