Hummingbird is a recently proposed ultra-lightweight cryptographic algorithm targeted for resource constrained devices like RFID tags, smart cards and wireless sensor nodes. In this paper, the authors describe efficient hardware implementations of a stand-alone Hummingbird component in Field-Programmable Gate Array (FPGA) devices. They implement an encryption only core and an encryption/decryption core on the low-cost Xilinx FPGA series Spartan-3 and compare their results with other reported lightweight block cipher implementations on the same series. Moreover, a speed-optimized and an area optimized hardware architectures are also proposed in this contribution.
