Due to the tight cost and constrained resources of high-volume consumer devices such as RFID tags, smart cards and wireless sensor nodes, it is desirable to employ lightweight and specialized cryptographic primitives for many security applications. Motivated by the design of the well-known Enigma machine, we present a novel ultra-lightweight cryptographic algorithm, referred to as
Hummingbird
, for resource-constrained devices in this paper.
Hummingbird
can provide the designed security with small block size and is resistant to the most common attacks such as linear and differential cryptanalysis. Furthermore, we also present efficient software implementation of
Hummingbird
on the 8-bit microcontroller
ATmega128L
from Atmel and the 16-bit microcontroller
MSP430
from Texas Instruments, respectively. Our experimental results show that after a system initialization phase
Hummingbird
can achieve up to 147 and 4.7 times faster throughput for a size-optimized and a speed-optimized implementations, respectively, when compared to the state-of-the-art ultra-lightweight block cipher
