Low-Cost Diaper Wetness Detection Using Hydrogel-Based RFID Tags

Minimalist Cryptography for Low-Cost RFID Tags

A radio-frequency identification (RFID) tag is a small, inexpensive microchip that emits an identifier in response to a query from a nearby reader. The price of these tags promises to drop to the range of $0.05 per unit in the next several years, offering a viable and powerful replacement for barcodes. The challenge in providing security for low-cost RFID tags is that they are computationally w...

Tamper Detection for Low Cost Rfid Tags: Using Watermarking with Chaotic Mapping

Low cost RFID tags pose unique security and privacy challenges. There is an unresolved issue however of data tampering. Here we propose a watermarking based tamper detection solution for low cost RFID tags where the Object Class (OC) and the Serial number (SN) field of an RFID tag are used as the cover medium. Additionally, the use of a chaotic map (i.e. Skew Tent Map) in the watermark embeddin...

Smart RFID Tag for Diaper Moisture Detection

An authentication protocol for low-cost RFID tags

Radio Frequency Identification (RFID) system can be read by radio wave within several metres without having direct contact. Many research focus on improving security and privacy problem. Recently, Rizomiliotis et al. point out that Song-Mitchell protocol is vulnerable to the denial of service attack, since the attacker can easily modify the data to make the server and the tag out of synchronisa...

Lightweight Authentication Protocol for Low-Cost RFID Tags

Providing security in low-cost RFID tags is a challenging task because tags are highly resource constrained and cannot support strong cryptography. Special lightweight algorithms and protocols need to be designed that take into account the limitations of the tags. In this paper, we propose a set of extremely lightweight tag authentication protocols. We also provide an analysis of the proposed p...
