DRAM latencies are inherently variable, potentially allowing a denial-of-service hardware Trojan (DoS HT) to degrade memory performance without becoming immediately obvious. This paper addresses the challenge of detecting a DoS HT that may have been inserted into a DRAM-based memory system, without requiring detailed internal knowledge of the DRAM device. We present a real-time machine-learning based DoS HT detection technique based on a low-cost hardware monitor at the interface to the DRAM controller, coupled with periodic software based analysis of monitoring output.
