摘要
An improved MAC aggregation technique is disclosed that yields an aggregate MAC much shorter than the concatenation of constituent MACs while achieving improved resilience to denial-of-service (DoS) attacks. The aggregate MAC is constructed in a manner wherein upon instance of channel impairments or malicious attack (e.g., from a rogue node or man-in-the-middle attacker ), only a portion of the aggregate MAC will include corrupted data, at least a portion of the aggregate MAC thereby including valid verifiable data. A source of corruption of the aggregate MAC may be ascertained based on indicia of which constituent MACs are included in the valid portion; and constituent MACs that are wholly included in the valid portion may be declared valid.
