This paper presents a first solution for NoC-based communication security. Our proposal is based on simple network interfaces implementing distributed security rule checking and a separation between security and application channels. We detail a four- step security policy and show how, with usual NOC techniques, a designer can protect a reconfigurable SOC against attacks that result in abnormal communication behaviors. We introduce a new kind of relative and self-complemented street-sign routing adapted to path-based IP identification and reconfigurable architectures needs. Our approach is illustrated with a synthetic set-top box, we also show how to transform a real-life bus-based security solution to match our NOC-based architecture
