| A part of my research is to find if and how it is possible to use the failure analysis tools and methods for security purposes (and inversly). This presentation will describe the last results obtained with the use of the light emission technique to perform a new side channel methodology. Indeed, last year, during cryptarchi 2008, I presented the first results obtained with the light emission technique, based on the work of Mr.Martin Hlavac on a microcontroller. I introduced the possibility to apply those results on the security domain. From the cryptanalyst point of view, by using the light emission information regarding a specific cipher algorithm on a device we can identify secret sensible datas. About this, same kind of method was used on an unprotected FPGA; and I will show the possibilities offered by a partial functional analysis, which allows to possibly perform a light emission attack (DPA-like) to extract secret key about cipher algorithm. |
