Yet Another Ultralightweight Authentication Protocol That Is Broken

Eghdamian and Samsudin published at ICIEIS 2011 an ultralight-weight mutual authentication protocol that requires few bitwise operations. The simplicity of the design makes the protocol very suitable to low-cost RFID tags. However, the authors demonstrate in this paper that the long-term key shared by the reader and the tag can be recovered by an adversary with a few eavesdropped sessions only. The market pressure to lower the price of tags is such that it has become a major topic of research to design an RFID protocol requiring very few gates and little computational power on the tag side.
