Abstract

Secret communication has developed from analogue communication to digital one. Secret communication which is based on digital communication has been designed succeeding safety of one-time pad. One-time pad's safety is attributed to the security of secret key's mutual storage and mutual synchronization that is the key's interchange basis is one of the essential factors. This manuscript examines mathematical stability of BB84 algorithm which is one of the quantum cryptography system, and conducts transmission of quantum key. The created key suggests One-time Pad algorithm which interchanges ciphertext implemented AES's 64th round.

비밀통신의 발전은 아날로그 통신에서 디지털 통신으로 진보해 왔다. 디지털통신상의 비밀통신은 one-time pad의 안전성을 승계하여 주로 설계 되어 왔다. One-time pad의 안전성은 상호 보관하는 비밀키의 안전성에 기인하고 비밀키의 교환에 의한 상호 동기화가 가장 중요한 요소이다. 본 논문에서는 quantum cryptography system 중 BB84 알고리즘의 수학적 안전도를 살펴보고 이를 이용하여 양자 키 전송을 시행한다. 생성된 키는 개인의 각 단말에서 AES의 64번 라운드를 시행한 ciphertext을 상호 교환하는 One-time Pad 형 알고리즘을 제안한다.
