Abstract

Among U-healthcare services adapting the latest IT technique and medical technique, a body-injecting device technique providing medical service to a patient who has incurable disease. But the body-injecting device technique can be easily exposed during wireless section to the third person and it can be used illegally. This paper proposes certification protocol which certifies a patient and hospital staff using random number created by certification server and a patient with hospital staff by synchronization. Specially, the proposed protocol uses security information created by information registered in certification server previously by a patient and hospital staff so that in keeps from accessing of third person who didn't get approval. And it gives more stability.

최근 IT 기술과 의료기술이 접목된 유헬스케어 서비스 중 불치병을 갖고 있는 환자에게 의료서비스를 제공하는 체내삽입장치 기술이 각광을 받고 있다. 그러나 체내삽입장치 기술은 환자의 생체정보를 무선구간에서 제3자에게 쉽게 유출되어 악용될 수 있는 보안문제가 나타나고 있다. 본 논문에서는 환자와 병원관계자간 동기화를 통해 환자와 병원관계자가 서로 생성한 랜덤값과 인증서버가 생성한 랜덤값을 이용하여 환자와 병원관계자를 인증하는 인증프로토콜을 제안한다. 특히, 제안 프로토콜은 환자와 병원관계자가 사전에 인증서버에 등록된 정보를 이용하여 생성한 보안 정보를 세션키 생성과정에 이용함으로써 인증서버에게 허락 받지 못한 제3자의 접근을 차단함으로써 안정성을 높이고 있다.
