Improving Confidentiality Against Cache-based SCAs

چکیده
Side channels and covert channels can give untrusted applications access to the trusted and sensitive data in order to retrieve private information.. In this poster, we present a countermeasure called the Smartflush against cache-based Side Channel Attacks (SCAs). The Smartflush is a quick-patch countermeasure proposed to counter timing attacks that exploit inclusive caches in Intel’s x86 architecture. The proposed countermeasure is tested against recent attacks like Flush+Reload. Results show that it improves the confidentiality of data with minimum or no performance degradation.

Secure Cache Modeling for Measuring Side-channel Leakage
Side-channel attacks try to break a system’s confidentiality using physical information emitted from the targeted system. Such information is leaked out through cache side channels, which can exist in many parts of the system. Cache memories are a potential source of information leakage through side-channel attacks, many of which have been proposed. Meanwhile, different cache architectures have...
متن کاملSecure Real-Time Streaming Protocol (RTSP) for Hierarchical Proxy Caching
Proxies are commonly used to cache objects, especially multimedia objects, so that clients can enjoy better quality-of-service (QoS) guarantees such as smaller startup latency and lower loss rate. But the use of multimedia proxies increases the risk that data are exposed to unauthorized access by intruders. In this paper, we propose an enhancement of the Internet IETF’s Real-time Streaming Prot...
متن کاملImproving cache utilisation
Microprocessors have long employed caches to help hide the increasing latency of accessing main memory. The vast majority of previous research has focussed on increasing cache hit rates to improve cache performance, while lately decreasing power consumption has become an equally important issue. This thesis examines the lifetime of cache lines in the memory hierarchy, considering whether they a...
متن کاملReduction in Cache Memory Power Consumption based on Replacement Quantity
Today power consumption is considered to be one of the important issues. Therefore, its reduction plays a considerable role in developing systems. Previous studies have shown that approximately 50% of total power consumption is used in cache memories. There is a direct relationship between power consumption and replacement quantity made in cache. The less the number of replacements is, the less...
