Abstract:

Cache pollution attack is one of main security threats in named data networking. Focusing on low-rate cache pollution attack, the article proposed a collaborative detection mechanism. This mechanism calculates the request variability of every node in transmission path, adopts the request variability correlation between arbitrary middle node and network edge node as detection indicator. Simulations show that the mechanism can improve the detection rate, ensure the detection reliability. With appropriate collaborative nodes, it can detect locality-disruption more quickly. Compared with other typical detection methods, it is an effectively detection way for low-rate cache pollution attack.

Key words: named data networking, cache pollution attack, low-rate attack, collaborative detection
