Summary:The present invention suggests a design and implementation method for a white-box implement method, which can be efficiently implemented. The present invention suggests an idea for designing safe and efficient encryption and decryption and authentication code generation and verification methods in a white-box attach model by using the same. A cryptography operating method includes the steps of: performing encryption without applying white-box implementation; and generating a message authentication code by using the white-box implementation method. 본 발명에서는 효율적으로 구현할 수 있는 화이트 박스 구현 방식에 대한 설계 및 구현 방식을 제시하고, 이를 이용하여 화이트 박스 공격 모델에서 안전하면서도 효율적인 암호화, 복호화 및 인증 코드 생성과 검증 방법 설계 사상을 제시하였다.
