WebWe demonstrate a template that adversaries may use to construct covert timing channels through manipulating combinations of coherence states and data placement in different caches. ... Doroslovacki, M., Venkataramani, G.: DFS covert channels on multi-core platforms. In: Proceedings of IEEE International Conference on Very Large Scale ... 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.

Webment mechanism brings new covert and side channel vulnera-bilities to current multi-core and multi-processor platforms. It can be exploited to break down security protection mecha-nisms relying on resource partition and isolation, e.g., virtual machines (VMs). The revealed covert channel is based on two properties of the uncore power management ... WebFeb 14, 2024 · The way DFS works on your router is fairly simple.

WebAug 8, 2024 · Command and Control Infrastructure, also known as C2 or C&C, is the set of tools and techniques that attackers use to maintain communication with compromised devices following initial exploitation. The specific mechanisms vary greatly between attacks, but C2 generally consists of one or more covert communication channels between …
WebApr 18, 2016 · Modern multicore processors feature easily accessible temperature sensors that provide useful information for dynamic thermal management. These sensors were recently shown to be a potential security threat, since otherwise isolated applications can exploit them to establish a thermal covert channel and leak restricted information. … chiu harvardWeb2.We evaluate the proposed covert channels under the binary symmetric model. Results of our experiments are reported in Table 3. A discussion of our mem-ory controller-based covert channel against state-of-the-art covert is pro-vided. We also discuss potential mitigation strategies. Outline.

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. chiuer technology co. ltd
