Access Control with Individual Key Delivery in ICN

Abstract (in Japanese) (See Japanese page) 
(in English) Information-Centric Networking (ICN), which transfers Interest by the name of content without using DNS (Domain Name System) and caches the response content from publishers on routers, is attracting attention as a network that efficiently delivers content such as IoT. There are two types of content: content that anyone can freely obtain and content that only limited users can obtain. When requesting content of the latter type, an access control for determining whether or not the requesting user can access is required. In the current Internet, user requests reach the authoritative DNS server of content providers, so access control is easily realized at the authoritative DNS server. However, in the ICN, it is difficult to control user access because content items are distributed at routers. As an access control method for ICN, a broadcast-based method has been proposed in which the content is encrypted, the key for decryption is changed periodically, and the key is distributed to all subscribing users. However, in this method, users who have lost the access right also have the unchanged key, so there is a problem that the content items can be obtained inadequately by users without access right until the next key is distributed. In this paper, we propose a method that enables access control at publishers by enabling the first Interest packet of content always to reach publishers. We derive the overhead delay of the proposed method by simple analytical model and show that the overhead delay is just several 10 ms to several 100 ms when the requesting rate to a publisher is smaller than 250 per second. Moreover, we show that the proposed method causes approximately 7GB of control traffic per day, while the broadcast-based method causes at least 250 GBytes of unauthorized traffic per day. Therefore, the proposed method can significantly reduce the amount of overhead traffic compared with the broadcast-based method.
