SECURE MESSAGE TRANSMISSION APPARATUS AND PROCESSING METHOD THEREOF

摘要

The disclosure provides a secure message transmission apparatus and a processing method thereof. A method for processing a secure message may include receiving a message transmitted by a transmission-side terminal and determining whether the message is an encrypted message, by a non-secure message service unit; delivering the encrypted message to a secure message service unit by the non-secure message service unit when the message is the encrypted message; and decrypting the encrypted message, and re-encrypting the decrypted message and transmitting the re-encrypted message to a reception-side terminal, by the secure message service unit.

主权项

1. A transmission-side terminal comprising:
communication circuitry configured to transmit/receive an encrypted message; and a control unit comprising processing circuitry and having a secure domain and a non-secure domain, said secure domain being based on a secure operating system and said non-secure domain being based on a non-secure operating system, said secure domain and said non-secure domain being physically separated from each other, said processing circuitry configured to receive a message as input in the secure domain and to encrypt the received massage, and to deliver the encrypted message to the non-secure domain and to transmit the encrypted message to a message service apparatus through the communication circuitry.
