PhD Project: Reconfigurable Network on Chip Architecture Through Topology Obfuscation For Protecting SoC Against Reverse Engineering
Dipal Halder, Sandip Kumar Ray · 2024
Network-on-Chip (NoC) fabrics are widely used in modern System-on-Chip designs to provide coordination among integrated hardware units. A significant category of security flaws entails a rogue foundry manipulating the routing logic and NoC topology through reverse engineering. In this study, we develop an architecture to defend NoC fabrics against these kinds of attacks, called OBNoCs [1] which replaces router connections in a reconfigurable manner with switches that may be configured to induce the desired topology after manufacturing. We achieve verifiable redaction of NoC functionality with our approach: switch configurations create several permissible topologies, but only one of them is the desired topology. We implement the OBNoCs technique on the Intel QuartusTM Platform, and experimental findings on practical SoC designs demonstrate that the architecture has low overhead related to power consumption and resource usage.
