초록
사물인터넷에 대한 관심이 증가하면서 사물인터넷에 적합한 여러 보안 기술들이 연구되고 있다. 특히 디바이스 센서네트워크 영역에서는 사물인터넷의 특성상 저사양 디바이스의 사용이 증가하고 다양화되었다. 그러나 현재의 인증 기술등의 보안 기술을 저전력·저사양 디바이스에 그대로 적용하기에 어려움이 있고, 이로 인해 보안 위협도 증가하였다. 따라서 사물인터넷의 센서 네트워크 통신상의 엔티티간 인증 프로토콜이 연구되고 있다. 2014년 Porambage 등은 타원곡선 암호 알고리즘에 기반한 센서 네트워크 인증 프로토콜을 제안하여 사물인터넷 환경의 안전성을 향상하고자 하였지만, 취약성이 존재하였다. 이에 따라 본 논문에서는 Porambage 등이 제안한 타원곡선 암호 알고리즘 기반 인증 프로토콜의 취약성을 분석하고, 사물인터넷 환경에서 센서 네트워크에 대한 개선된 인증 프로토콜을 제안한다.
Abstract
Recently interest in Internet of Things(IoT) is increasing, and a variety of the security technologies that are suitable for Internet of Things has being studied. Especially sensor network area of the device is an increased using and diversified for a low specification devices because of characteristic of the Internet of Things. However, there is difficulty in directly applying the security technologies such as the current authentication technologies to a low specification device, so also increased security threats. Therefore, authentication protocol between entities on the sensor network communication in Internet of Things has being studied. In 2014, Porambage et al. suggested elliptic curve cryptography algorithm based on a sensor network authentication protocol for advance security of Internet of Things environment, but it is vulnerability exists. Accordingly, in this paper, we analyze the vulnerability in elliptic curve cryptography algorithm based on authentication protocol proposed by Porambage et al. and propose an improved authentication protocol for sensor networks in Internet of Things environment.
