Summary:The present invention relates to an encryption device for high-speed encryption authentication and a driving method of the device. According to an embodiment of the present invention, the encryption device for high-speed encryption authentication comprises: an interface unit which receives compressed data from a peripheral device and performs a communication setting operation for encrypting the received compressed data to transmit the same to the peripheral device; and an encryption unit which performs mutual authentication for encryption of the compressed data with the peripheral device when the setting operation is completed, and performs mutual authentication by inducting a key in a way which shares the same symmetric key obtained by using a random number generated by generating a private key value as the random number (ECDH). 본 발명은 고속 암호인증을 위한 암호화 장치 및 그 장치의 구동 방법에 관한 것으로서, 본 발명의 실시예에 따른 고속 암호인증을 위한 암호화 장치는, 주변장치로부터 압축 데이터를 수신하고, 수신한 압축 데이터를 암호화하여 주변장치로 전송하기 위한 통신 설정 동작을 수행하는 인터페이스부, 및 설정 동작이 완료되면 주변장치와 압축 데이터의 암호화를 위해 상호 인증을 수행하며, 개인키 값을 난수로 생성하여 상기 생성한 난수를 이용해 얻은 동일한 대칭키를 주변장치와 공유(ECDH)하는 방식으로 키(Key)를 유도해 상호 인증을 수행하는 암호화부를 포함할 수 있다.
