Yet Another Ultralightweight Authentication Protocol that is Broken

Gildas Avoine and Xavier Carpent

Abstract: Eghdamian and Samsudin published at ICIEIS 2011 an ultralightweight mutual authentication protocol that requires few bitwise operations. The simplicity of the design makes the protocol very suitable to low-cost RFID tags. However, we 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.
