Résumé

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.
