Communication availability in Networks-on-Chip (NoC) based Multi-processors System-on-Chip (MPSoCs) is being threatened by Denial of Service (DoS) attacks. We propose a novel distributed DoS diagnosis scheme which detects DoS attacks based on the performance degradation of sensitive flows. We explore the configuration parameters that assure a successful attack and demonstrate that a combination of two latency metrics can be leveraged not only for detecting a DoS attack, but also, aiming to locate the attack source, it identifies the router where the malicious traffic enters the sensitive communication path.     «
