Network-on-Chip (NoC) has emerged as a promising solution for scalable communication among steadily growing number of cores integrated in MultiProcessor System-on-Chips (MPSoCs). The increasing system heterogeneity together with the possibility of reconfiguration makes the overall system security one of the major concerns in MPSoC design. On the other hand, modular and scalable design of NoCs enables their enhancements in various directions for supporting services other than simple data routing. In this work we propose a conceptual solution to secure NoC based MPSoCs at different levels of design. The basic idea is to integrate various kinds of security approaches from attack specific protection strategies up to system level security. The concept aims at securing single cores but also, at the same time, prevents potential propagation of the attack through the NoC towards. We prove feasibility via prototype realization in FPGA technology.
