Abstract

In recent years more and more security sensitive applications use passive smart devices such as contactless smart cards and RFID tags. Cost constraints imply a small hardware footprint of all components of a smart device. One particular problem of all passivesmart devices such as RFID tags and contactless smart cards are the harsh power constraints. On the other hand, activesmart devices have to minimize energyconsumption. Recently, many lightweight block ciphers have been published. In this paper we present three different architecture of the ultra-lightweight algorithm presentand highlight their suitability for both active and passive smart devices. Our implementation results of the serialized architecture require only 1000 GE. To the best of our knowledge this is the smallest hardware implementation of a cryptographic algorithm with a moderate security level.
