WebOur experiments on an Intel Xeon server platform demonstrate covert thermal channels that achieve up to 12.5 bps and weak thermal side channels that can detect processes executed on neighbouring cores. This work therefore shows a limitation in the isolation that can be achieved on existing multi-core systems. http://blog.dlink.com/dfs-faster-wi-fi-why-you-want-it/
WebJan 16, 2024 · Most modern multi-core CPUs are implemented in System-on-a-Chip (SoC), where CPU and integrated Graphics Processing Unit (iGPU) share physical memory and some microarchitectures. iGPUs provide horsepower required by computeintensive tasks, taking off CPU's heavy workload. These tasks include rendering graphics, executing … WebDFS covert channels on multi-core platforms Abstract: Covert channels provide a secret communication medium between two malicious processes to exfiltrate information stealthily that violates the security policy of a system. In this paper, we demonstrate a …
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" WebThe storage covert channels that indirectly write the infor-mation into shared resources and the timing covert channels that are designed based on the resource access time are two significant implementations of covert channels [3], [1]. The typical timing covert channels including those by cache [4], memory bus [5], shared memory [6], branch ...
