Thermal Covert Channels on Multi-core Platforms

WebCache timing channel can be combined with speculative instructions to launch powerful attack which enable the spy to read secret values of the kernel or other processes. Software layers in the computing stack cannot fully eliminate cache timing channels since caches are typically shared between multiple processes. WebFigure 4: Covert communication using Thermal Channels. We demonstrate that the temperature sensors on commodity multi-core platforms can be misused for covert communication by two colluding processes in spatially and temporally isolated systems. - "Thermal Covert Channels on Multi-core Platforms" rc car wheel pin

Webside channels. Speciﬁcally, we show that the processor core temperature can be used both as a side channel as well as a covert communication channel even when the system implements strong spatial and temporal partition-ing. Our experiments on an x86-based platform demon-strate covert thermal channels that achieve up to 12.5 bps WebDFS Covert Channels on Multi-Core Platforms Conference Paper Overview ... WebSuch dependency implies a covert channel threat in multi-core platforms. Specifically, the power status of the uncore reflects the workload pattern of the active core, and it can be probed by any process running on the processor. This allows the process to infer the workload information of the active core. sims 4 more toddler interactions mod
