The group data access control method in content centric network

Usage of the Internet for content delivery is increasing. Content Delivery Network is proposed for efficient content delivery in an IP network. However, there are some issues, including over load to content servers, and so on. Content Centric Network attracts attention as a new generation network, which can solve these issues. However, in Content Centric Network anyone who knows the content ID would get the contents, therefore, it is difficult to deliver content only to permitted person. To solve this problem, we propose the group data access control method. The proposed method is evaluated confidentiality, integrity and availability, and performance. The proposed method is also evaluated its action by emulation program.
