The Pseudo Tag: Traffic Simulating of RFID Tags

摘要

The traffic analysis attack onto the RFID systems is an important threat to the application.As a countermove,the concept of "pseudo tag" is proposed in this paper.A pseudo tag is a device directly connected to the reader as a component It simulates the responses of ordinary tags when the reader scans.Since the generation of the pseudo streams is limited to the reader itself,only the reader could identify the output of the normal tags and that of the pseudo tag.We believe this approach could effectively garble the traffics generated by the system and thus could fight against the traffic analysis attacks.The implementation scheme for the pseudo tag is also provided in this paper.
