Current IP based network does not always efficiently deliver contents over IP based network even though large size contents greatly increase traffic volume of network. Content Centric Network (CCN) has been proposed as new network architecture to solve this problem. CCN directly use a content identifier to obtain content without a content location in the network. Then, the user has to get a content identifier before requesting the content but a way to get content information including a content identifier has not been well studied in CCN architecture. To solve this problem, we propose a content registration method for CCN routers with a blockchain technology to get content information in the architecture. We design and implement the content registration in CCN software platform Cefore and evaluated content information registration time.
