This is a follow up of a recent post: Passport News.
We have further information on the epassport issue covered recently. One of my questions seems to be answered already. Will passport chips remain silent if invalid keys are transmitted? There are rumors that chips won't remain silent. They will transmit their 'probably unique' serial number during handshake with any scanning device. This would mean that basic attacks like 'nation guessing' or 'does she carry a rfid passport' might be possible. 'Most wanted broadcasts' might be possible as well, because serialnumber->individual maps are inherent.
This is not the way it should be done. Bad medicine. What's the range within scanning is possible?
