Abstract

It is currently undergoing the fourth industrial revolution, which is the convergence of ICT and manufacturing, connecting both industrial equipment and production processes to one network and communicating with each other. The fact that they are connected to one network has the advantage of management, but there is a risk of security. In particular, Wi-Fi can be easily accessed by outsiders through a software change of the MAC address or password exposures. In this paper, by applying the method of Beacon using a Bluetooth Low Energy Add in Bluetooth 4.0, we propose a system of black-box approach to secure connections to wireless Internet, users do not have to know the password. We also implemented the proposed system using the raspberry pi and verified the effectiveness of a real-time system by testing the communication.

최근 부각되고 있는 4차 산업혁명 중의 하나의 경향은 ICT와 제조업의 융합으로 산업기기와 생산과정이 모두 하나의 네트워크로 연결되고 상호 소통하는 것이다. 하나의 네트워크로 연결되어 있다는 것은 관리의 이점이 존재하나, 역으로 보안의 위험성이 존재한다. 특히 Wi-Fi은 MAC주소의 소프트웨어적인 변경이나 비밀번호 노출을 통해 외부인이 손쉽게 접근이 가능하다. 따라서 본 논문에서는 Bluetooth 4.0에서 추가된 Bluetooth Low Energy를 사용하는 방식인 Beacon을 응용하여 사용자는 비밀번호를 몰라도 무선인터넷에 보안 연결하는 블랙박스 방식의 시스템을 제안한다. 또한 이 제안한 시스템을 실제로 라즈베리파이로 구현을 하고 실제 연결 테스트를 시행하여 시스템의 효용성을 검증한다.
