We were excited to be nominated as one of four finalists for the Intel Hardware Security Academic Award for our work on BlockHammer, our state-of-the-art throttling-based RowHammer defense. We’d like to congratulate Abdullah Giray Yağlıkçı & team on their honorable mention amidst a very competitive field! The winners were announced in August here.
BlockHammer detects a RowHammer attack using area-efficient Bloomfilters and selectively throttles memory requests such that no row is activated rapidly enough to induce bit flips. BlockHammer prevents RowHammer attacks and reduces their negative impact on system performance.
