Title: Using the Generation One EPC RFID LockID Command as a Method of Directed Attack
Author(s): Christopher Mark Bolan
Keywords: RFID, Electronic Product Code, Deinal of Service
Abstract: An unlocked EPC tag allows for issuance of any command without the need for any authorisation with the exception aforementioned KILL command. This means that a system with unlocked tags would allow any attacker to modify tag data at will, whilst also opening the door to a range of other misuse. One possible avenue of active misuse against unlocked tags would be to issue LockID commands and ‘permanently’ lock some or all of a system‘s RFID tags. As this attack is simply an issuance of a valid command it fits firmly in the category of an active misuse and could also be considered a limited form of DoS as future valid commands would be ignored and limit or cripple the functionality of a system dependant on operation.
