Radio frequency identification (RFID) is a technology for automatic object identification. It has wide applications in many areas such as manufacturing, transportation, healthcare, and so on. However, many RFID systems are suffering from security issues. In this paper, we present an implementation of a secure UHF RFID tag baseband with a Hummingbird (HB) cryptographic engine using the SMIC 0.13µm...
This paper presents a practical implementation of a digital baseband for a low-cost UHF Radio Frequency Identification (RFID) tag, in which a cryptography engine based on International Data Encryption Algorithm (IDEA) primitive is embedded. A mutual authentication scheme enforced by the IDEA engine is proposed. The scheme can improve the security of the ISO 18000-6C protocol and meet the timing constraints...
Hummingbird algorithm is a newly proposed lightweight cryptographic algorithm targeted for low-cost RFID tag. In this paper, we present a hardware implementation of this algorithm using SMIC0.13 μm CMOS process. Methods are used to reduce the unnecessary clock toggling and data toggling to reduce dynamic power. Simulation results show that the total area of our design is 14,735 μm2. It requires 16...
