COMMUNICATION SECURITY SYSTEM AND METHOD

摘要

A communication security system includes a secure communication application module and a chip module. The communication security system is installed in a mobile device. Accordingly, the communication security system of the present invention allows mobile devices of users to encrypt and decrypt communication data between the users. A communication security method includes the steps of generating keys, requesting a key exchange by a first mobile device, receiving a key exchange by a second mobile device, receiving a key exchange by the first mobile device, activating a key by the second mobile device, activating a key by the first mobile device, and starting secure communication between the first and second devices. Thus, the encrypted communication can avoid theft and unauthorized falsification.

主权项

1. A communication security system for a mobile device, comprising:
a secure communication application module having at least one application program interface (API) for providing a user interface and for transmitting communication data; and a chip module having a secure digital encryptor for performing key processing for the communication security system and for encrypting/decrypting the communication data; wherein the secure communication application module is able to transmit the communication data to the chip module, and the chip module encrypts/decrypts the communication data and returns the encrypted/decrypted communication data to the secure communication application module after the chip module receives the communication data.
