Abstract

In this paper, we design a mutual authentication protocol which divided sessions from an authenticated session are updated periodically. And in order to minimize the traffic overhead for session authentication, we also introduce dynamic session management according to sampling rate of medical sensor type. And randomize the divided session time. This model has the effect of blocking the integrity and confidentiality intrusion of rogue gateway. Moreover, efficiency is provided through medical data to be transmitted have different sampling rate. In order to evaluate this model, it was embodied and experimented in TinyOS 2.1 environment. The result, we got an overall validity from three types of experiment.

본 연구에서는 센서와 게이트웨이간의 응용레벨 전송 세션을 세분화하고 각 세션을 주기적으로 갱신하는 기법을 적용하여 모델화하였다. 또한 이 모델에서의 인증을 위한 전송오버헤드를 최소화하기 위해 생체정보의 측정주기에 따른 동적인 유효 세션기법을 적용하였고 비인가 게이트웨이가 유효세션 시간을 예측하지 못하도록 유효세션 시간을 랜덤화 하였다. 이 모델은 비인가 센서기기의 무결성 침해와 기밀성 침해를 차단하는 효과가 있다. 본 모델의 평가를 위해 TinyOS 2.1 환경에서 구현하여 실험하였다. 따라서 전송할 생체정보가 서로 다른 측정주기를 갖는 것을 통해 효율성을 제공하도록 하였다. 결과적으로 제안한 기법을 3가지 실험을 통해 유효성을 확인하였다.
