| Abstract(in English) | Information-centric networking (ICN), which doesn't forward content based on IP addresses as in the conventional Internet, but cache content in routers based on the name of the requested content and deliver it to the content requester (consumer), has got attention as a next-generation network. In ICN, although anyone can upload content as a publisher, the problem of content poisoning attack (CPA), which an attacker pretending to be a legitimate publisher uploads fake content under a real content name and degrades the cache functionality, has been pointed out. As a countermeasure against CPA, existing research has proposed a method that determines the legitimacy of content received by consumers using digital signatures with public keys, and alerts routers of unjustified content. However, it is difficult for the previous method to detect fake-CPA that matches a digital signature generated by a public key associated with the content. Especially, it is also difficult to take measures against spoofed fake-CPA, in which the staff of the certification authority (CA) that manages the public key colludes with the attacker to rewrite the legitimate publisher's public key to the attacker's and inject fake contents that pretends to be real and popular contents into the cache. In this paper, we propose a method to prevent spoofed fake-CPA by managing content names with IOTA, a distributed ledger technology that is difficult to tamper with registration data, when the content is uploaded by publishers. We also compare the search time and memory requirements of four search methods that search for content names managed in the ledger in the proposed method. As a result, we confirmed the trade-off between the search time and memory requirements. |
