Detecting router cache snooping in Named Data Networking

Named Data Networking (NDN) is an example of studies that attempt to adapt the Internet architecture to new Internet usage patterns. To improve performance, named data is cached in NDN routers at different levels of the network hierarchy. However, caching data may be exploited to compromise consumer privacy using an attack called cache snooping. Cache snooping is the process of determining whether certain data are present on a given router cache and attribute that data to consumers. In this paper, we propose an approach to detect cache snooping attempts for low-level NDN routers.
