walk*bound writes "In an essay published by ZDNet, security scientist Dan Geer has an interesting proposal to trust the handshake between e-commerce sites and zombie computers. The suggestion is simple: Assume end users either always say "Yes" or "No" to security dialog boxes, then make the decision two ways: "When the user connects, ask whether they would like to use your extra special secure connection. If they say "Yes," then you presume that they always say Yes and thus they are so likely to be infected that you must not shake hands with them without some latex between you and them. In other words, you should immediately 0wn their machine for the duration of the transaction — by, say, stealing their keyboard away from their OS and attaching it to a special encrypting network stack all of which you make possible by sending a small, use-once rootkit down the wire at login time, just after they say "Yes.""
