Abstract:

Hummingbird encryption algorithm is a lightweight encryption algorithm for RFID tags and other hardware limited system.The Hummingbird algorithm has been verified on different platforms.The paper proposes a Hummingbird algorithm architectures,which requires less hardware resources than the other methods with the the same response time.It uses a low-end Xilinx Spartan-3 FPGA chip as the verification platform.Experimental results show that this architecture can be preferably embedded into the hardware constrained systems,especially in embedded systems.
