Dfs 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. WebWe implement this covert channel both in a single threaded and simultaneous multi-threading (SMT) environment and show the feasibility of such a communication. Our …

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 ... WebAbstract. Designing software for multicore platforms is a significant challenge, as one has to break-down the work into items that can run in parallel. In this chapter we address the …
