Information-Centric Networking (ICN) is an emerging networking technology that has been designed to directly operate on named content/information objects, rather than relying on the knowledge of the content location. According to the ICN principles, a user requests the information object by its name or some other form of object identiﬁer. After that, the ICN system is responsible for ﬁnding the particular object and send In git back to theuser. Despite a large number of works on ICN in recent years, ICN systems still face security challenges. This is especially true when considering different types of alternative networks, such as the wireless community networks (WCNs). In this work, we explore the applicability of ICN principles in the challenging and unpredictable environments of WCNs. We consider stateless contentdisseminationusingBloomﬁlters(BFs) and analyze two BF based approaches: the traditional single-stage BF and its generalization, the multi-stageBF. We fokus on the security aspects of BF based approaches and in particular on distributed denial of service (DDoS) attacks. Finally, we investigate the attaca probabilisty for various system and net work parameters, such as the number of hash functions, the BFmaximum ﬁll factor, and the number of hops toward the victim node.
