There is a company that provides a hardware based solution to this
problem. The products are called SafeNet that use encrypting modems and
encrypting LAN devices that would reside on the host. It requires the
remote user to insert a smart card and authentication pin that gets sent
back to the key management server then the keys get sent to the end user
and the protected server thus opening up a secure channel between the two
allowing for secure communications.
The three companies that do this that I know of are
You'll have to look at these to see which one would work with a
particular network topology...some support frame relay connections and
others a dedicated link only...but none of them support all of the
different configurations or topologies out there....being the down fall
for most of this technology...not to mention costs....
