PURPOSE: An image device, a security memory card, and an authentication method thereof are provided to prevent data leakage in advance by mutually certifying an image device and a memory card. CONSTITUTION: A data storage part(350) stores data which is transferred from an image device. A key storage part(320) stores the device key of the image device and the memory key of a security memory card. The key storage part stores a first access message which includes at least one key among the device key and the memory key. A security data processing part(330) extracts the device key or the memory key by receiving a second access message which includes at least one key among the device key and the memory key from the image device. A memory control part(340) certifies the extracted device key, the memory key, or the device key which is saved in the key storage part. |
