In fact the system used by the major Dutch banks is audited rather extensively. The OTP system is based on an external smartcard reader and a smartcard application on the bank card. They have no physical connection so the web interfcae will present you with a challenge and you must use that challeng, your card and your pin to generate the proper response. Then you have to type in this response.
What is included in the "signed" stuff, and when is that challenge/response done? If malware is running on the user's computer, can it change the destination of a funds transfer invisibly to the user, and still have the verification work? That is, user enters "Pay 100 to Credit Card". The malware sends the bank "Pay 100 to Bad Guy". The bank tells the user "Verify transfer of 100 from your account". Oops. Seth
