최근 사물 인터넷의 핵심 프로토콜인 CoAP (Constrained Application Protocol)에 대한 활용도가 높아짐에 따라 관련 라이브러리가 등장하고 있으며 그 중 python을 기반으로한 CoAPthon은 개발이 용이한 장점 때문에 많은 관심을 받고 있다. 하지만, CoAPthon의 현재 구현 버전에는 자원 관찰과 블록 전송의 결합 기능이 올바르게 구현되어 있지 않다. 본 논문에서는 CoAPthon에 자원 관찰과 블록 전송의 결합 기능을 구현하고, Raspberry Pi 2에서 구현 내용을 실험하여 그 기능을 검증하였다.

Recently, interest and investment in the Internet of Things (IoT) have increased significantly, and security issues are constantly being raised. As a solution, the IETF ACE Working Group is establishing the ACE framework standard, which is a new security framework for various constrained IoT environments based on the existing OAuth 2.0. However, additional work is required to apply the ACE framework, which proposes a new lightweight security system, to the existing Internet environment, and this additional cost is a factor that hinders the application of OAuth 2.0 to the IOT environment. Therefore, we propose an IoT authentication framework based on OAuth 2.0's existing development motivation, and implement a proposal framework based on CoAPthon and analyze its performance.
