Smartcard protocol sniffing
This talk will introduce you to the theoretical and practical issues involved in cloning/simulating existing smartcards. It is based on the lessons learned from cloning the Postcard (swiss debit card) issued by PostFinance.
After a brief introduction into the syntax of smartcard protocols (basically ISO 7816-4), the talk will demonstrate techniques to capture the communication between a smartcard and a terminal with the help of a Javacard-based logger cardlet. The gathered information (the semantics of the protocol) can then be used for cloning the smartcard under investigation.
