Apparatus and method for implementing data safety transmission of mobile communication apparatus

Abstract

This invention discloses a safety transmitting device and a method for mobile communication devices. Said device can be connected on radio mobile communication devices of GSM or CDMA network detachably via their interface units including seven parts: a master control unit, a CODEC unit, a data compression code / decode unit, an asymmetrical ciphering unit, a symmetrical ciphering unit, a power supply unit and an interface unit. Said device utilizes the current GSM or CDMA network to carry out identity certification and session cryptographic key transfered by the improved PK1 asymmetric ciphered code system without CA and ciphers the data by session cryptographic key to be transmitted by the circuit exchange data service supported by network and carries out inverse process at the receive end to realize end-to end cipher communication function.

Description

technical field

[0001] The present invention relates to a device and method for realizing secure data transmission of mobile communication equipment, in particular to a wireless mobile communication handheld device attached to the existing GSM (Global System for Mobile Communications) network or CDMA (Code Division Multiple Access) network, thereby performing Device for secure data communication. Background technique

[0002] With the development of mobile communication technology, people increasingly rely on and use existing wireless mobile communication equipment, such as mobile phones. The application of mobile phones has indeed brought great flexibility to the communication between people, and it can save time and is very convenient to use. However, with the wide application and increase of functions of mobile phones, such as the transmission of text and picture information, and even some mobile phones can also realize the function of fax, the problem of information sec...
