Abstract

As fusing IT and medical technique, the number of patients who adhere medical equipment inside of them is increasing. However there is a problem of for the third person to tap or modulate the patient's biometric data viciously. This paper suggests quantum encryption-based key distribution model to share key for the third person not to tap or modulate the patient's biometric data between patient and hospital staff. The proposed model uses one-time pad key that shares key sending random bits not direct sending message of quantum data. Also, it guarantees patient's anonymity because the biometric data of injected-device in the body doesn't be exposed unnecessarily.

IT 기술과 의료기술이 융합되면서 환자의 체내에 의료장비를 부착한 환자의 수가 증가하고 있다. 그러나 환자의 생체정보를 제 3자가 악의적으로 도청 및 변경하는 문제점이 발생하고 있다. 본 논문에서는 환자와 병원관계자 사이에서 환자의 생체정보를 제3자가 도청하거나 변조없이 키를 공유하도록 양자 암호 기반의 키 분배 모델을 제안한다. 제안 모델의 양자 정보는 메시지 직접전달보다는 임의의 비트들을 전달하여 키를 공유하는 one-time pad 키를 사용한다. 또한, 제안 모델은 체내삽입장치의 생체정보가 제3자에게 불필요하게 노출되지 않아 환자의 익명성을 보장받는다.
