Description
Technical field
The utility model belongs to the secure communication unit field, especially a kind of secret mobile phone with identity recognition function.
Background technology
In the gsm wireless network, information transmitted is along with aloft freely propagate by radio wave in communication process for radio transmission apparatus, as long as use corresponding receiving equipment, who can arbitrarily receive these signals.And voice signal directly transmits in the base band mode, does not use any cryptographic algorithm, and what transmit on the talk channel is that expressly the third party of malice is easy to just can recover the voice in the circuit, can't tackle the monitoring of equipment such as " mobile phone tapping devices " at all.For preventing that the radio transmission apparatus aerial signal from divulging a secret, three kinds of secret precautionary measures are arranged traditionally: frequency hopping, perturbation technique and encryption technology at present.Though above-mentioned three kinds of technology can significantly reduce the possibility that information is divulged a secret in transmission course, still can not give effective protection for the confidential information of mobile phone storage inside, for example mobile phone is lost, and the personnel that obtain mobile phone just can obtain confidential information in the mobile phone.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of secret mobile phone with identity recognition function is provided, and this mobile phone can effectively be differentiated using the client to carry out identity, the speech quality height, and good confidentiality, the cost cost is low.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of secret mobile phone with identity recognition function, comprise display module, Keysheet module, power module, sound source module, modulator-demodulator, antenna, memory, encryption and decryption module and primary processor, display module, Keysheet module, power module, sound source module, modulator-demodulator, memory and encryption and decryption module are connected with primary processor respectively, antenna is connected with modulator-demodulator, and wherein the port of this primary processor is connected by data wire is two-way with an IC-card module port.
And IC-card module and IC-card are used, built-in RSA1024 algorithm of IC-card and SHA1 algorithm.
And the model of described primary processor is C8051f120.
And the model of described encryption and decryption module is SSX20.
And described sound source module is made of PCM codec and AMBE vocoder, and the PCM codec is connected by data wire is two-way with the AMBE vocoder, and the PCM codec connects microphone and receiver, and the AMBE vocoder connects primary processor.
And the model of described PCM codec is MC145481.
And the model of described AMBE vocoder is DVSIAMBE2000.
Advantage of the present utility model and beneficial effect are:
1. the display module, Keysheet module, power module, sound source module, modulator-demodulator, memory and the encryption and decryption module that originally have the secret mobile phone of identity recognition function are connected with primary processor respectively; antenna is connected with modulator-demodulator; wherein the port of this primary processor is connected by data wire is two-way with an IC-card module port; can differentiate the use client identity authentication; prevent that effectively the malice third party from using this secret mobile phone, protection cell-phone internal information safety.
2. the secret mobile phone sound source module that originally has identity recognition function is made of PCM codec and AMBE vocoder, the PCM codec is connected by data wire is two-way with the AMBE vocoder, the PCM codec connects microphone and receiver, the AMBE vocoder connects primary processor, the setting of this kind structure can realize the simulation and the digital translation of voice, digitize voice is carried out compressed encoding and process of decoding, when reducing the speech data flow, keep call tone quality preferably.
3. of the present utility model simple in structure, design science is reasonable, can effectively differentiate using the client to carry out identity, and the speech quality height, good confidentiality, the cost cost is low, is the higher secret mobile phone with identity recognition function of a kind of fail safe.
