초록

대칭형 암호알고리즘은 고속의 데이터 처리 및 구현상의 용이성 둥의 장점에도 불구하고 인증기능의 부재로 인하여 네트워크 환경에는 부적합하다. 그러므로 대칭형 암호알고리즘이 인증기능을 수행할 수 있도록 MAC와 MDC를 이용한 혼합형 인증알고리즘을 제안하였다. 제안된 알고리즘은 대칭형 암호알고리즘과 별개로 동작하는 것이 아니라 암호알고리즘 자체에 인증기능을 수행할 수 있도록 함으로서 보안이 확보된 통신채널의 범위를 넓힐 수 있도록 하였다.

Symmetric cryptographic algorithm is incongruent in network environment by absence of authencation in spite of advantage of easy etc. on data processing and implementation of high speed. Therefore, proposed merging style authentication algorithm that use MAC and MDC so that symmetric cryptographic algorithm can achieve authentication. Proposed algorithm made security can wide of secure communication channel as to achieve authentication to cryptographic algerian itself not that act independently of symmetric cryptographic algorithm.
