Security Analysis of Niu et al. Authentication and Ownership Management Protocol

Over the past decade, besides authentication, ownership management protocols have been suggested to transfer or delegate the ownership of RFID tagged items. Recently, Niu et al. have proposed an authentication and ownership management protocol based on 16-bit pseudo random number generators and exclusive-or operations which both can be easily implemented on low-cost RFID passive tags in EPC global Class-1 Generation-2 standard. They claim that their protocol offers location and data privacy and also resists against desynchronization attack. In this paper, we analyze the security of their proposed authentication and ownership management protocol and show that the protocol is vulnerable to secret disclosure and desynchronization attacks. The complexity of most of the attacks are only two runs of the protocol and the success probability of the attacks are almost 1.
