Abstract : Current cache side-channel attacks (SCAs) countermeasures have not been designed for many-core architectures and need to be revisited in order to be practical for these new technologies. Spatial isolation of resources for sensitive applications has been proposed taking advantage of the large number of resources offered by these architectures. This solution avoids cache sharing with sensitive processes. Consequently, their cache activity cannot be monitored and cache SCA cannot be performed. This work focuses on the implementation of this technique in order to minimize the induced performance overhead. Different strategies for the management of isolated secure zones are implemented and compared. CCS Concepts: •Security and privacy → Domain-specific security and privacy architectures;
