Abstract

본 발명은 동적 분리 채널에서의 메시지 인증 코드 전송을 통한 위변조 검증 방법 및 시스템에 관한 것으로, 송신하고자 하는 메시지가 선택되면, 상기 메시지에 대응되는 제1 메시지 인증코드(Message Authentication Code:mac)를 생성하는 단계, 서로 상이한 통신 방식을 이용하는 다수의 통신 채널을 보안 채널과 메시지 전송 채널로 구분한 후, 상기 메시지와 상기 제1 메시지 인증코드를 분리 전송하는 단계, 상기 보안 채널과 메시지 전송 채널을 통해 분리 전송되는 상기 메시지와 상기 제1 메시지 인증코드를 수신하는 단계 및 상기 메시지에 대응되는 제2 메시지 인증 코드를 생성한 후 상기 제1 메시지 인증코드와 비교하고, 일치 여부에 따라 위변조 여부를 판단하는 단계를 포함한다.
