A Novel Countermeasure to Resist Side Channel Attacks on FPGA Implementations
Side Channel Attacks (SCAs) have proven to be very effective in extracting information from algorithmically secure systems. Since, the earliest reports of attacks exploiting side channels such as power consumption, timing behavior and electromagnetic radiation etc., the countermeasures to resist such attacks have also been proposed. A variety of countermeasures resisting SCAs have been presented that continue to fade away as resistant attack techniques are developed. Field Programmable Gate Arrays (FPGAs) were originally thought to be resistant to such attacks because of some inherent characteristics. Later, they were also found to leak information over the side channels.
