COMSEC has two presentations this week at the annual S&P conference. Blacksmith shows that all TRR mitigations deployed in (LP)DDR4 devices are vulnerable to non-uniform access patterns and ProTRR shows how one can build a space-refresh optimal in-DRAM TRR mitigation with principled security guarantees. We also have a paper called Spring at the co-located WOOT…

Our recent efforts in the area of DRAM Security resulted in the discovery of new non-uniform access patterns that can bypass all currently deployed TRR mitigations on recent (LP)DDR4 devices and revive Rowhammer attacks on new devices. Citing the paper: “after almost a decade of research and deployed in-DRAM mitigations, we are perhaps in a…

Together with Stefan Saroiu (Microsoft), we are organizing the first First Workshop on DRAM Security (DRAMSec) co-located with ISCA 2021. We have an excellent TPC representing industry and academic experts to bring you a very nice program including paper presentations, a keynote and a lively panel. If you are interested in the topic, please consider…
