Abstract
A snooping invalidation module is implemented at the network interface for a given core, or processing element, of a multicore or manycore device, e.g., NoC device, to discard packets with invalid header flits (e.g., duplicate packets) from being injected into the device, e.g., by a malicious hardware trojan implemented in the network interface. In some embodiments, a data-snooping detection circuit is implemented to detect a source of an on-going attack.
