As technology nodes are decreasing in size, their reliability is unfortunately decreasing. In our research, we look at security implications of these reliability problems in DRAM.
Our research shows that one of these wide-spread reliability problems, known as Rowhammer, is particularly dangerous in the hands of a capable attacker. With enough ability to massage memory, the security of a given computer system usually depends on a single bit of information. We further investigate the effectiveness of various deployed mitigations in various levels of software/hardware against DRAM problems and explore new solutions in places where existing ones fail.
