Group-Interest-Based Verifiable CCN

الملخص EN

To solve various problems of the Internet, content centric networking (CCN), one of information centric networking architectures (ICN), provides both an in-network content caching scheme and a built-in content verification scheme.

However, a user is still asked to generate many request messages when retrieving fragmented content through CCN.

This model can seriously increase the amount of network traffic.

Furthermore, when receiving content, a user is asked to verify the received content before using it.

This verification process can cause a serious service delay.

To improve such inefficiencies, this paper proposes a transmission process to handle request messages at one time.

Also, it suggests an efficient content verification method using both hash chains and Merkel-hash tree.
