It is known that attacks at the Radio Frequency Identification (RFID) hardware layer modify the integrity of output data produced by an RFID system. This is a serious problem for business applications which use this data to make high value decisions on the authenticity of products such as authenticity of pharmaceuticals. We are currently undertaking research into ways intrusion detection, a branch of computer security, can be adapted to determine when attacks have occurred to prevent integrity loss from reaching the strategic layers of a business. Our approach considers how entities behave to indicate when they have been attacked. This overcomes the cost and functional hardware limitations which previous work has been constrained by. We envisage that our approach will have broad security relevance within RFID systems as RFID is expected to become more widespread in the future.
