Multiprocessor Systems-on-Chip (MPSoCs) are pervading our lives, acquiring ever increasing relevance in a large number of applications, including even safety-critical ones. MPSoCs, are becoming increasingly complex and heterogeneous; the increased complexity as well as the networking approach in turn make security aspects more critical. In this work we propose and implement a hierarchical multi-agent approach providing solutions to secure Network-on-Chip based MPSoCs at different levels of design from nondeterministic attacks such as Denial-of-Service (DoS). We develop a flexible, scalable and modular structure integrating protection of different elements in the MPSoC (e.g. memory, processors) that can be tuned to particular attack scenarios - in this case a DoS attack. This work aims at providing a comprehensive, system-level protection strategy: this constitutes its main methodological contribution. We prove feasibility of the concepts via prototype realization in FPGA technology.
