Applying the Flask Security Architecture to Secure SoC Design

Abstract

We explore a 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 authenticity of every access to every system object. 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.
