Towards the application of flask security architecture to SoC design: work-in-progress

Abstract

In this work, we explore a security reference monitor (RM) design which borrows from the Flask security architecture. Our RM design goal is to achieve complete mediation by checking and verifying the authority and the authenticity of every access to every system object in systems-on-chip (SoCs). Access decisions are administered by a security logic "server" implemented as an extension of the peripheral bus. Initial results show a minimal increase in resource overhead and no significant impact on the performance.
