Covert Channels through Random Number Generator - Mechanisms, Capacity Estimation and Mitigations

Explore the mechanisms, capacity estimation, and mitigations of covert channels through random number generators in this conference talk presented at CCS 2016. Delve into the usage examples, the role of DCD instruction in creating covert channels, and theoretical estimations of channel capacity. Examine the impact of various factors such as latencies, GPU noise, and complex protocols on covert communication. Learn about potential software and hardware mitigation strategies to counter these security threats. Gain insights from the research conducted by Dmitry Evtyushkin and Dmitry Ponomarev from SUNY Binghamton, presented at the 23rd ACM Conference on Computer and Communications Security in Vienna, Austria.
