QKDN meets ICN: Efficient Secure In-Network Data Acquisition

With the advent of massive Internet of Things (IoT) applications, the demand for efficient and secure data communication has been increased. Quantum key distribution (QKD) and information-centric networking (ICN) can be considered promising approaches. However, because these approaches have been developed independently thus far, they impose problems in effectively meeting demand. In this paper, we propose a system architecture that combines the two networking technologies such that each problem can be compensated for in a sophisticated manner. Through comprehensive simulations, we demonstrate that the streamlined system brings about a significant synergistic effect especially in terms of the utilization efficiency of secure keys and the effectiveness of content delivery.
