Blocking-Resilient Communications in Information-Centric Networks Using Router Redirection
Hamid Mozaffari, Amir Houmansadr, Arun Venkataramani · 2019
Information-centric network (ICN) designs are susceptible to censorship especially packet filtering based on content names. Previous works on censorship circumvention in ICN either have high processing times or use proxies that can be blocked easily by the censoring agents. We design a new censorship circumvention approach for ICN using router redirection that enables a client in a censored region to retrieve blocked content from a censored destination without the censoring agent detecting the use of a censorship circumvention tool. We conduct ndnSIM-based simulation experiments showing that our approach is practical with only a modest end-to-end delay overhead.
