Instruction Set Extensions for Cryptographic Hash Functions on a Microcontroller Architecture

Andreas Peter Burg, Jeremy Hugues-Felix Constantin

In this paper, we investigate the benefits of instruction set extensions (ISEs) on a 16-bit microcontroller architecture for software implementations of cryptographic hash functions, using the example of the five SHA-3 final round candidates. We identify t ...

A 500 fW/bit 14 fJ/bit-access 4kb Standard-Cell Based Sub-VT Memory in 65nm CMOS

Andreas Peter Burg, Pascal Andreas Meinerzhagen, Oskar Andersson

Ultra-low power (ULP) biomedical implants and sensor nodes typically require small memories of a few kb, while previous work on reliable subthreshold (sub-Vt) memories targets several hundreds of kb. Standard-cell based memories (SCMs) are a straightforwar ...

A First Step Towards Automatic Application of Power Analysis Countermeasures

Paolo Ienne, Francesco Regazzoni, Philip Brisk, Ali Galip Bayrak

In cryptography, side channel attacks, such as power analysis, attempt to uncover secret information from the physical implementation of cryptosystems rather than exploiting weaknesses in the cryptographic algorithms themselves. The design and implementati ...

A Modular Approach towards Wearable Computing

Xavier Righetti

Thanks to recent improvements in electronics, conductive materials and energy storage capabilities, we are now able to embed small circuits but also ultra-mobile PCs (UMPC) into clothes. These devices are able to sense, process and communicate information ...

High resolution miniature rotary microactuator

Jean-Marc Breguet, Walter Driesen

For the development of high precision mobile microrobots with a size of about one cm3, capable of micromanipulation tasks, small and precise actuators have to be developed in order to provide the microrobot and its manipulation tools with the required degr ...

128 channel PCI-based data acquisition system for MDSplus

Basil Duval, Xavier Llobet

With the increasing demand for analogue channel acquisition on the TCV tokamak, a new PCI based acquisition has been specified, designed, built and installed into our MDSplus acquisition environment. The design criteria were to not only improve the cost/ch ...

Decorrelated Fast Cipher: an AES candidate well suited for low cost smart cards applications

Serge Vaudenay

In response to the call for candidates issued by the National Institute for Standards and Technologies (the Advanced Encryption Standard project) the Ecole Normale Superieure proposed a candidate called DFC (Decorrelated Fast Cipher). DFC is based on a dec ...

Implementation of 8-bit Coded Character Sets in Ada

A general frame is proposed for implementing 8-bit coded character sets in Ada in conformance with current international standards. This frame is then applied to what is termed Latin alphabet No. 1 which covers Western European languages. Also shown is how ...
