암호는 무엇일까요? 암호는 원하는 사람만 알 수 있도록 약속을 정해서 만든 신호나 부호입니다.
로마제국의 정치가였던 율리우스 카이사르는 평소 가족이나 친지들과 비밀통신을 할 때 암호를 즐겨 사용했다고 합니다. 카이사르의 암호는 1:1 대응관계를 갖는 함수로 나타낼 수 있습니다.
이것처럼 고대의 암호는 많습니다. 그 중 고대 그리스의 역사학자 플루타르크에 따르면 약 2,500년 전 그리스의 도시 국가였던 스파르타에서는 전쟁터에 나가있는 군대에 비밀메시지를 전할 때 암호를 사용했다고 합니다. 무적이었던 스파르타군이 최초로 사용한 암호는 바로 스키테일 이라는 암호입니다.
그러면 고대의 암호만 있을까요? 현대에서는 주민등록번호에도 암호가 숨어져 있습니다. 주민등록번호의 앞 여섯 자리는 생년월일입니다. 만약 누군가의 생일이 1998년 4월 10일이라면 앞자리는 980410이 되는 것이죠. 뒷 자리 번호 중 맨 앞의 1이나 3은 남자라는 뜻이고 여자의 경우 2나 4를 씁니다. 다음 뒷 자리 5개의 숫자는 시,군,동 등 행정구역의 번호 입니다. 그리고 맨 마지막에 있는 숫자, 바로 그 숫자가 주민등록번호의 열쇠가 되는 숫자 입니다.
만약 어떤 사람의 주민등록번호가 980410-210068♦ 라면 980410210068까지 적고 그 밑에 234567892345를 놓습니다.
9 8 0 4 1 0 2 1 0 0 6 8
2 3 4 5 6 7 8 9 2 3 4 5
그리고 위에 있는 수와 아래 있는 수를 각각 곱한 것을 모두 더합니다. 즉, 9×2+8×3+0×4+......이렇게 말이죠. 결과는 157이 됩니다. 그렇다면 157+♦=11의 배수가 되어야 합니다. ♦안의 숫자가 바로 맨 마지막에 넣는 숫자 입니다. 157보다 큰 수에서 11의 배수는 165이겠지요? 따라서 ♦안에 들어가야 할 수는 바로 8이 됩니다. 그러므로 이 사람의 주민등록번호는 980410-2100688입니다.
또다른 현대의 암호에는 국제표준도서번호인 ISBN(International Standard Book Number) 입니다. 전 세계에서 출판되는 모든 책은 그 책의 고유번호인 ISBN이 부여됩니다. ISBN에는 책을 출판한 국가, 발행인, 도서명 등의 정보가 담겨 있습니다. 그 중 마지막 숫자가 바로 열쇠가 되는 체크숫자로, 정확한 ISBN이 맞는지 여부를 확인할 수 있습니다.
|
ISBN의 체크숫자 정하는 방법 체크숫자는 앞에서부터 홀수 번째 자리에 있는 숫자들을 그대로 더하고, 짝수 번째 자리에 있는 숫자들은 3배하여 더한 전체의 합이 10의 배수가 되도록 정합니다. |
다음은 체크숫자가 손상된 ISBN입니다. 손상된 체크숫자를 구해 봅시다.
ISBN: 978-89-6832-227-♦
1. 먼저 홀수 번째 자리에 있는 숫자들을 더합니다. 9+8+9+8+2+2+♦=38+♦
2. 다음으로 짝수 번째 자리에 있는 숫자들의 3배의 합을 구합니다. (7+8+6+3+2+7)×3=33×3=99
3. 이 때 38+♦+99=137+♦는 10의 배수입니다.
♦는 0부터 9까지의 숫자 중 하나이므로, 137+♦가 10의 배수가 되려면 ♦=3이어야 합니다. 따라서 손상된 마지막 숫자는 3이 됩니다.
