NVM has become a promising technology to partly replace SRAM as on-chip cache and reduce the gap between the core and cache. To take all advantages of NVM and SRAM, we propose a Hybrid Cache, constructing on-chip cache hierarchies with different technologies. As shown in article, hybrid cache performance and power consumption of Hybrid Cache have a large(More)
Network covert channel is a technology that transfers information secretly through the computer network. The length-based covert channel is one of the most popular covert channels. Most of the existing length-based schemes are vulnerable to detections due to the abnormal statistical features of the covert traffic. In this paper, a Skype-based length covert(More)
Flash-based solid state disks (SSDs) are replacing hard disk drives owing to its high performance and low energy consumption. For both high reliability and large capacity, redundant array of independent disks (RAID) is commonly used in storage system. In all flash arrays, the HDDs in RAID are substituted by SSDs and it gains improvements in bandwidth and(More)
