Vendor Gets Close To RFID Chip That Can’t Be Cloned
Written by Evan SchumanJanuary 7th, 2009
Can an RFID chip be made uncloneable? No, but one Palo Alto vendor is arguing that it’s gotten quite close.
The vendor’s position, according to this well-done NetworkWorld story, is to “create multiple PKI-like key pairs based on integrated circuit impurities so that a given chip will always respond to a particular stimulus in a predictable way. And, because it’s the impurities in the silicon that cause this effect, it’s impossible to create a chip that will respond to a specific stimulus.” For one possible future of RFID, it’s worth a read.
Cards issued by European banks when used online cross border don't usually support AVS checks. So, when a European card is used with a billing address that's in the US, an ecom merchant wouldn't necessarily know that the shipping zip code doesn't match the billing code.
