An Authenticated Encryption Based Security Framework for NoC Architectures

Abstract

Network on Chip (NoC) is an emerging solution to the existing scalability problems with SoC. However it is exposed to security threats like extraction of secret information from IP cores. In this paper we present an Authenticated Encryption (AE) based security framework for NoC based systems. The security framework resides in Network Interface (NI) of every secure IP core allowing secure communication among such IP cores. We simulated and implemented our framework using Verilog/VHDL modules on top of NoCem emulator. The results showed tolerable area overhead and did not affect the network performance apart from some initial latency.
