RFID system security assessment methodology based on attack graph model

In order to effectively evaluate the security level of an applicable RFID system, researchers usually need to carry out a series of penetration test from the view of attackers. According to the extent of the attacker's effort, security level of the RFID system can be assessed by both qualitative and quantitative method. A new attack graph mechanism based on the characteristics of the RFID offensive and defensive attack strategy is proposed by analyzing the activities of existing RFID attacks. By analyzing the attack characteristics of different RFID systems, the proposed graph model can automatically evaluate the attack vulnerabilitie and dynamically predict the trend of attack effect in RFID system. By analyzing the attack instances on RFID UHF EPC C1 Gen2 protocol, the validity of the attack graph model is verified.
