<p>The present invention relates to a security message transmitting system which is provided to safely transmit a message requiring security in a message service by using an isolation environment of a terminal device having a non-security area and a security area physically separated from each other; to a device therefor; and to a method for processing a security message thereof. The system comprises a service device and a receiver terminal device. The service device checks sender information of messages transmitted from a sender terminal device to the receiver terminal device, encodes a message including a specific sender information using a key generated based on terminal information of the receiver terminal device, and transmits the message. The receiver terminal device includes a non-security message processing module operated in the non-security area and a security message processing module operated in the security area, and decrypts, if a received message delivered from the service device is an encoded message, the received message by the security message processing module of the security area, which is physically separated from the non-security area run by a non-security operation system and independently operated by a security operation system, and outputs the decrypted message through the non-security message processing module in the non-security area.</p> |
