           Performance Analysis of Contemporary Light-Weight
               Block Ciphers on 8-bit Microcontrollers

This work presents a performance analysis of software implementations of
ciphers that are especially designed for the domain of ubiquitous
computing. The analysis focuses on the special properties of embedded
devices that need to be taken into account like cost (given by memory
consumption) and energy needs. The discussed ciphers include DESL, HIGHT,
SEA, and TEA/XTEA. Assembler implementations of the ciphers for an 8-bit
AVR microcontroller platform were analyzed and compared with a
byte-oriented AES implementation. While all ciphers fail to outperform
AES on the discussed 8-bit platform, TEA/XTEA and SEA at least consume
significantly less memory than the AES.
