Low-cost mutual RFID authentication model using predefined password lists

Abstract

The use of RFID tags for storing unique identifiers increases the complexity of existing global supply chains. Companies participating in this RFID-aided supply chains are confronted with new challenges by using RFID technology. Most RFID tags contain no sophisticated data protection mechanisms, because they are primarily designed to be cheap and to carry a very limited amount of data. This lack of data protection introduces various attack scenarios for current and upcoming RFID scenarios. The use of authentication in communication networks prevents third parties to gather access to confidential data. We introduce a mutual authentication model prevent the exposure of RFID communication data between tag and reader based on the implementation of predefined on-tag password lists.
