Problems solved by technology

[0003] The main function of the popular wireless mobile communication devices is to realize the reception and transmission of various data, and there is no guarantee in terms of safety.
Third parties can easily intercept data by eavesdropping or stealing devices
Moreover, once the previous security products are lost, it often affects the use of the entire group of users

Embodiment Construction

[0046] against figure 1 , from the perspective of working principle, the system of the present invention can be divided into three parts.

[0047]In the first part, the use of the wireless mobile security call function requires a series of certifications. This part of the work is mainly completed by the main control unit and the asymmetric encryption unit. The main steps are as follows:

[0048] 1. You must first enter the password, and then send it to the system for verification. If you make a mistake, you can re-enter. The upper limit of password input is three times. If you fail all three times, the asymmetric encryption unit will be automatically locked and then exit;

[0049] 2. Verify part of the program code, the process is as follows: get the abstract of part of the program to get r1, read the signature result of part of the program from the asymmetric encryption unit, if the signature uses the RSA algorithm: verify the signature result with the public key of the pr...

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...
