Abstract

As natural language processing technology using machine learning develops, a Smart Home Network Service (SHNS) is drawing attention again. However, it is difficult to apply a standardized authentication scheme for SHNS because of the diversity of components and the variability of users. Blockchain is proposed for data authentication in a distributed environment. But there is a limit to applying it to SHNS due to the computational overhead required when implementing a proof-of-work system. In this paper, a lightweight work proof system is proposed. The proposed lightweight proof-of-work system is proposed to manage block generation by controlling the work authority of the device. In addition, this paper proposes an access control scheme for SHNS.

기계학습을 이용한 자연어처리 기술이 발전하면서 SHNS (Smart Home Network Service)가 다시 주목받고 있다. 그러나 SHNS는 구성 기기의 다양성과 사용자의 가변성 등으로 인하여 표준화된 인증 시스템 적용이 어렵다. 블록체인은 분산 환경에서 데이터 인증을 위한 기술로 제안되고 있지만, 작업증명시스템 구현 시 요구되는 계산 오버헤드 때문에 SHNS에 적용하는데 한계가 있다. 본 논문에서는 경량화된 작업증명시스템을 제안하였다. 제안하는 경량화된 작업증명시스템은 기기의 작업 권한을 제어함으로써 블록 생성을 관리하도록 제안되었다. 또한 본 논문에서는 이를 기반으로 SHNS의 접근통제 방안을 제안한다.
