When a secure component executes sensitive operations, the information carried by the power consumption can be used to recover secret information Many different techniques have been developped to recover this secret, but only few of them focus on the recovering of the executed code itself Indeed, the code knowledge acquired through this step of Simple Power Analysis (SPA) can help to identify implementation weaknesses and to improve further kinds of attacks In this paper we present a new approach improving the SPA based on a pattern recognition methodology, that can be used to automatically identify the processed instructions that leak through power consumption We firstly process a geometrical classification with chosen instructions to enable the automatic identification of any sequence of instructions Such an analysis is used to reverse general purpose code executions of a recent secure component.
