Security handfree kit and security communication system and method using public key infrastructure

摘要

The present invention relates to a security communication system and method using a secure hands-free kit and the public key infrastructure, in particular, the present invention is a mode selection for designating a normal mode and secure mode, automatically or by specifying the normal mode and the secure mode to manual messenger phone having a button, converts the analog voice data into digital data, and converts the digital data supplied from the external to an analog audio data to output, and perform Internet communication and internet security communication; And IM, send voice data to be applied from the phone with the specified path, a driver for transmitting the applied speech data from the outside to the messenger phone, a shared key, and generates a symmetric key security program programmed to encryption / decryption of transmission / reception data and includes a PC made of a passenger module for the exchange of communication data with the other party, and the security program whether to check the status of the presence of the messenger phone, user setting state, and the receiving side MG verification module to enable secure communication, the crystals are verified MG for generating a shared key and the symmetric key module, encoding the audio data is applied through the driver a predetermined format or encoded from an external encode to decode the transmitted data / decoding module, encoding in the encoding / decoding module password using the symmetric key data of audio and video formats Chemistry and cancer of decoding the data of the encrypted transmission of audio and video formats on the other side / decryption module, encoding or packetizing the encrypted data, and the station for the packet data received from the external packetized packetizing / de to packetization module and transmitting the packetized data to the other party via the sender module and the Internet, and includes a transmission and reception module for receiving the packet data transmitted from the other party through the Internet and transmitter modules. Therefore, by, according to the present invention by using the encryption algorithm of the public key infrastructure scheme encryption / decryption of transmission / reception data, and 1: there is an effect that it is possible to perform a first secure communication.
