From NoC security analysis to design solutions

Abstract

This paper addresses a new kind of security vulnerable spots introduced by network-on-chip (NoC) use in system-on-chip (SoC) design. This study is based on the experience of a CAD framework for NoC design and proposes a classification of weaknesses with regard to usual routing and interface techniques. Finally design strategies are proposed and a new path routing technique (SCP) is introduced with the aim to enforce security.
