[Newsletter des Horst Görtz Instituts]

Hallo,

im Rahmen des HGI Kolloquiums "Aktuelle Themen der IT-Sicherheit" wird am kommenden *Mittwoch* (!) der folgende Vortrag angeboten:

*Side-Channel Resistant Crypto for less than 2,300 GE*

Termin:
Mittwoch, den 3. März um  11.00 Uhr (*s.t.*)
Raum: IC 4/161

Interessierte sind herzlichst eingeladen!

Abstract:
A provably secure countermeasure against first order side-channel attacks has been proposed by Nikova et al. in 2006. We have implemented the lightweight block cipher PRESENT using the proposed countermeasure. For this purpose we had to decompose the S-box used in PRESENT and split it into three shares that fulfill the properties of the scheme presented by Nikova et al. in 2008. Our experimental results on real-world power traces show that this countermeasure provides additional security. Post-synthesis figures for an ASIC implementation require only 2,300 GE, which makes this implementation suitable for low-cost passive RFID-tags.
