초록
ICT 기술이 발달하며 IoT 환경이 주목받고 있다. 하지만 IoT 디바이스는 다양한 사용 용도만큼 디바이스가 동작하는 CPU의 성능도 다양하지만, 인증에 필요한 암호화가 내장되지 않은 CPU를 사용하거나, 공개키 암호가 동작하지않는 디바이스도 다수 존재한다. 이에 따라, 본 논문에서는 램포트 해시체인, 램포트 서명, 블록체인을 분석하고, 기존인증 프로토콜 분석을 통해 인증, 무결성 및 부인 방지 기능을 제공하는 블록체인 기반 IoT 디바이스 인증 스킴을 제안하였다. 본 논문에서 제안하는 스킴은 IoT 디바이스에 단순 해시연산만을 요구하여 저성능 IoT 디바이스에서도 동작이가능해 IoT 환경에서 안전한 인증을 보장할 수 있다.
Abstract
With ICT technology develops, IoT environment is attracting attention. However, IoT devices have various CPU performance as much as various purpose of use. Some IoT devices use the cpu that doesn’t support public key cryptogrphy or crypto acceleration. In this paper, we study Blockchain-based IoT Device Authentication Scheme that provides authentication, integirity and non-repudation through analysis of Lamport Hash-chain, Lamport Signature, Blockchain and existing Authentication protocols. The proposed scheme requires only simple hash operation in IoT devices and it can operate in low performance IoT device, thus ensuring secure authentication in IoT environment.
