Description
Technical field
The utility model relates to secure communication field, specifically a kind of bluetooth secure communication device.
Background technology
Along with the fast development of the communication technology, the communication apparatus such as smart mobile phone, bringing easily simultaneously, also can derive the problems such as some information security hidden danger thereupon.
In order to tackle the countermeasure that security assurance information, secret call anti-eavesdrop etc. propose on domestic market, mainly concentrate on secret telephony mobile phone or this kind of Related product of third party's fail-safe software.But for secret mobile phone, need to use a difficult problem and the situations such as restriction, Domestic Carriers network formats and foreign vendor's limitation of the technology in the face of technological layer; For third party's fail-safe software, the protection just in pure software aspect, cannot obtain the administration authority of user mobile phone software-driven layer, can not stop some Malware completely and intrude into bottom most software through back door and reach illegal objective.
Summary of the invention
The utility model solves three kinds of drawbacks that secure communication mobile phone in the market exists: the variation of one secret mobile phone pattern brings poor universality; It two is on operation platform and manyly in terminal will carries out encryption and decryption, adds the cost of equipment and terminal; It three is these terminals once lose and the encryption mechanism that is decrypted, and system can be caused to be forced to out of service.
In order to the utility model that solves the problem adopts following technical scheme: bluetooth secure communication device, comprise microphone, A/D modular converter, bluetooth module, DSP enciphering/deciphering module, Bluetooth antenna, D/A modular converter and receiver, wherein said microphone is connected with A/D modular converter, the output of A/D modular converter is connected with bluetooth module, bluetooth module and DSP enciphering/deciphering model calling, DSP enciphering/deciphering module is connected with Bluetooth antenna, bluetooth module is also connected with D/A modular converter, and the output of D/A modular converter is connected with receiver.
The utility model has the advantages that, based on bluetooth earphone, arising at the historic moment of the bluetooth secure communication device of binding signal encryption technology, the demand that call secret and safe urgently promotes can be met on the one hand, the blank with voice communication safety product on domestic market can be filled up on the one hand, that one both can coded communication, again independent of communication system; Both can meet relevant national standard, a kind of novel secure communication unit of coded communication can be become again.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model;
In figure: 1-comprises microphone; 2-A/D modular converter; 3-charge management module; 4-bluetooth module; 5-DSP enciphering/deciphering module; 6-Bluetooth antenna; 7-D/A modular converter; 8-receiver.
Embodiment
See Fig. 1, bluetooth secure communication device, comprise microphone 1, A/D modular converter 2, charge management module 3, bluetooth module 4, DSP enciphering/deciphering module 5, Bluetooth antenna 6, D/A modular converter 7 and receiver 8, wherein said microphone 1 is connected with A/D modular converter 2, the output of A/D modular converter 2 is connected with bluetooth module 4, bluetooth module 4 is connected with DSP enciphering/deciphering module 5, DSP enciphering/deciphering module 5 is connected with Bluetooth antenna 6, bluetooth module 4 is also connected with D/A modular converter 7, the output of D/A modular converter 7 is connected with receiver 8, described bluetooth module 4 is connected with charge management module 3.
Bluetooth antenna 6 communicates with the verbal system possessing blue tooth interface in the present embodiment.The verbal system possessing blue tooth interface is mobile phone, but is not limited to mobile phone.
In specific embodiment of the utility model, charge management module selects MCP73855; Bluetooth module+DSP enciphering/deciphering module selects car8670.
After being connected with mobile phone by the utility model, speech security transmission and the receiving function of telephone call can be completed; Even if can not be divulged a secret by intercepting in wireless transmissions.
After mobile phone terminal input key, realize secret telephony function: the microphones of this equipment is to voice analog signal, digital signal is converted to by the A/D modular converter in bluetooth module, digital signal is through the process of DSP enciphering/deciphering module encrypt, become scrambled digital signal, send mobile phone to by Bluetooth antenna.Coded signal is transmitted by cell phone network, the conversation signal being through encryption of transmission.Signal arrives the reception mobile phone terminal of secret telephony, by the speech scrambling signal of Bluetooth antenna received communication receiving terminal mobile phone, then common digital signal is become via the process of DSP enciphering/deciphering module decrypts, this signal becomes analog signal by the D/A modular converter of bluetooth module, outputs to bluetooth earphone receiver.What whole communication process transmitted is coded signal, serves the privacy functions of anti-eavesdrop.Above analog-to-digital conversion and digital-to-analogue conversion by building corresponding modular converter to realize, also can be selected the Bluetooth chip with translation function, realizing in Bluetooth chip.
In order to use of the present utility model, at mobile phone terminal, APP can also being installed, checking for performing key, secret telephony audit, the function such as illegal operation warning.
The utility model can be used for the secret and safe call in the fields such as public security People's Armed Police, the administration of justice and law enforcement agency, military project unit, financial industry, scientific research secret unit, civil servant, public institution.
