Abstract

Smart healthcare systems, a convergent industry based on information and communications technologies (ICT), has emerged from personal health management to remote medical treatment as a distinguished industry. The smart healthcare environment provides technology to deliver vital information, such as pulse rate, body temperature, health status, and so on, from wearable devices to the hospital network where the physician is located. However, since it deals with the patient's personal medical information, there is a security issue for personal information management, and the system may be vulnerable to cyber-attacks in wireless networks. Therefore, this study focuses on a key-development and device-management system to generate keys in the smart environment to safely manage devices. The protocol is designed to provide safe communications with the generated key and to manage the devices, as well as the generated key. The security level is analyzed against attack methods that may occur in a healthcare environment, and it was compared with existing key methods and coding capabilities. In the performance evaluation, we analyze the security against attacks occurring in a smart healthcare environment, and the security and efficiency of the existing key encryption method, and we confirmed an improvement of about 15%, compared to the existing cipher systems.

ICT기반의 융합산업인 스마트 헬스케어 시스템은 건강관리부터 원격진료 범위에 걸쳐 다양한 산업분야의 핵심 연구주제이다. 스마트 헬스케어 환경은 웨어러블 디바이스를 통하여 사용자의 심박 수, 체온, 건강상태 등과 같은 생체정보를 주치의가 있는 병원 네트워크로 전달하는 기술을 의미하며 환자의 다양한 데이터를 수집하고 복합적인 정보를 추론할 수 있는 기술은 스마트 헬스케어 기술의 핵심기술이라 할 수 있다. 그러나 환자에 대한 개인의 의료정보를 다루는 만큼 정보관리에 대한 보안위협이 있으며, 무선 네트워크 환경에서 발생하는 공격기법에 대해서 취약점이 발생할 수 있다. 그러므로 본 논문에서는 스마트 헬스케어 기반의 디바이스 접근제어를 위한 키를 생성 후 생성한 키를 활용하여 안전한 통신 프로토콜을 설계하여 스마트 헬스케어 시스템의 보안성을 강화하였다. 성능평가에서는 스마트 헬스케어 환경에서 발생하는 공격기법에 대해서 안전성 분석을 하고, 기존의 키 암호화 방식과의 보안성 및 효율성을 분석하여 기존의 암호화 방식 대비 대략 15% 향상된 수치를 확인할 수 있었다.
