Lightweight devices like smart cards and RFID tags are at the core of novel emerging technologies in the information society. These devices must be cheap so as to permit their cost-effective massive manufacturing and deployment. Unfortunately, their low-cost limits their computational power. Other devices, like nodes of sensor networks suffer from an additional constraint, namely, their limited battery life.

Secure applications designed for these devices can not make use of classical cryptographic primitives designed for full-fledged computers. In this sense, research on low-cost cryptography is fundamental.

This workshop aims to be a forum for the presentation and discussion of current research on different topics related to low-cost cryptography, from cipher design to implementation details.

The 1st International Workshop on Lightweight Cryptography for Resource-Constrained Devices is co-located with the Financial Cryptography and Data Security 2010 conference.
