Abstract

In quantum cryptographic communication based on quantum mechanics, each piece of information is loaded onto individual photons and transmitted. Therefore, it is impossible to eavesdrop on only a part, and even if an intruder illegally intercepts a photon and retransmits it to the recipient, it is impossible to send the same information to the photon by the principle of quantum duplication impossible. With the explosive increase of various network-based services, the security of the service is required to be guaranteed, and the establishment of a quantum cryptographic communication network and related services are being promoted in various forms. However, apart from the development of Quantum Key Distribution (QKD) technology, a lot of research is needed on how to provide network-level services using this. In this paper, based on the quantum encryption device, we propose an integrated data structure for transferring quantum keys between various quantum encryption communication network devices and realizing an encrypted transmission environment.

양자 역학을 기반으로 하는 양자암호통신에서는 각각의 정보를 개별적인 광자에 실어 전송하기 때문에 일부만 도청하는 것이 기본적으로 불가능하며, 침입자가 광자를 불법적으로 가로채 수신자에게 재전송을 하여도 양자 복제 불가능성 원리에 의해 같은 정보를 광자에 실어 보내는 것이 불가능하다. 한편 네트워크 기반 다양한 서비스의 폭발적 증대와 함께 해당 서비스의 보안성 보장이 필수적으로 요구되면서 양자암호 통신망의 구축 및 관련 서비스가 다양한 형태로 추진되고 있다. 그러나 양자키 분배(QKD: Quantum Key Distribution) 기술의 발전과는 별개로 이를 활용한 네트워크 구축 및 다양한 양자암호 기반 서비스 제공 방안에 관해서는 많은 연구가 필요한 상태이다. 본 논문에서는 양자암호 장치를 기반으로, 다양한 양자암호 통신망 장비 간에 양자키를 전달하고 암호화된 전송환경 구현을 위한 통합 데이터 구조를 제안하였다.
