Abstract

The Internet of Things (IoT), in which resource constrained devices communicate with each other, requires a lightweight security protocol. In this paper, we propose a new message authentication scheme using a hash tree for lightweight message authentication in the Datagram Transport Layer Security (DTLS) protocol. The proposed scheme provides lightweight secure operations compared with those of the DTLS protocol. Besides, it provides more suitable performance than the DTLS protocol for an IoT environment, thanks to the reduced use of message authentication code.

제한된 자원을 가지는 장비들이 서로 통신을 하는 사물인터넷 환경에서는 경량화된 보안 프로토콜이 요구된다. 본 논문은 DTLS 프로토콜의 메시지 인증 경량화를 위해 해시 트리를 이용한 새로운 메시지 인증 기법을 제안한다. 제안된 기법은 DTLS 프로토콜의 기본 동작에 비해 경량화된 보안 동작을 제공하며, 통신과정 중에서도 불필요한 메시지 인증 코드의 사용을 줄여 사물인터넷 환경에 더욱 적합한 성능을 나타낸다.
