1. 서론 현재 사용되고 있는 암호체계로는 RSA공개키 방식이 대표적이다. R. Rivest, A. Shamir, L. Adleman이 개발한 RSA공개키 암호체계[1]는 송신자가 공개키를 이용해 메시 지를 암호화 하고 수신자는 자신만이 알고 있는 비밀키를 이용해 평문화를 한다. 이 공개키 방식의 암호를 풀기 위 해서는 소인수분해를 해야 하는데 아무리 성능 좋은 컴퓨 터라도 큰 수의 소인수분해는 풀기 어려워 안전한 암호체 계다. 그러나 1990년대 중반, 벨연구소의 응용수학자 Peter Shor가 소인수분해를 쉽게 할 수 있는 양자알고리즘을 개 발했다[2], [3]. 이는 양자컴퓨터가 개발이 되면 지금의 공 개키 방식의 암호체계가 도청 위협에 직면했다는 것이다. 이 문제에 대한 대안으로 1983년 처음 Stephen Wiesner가 제안한 양자암호[4], [5]가 있다. 양자암호란 빛의 양자 역 학을 이용한 암호 체계이다. 이와 함께 Wiesner는 위조 불 가능한 화폐인 양자 화폐[6]를 구상했다. 양자 얽힘이라는 양자 역학적 특성을 이용한 양자 화폐는 최근 위조화폐로 문제가 되고 있는 부분에 대해 최적의 대응책으로 여겨지 고 있다. 본 논문에서는 양자암호...

In quantum key distribution (QKD), Alice selects a sequence of characters from a finite alphabet and transmits the corresponding signals, each described by a quantum state, to Bob. Between Alice and Bob, Eve---with her own receiver and transmitter---can eavesdrop. Eve is assumed to know beforehand all the possible states from among which Alice chooses. The central question is: Can Eve gain significant information about the key without influencing what Bob receives in ways that Alice and Bob can detect? This formulation implies that many options are available to Eve. It is the purpose here to d...
