Summary:The present invention provides an MAC algorithm design method which efficiently copes with a sub channel. By using the method, provided is a concept for designing encryption and decryption, and authentication code generation and verification methods which efficiently cope with a sub channel. An MAC algorithm is designed by inserting a message or generating an authentication code. Encryption and decryption, and authentication code generation and verification are performed by using the designed MAC algorithm and a random block unit encryption or decryption algorithm. 본 발명에서는 부채널 대응을 효율적으로 할 수 있는 MAC 알고리즘 설계 방법을 제시하고, 이를 이용하여 부채널 대응에 효율적인 암호화, 복호화 및 인증 코드 생성과 검증 방법 설계 사상을 제시하였다.
