Résumé

Recent works have demonstrated that it is possible to carry out side-channel attacks on SoC-FPGAs, internally and remotely, without any specialized equipment used in traditional side channel attacks. These advances have highlighted the vulnerability of FPGA-based systems. So far, one of the main limitations of this type of attacks is the problem of remotely determining a stable timing reference point for aligning the traces that correspond to the power consumption of the targeted module. Essentially, because there is no practical way to acquire a trigger signal directly from the architecture under attack since it is, usually, logically isolated. In this work, we propose a stable trigger mechanism based on a frequency-based covert channel, which can be leveraged to improve the feasibility of remote power attacks. We demonstrate this approach by performing a successful key recovery on a hardware implementation of AES-128.
