In order to prevent the potential DoS attack against mapping cache under identifier-based universal network,this paper proposes an efficient defense approach based on double-threshold scheme.This approach not only designs a novel puzzle challenge mechanism based on iterative idea to decrease the growth rate of mapping entries,but also presents the trust value algorithm of mapping information to identify and filter out the malicious mapping entries.In particular,our analytical results show that,this approach is efficient and feasible to prevent the DoS attack against mapping cache,and resists the mapping cache overflow.
