Now let¡¯s look at cache pollution.
The attacker manipulates request distributions so caches fill with low-reuse objects, pushing out popular content. In NRS-based ICN, this is tightly coupled to the resolution–cache loop: when cache hit ratio drops, more requests need resolution and producer access, which increases NRS load and control-plane work, exacerbating latency and churn.
Typical vectors include:
Long-tail or random requests, which generate high-entropy name distributions so caches are constantly refreshed.
Similar-name occupation, where names look syntactically close to popular ones but map to useless content.
Dynamic naming, where frequent name changes prevent reuse even for logically identical content.
So, in short: cache pollution is not just a cache issue—it amplifies NRS and control-plane stress. |
