In this work, we propose a NoC which enforces the encapsulation of sensitive traffic inside the asymmetrical security zones while using minimal and non-minimal paths. The NoC routes guarantee that the sensitive traffic is communicated only through the trusted nodes which belong to the security zone. As the shape of the zones may change during operation, the sensitive traffic must be routed through low-risk paths. We test our proposal and we show that our solution can be an efficient and scalable alternative for enforce the data protection inside the MPSoC.
