Abstract (in Japanese) (See Japanese page) 
(in English) While the widespread adoption of the Internet of Things (IoT) has enabled network connectivity for diverse devices, challenges remain in establishing external communication across NAT-separated environments and ensuring privacy through data confidentiality. This paper proposes a secure IoT remote control system that integrates DNS and Port Control Protocol (PCP) to address these issues. We design and implement the proposed system, and verify that the proposed system operates as expected through functional evaluation in a virtual environment.
