Abstract

Technology involves a detector that identifies side-channel attacks between virtual machines. According to some examples, an interprocessor interrupt (IPI) rate of a first virtual machine (VM), a time stamp count (TSC) rate of a second virtual machine, and a cache miss ratio (CMR) of a third virtual machine may be monitored. Side-channel attacks can then be detected based on interprocessor interrupt rates, timestamp count rates, and cache miss ratios.

Description

Background technique [0001] This application is a national phase filing under 35 US.C. §371 of PCT Application Serial No. PCT / US13 / 73140 filed December 4, 2013. This PCT application is hereby incorporated by reference in its entirety. [0002] Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section. [0003] Cloud infrastructure providers can take advantage of economies of scale to provide dynamic and on-demand computing resources at a lower cost. Virtualization is one of the tools available to infrastructure providers to increase efficiency and enhance performance. Virtual machines (VMs) from multiple customers may share physical resources (such as servers). Shared resources can result in multiple mutually distrusting customers simultaneously sharing physical resources from the same provider. Customers may be aware of the shared nature o...
