For 10 years Side Channel Analysis and its related attacks have been the primary focus in the field of smart cards. These cryptographic devices are built with the primary objective to resist tampering and guard secrets. While embedded systems often have a lower security profile, such attacks have also become a realistic threat to these devices. This talk explores the use and impact of Side Channel Analysis on embedded systems, and outlines the large set of countermeasures that are available to defend against side channel analysis. Further, the options for developers to mitigate the impact of such attacks will be examined.
