Dfs covert channels on multi-core platforms
WebFeb 14, 2024 · The way DFS works on your router is fairly simple. While you’re using Wi-Fi, your router will check to see whether or not it can use that expanded range of 5GHz … 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 ...
Dfs covert channels on multi-core platforms

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. Web邱朋飞 Background——Covert Channel Attack An example——Banking application Possesses important information such as account, password, identification OS enforces security policies to ensure that it is isolated from other applications Data is only allowed to be transferred to the authenticated bank servers The attacker gains the secret …
Webcreate a covert channel between two execution contexts running onthe same core but within two different SMTthreads. We call this covert channel IccSMTcovert. 3) IChannels exploits Multi-Throttling-Cores to create a covert channel between two execution contexts runningon two different physical cores. We call this covert channel IccCoresCovert. Web2.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. The remainder of the paper is organized as follows.
WebMar 24, 2015 · Our experiments on an x86-based platform demonstrate covert thermal channels that achieve up to 12.5 bps and a weak side channel that can detect processes … 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. …
