Abstract
The utility model discloses a device for realizing the secure communication safety of a mobile secure terminal, which is composed of a shell of the device and a circuit, wherein the shell of the device is provided with a status indicator and a power switch; the circuit is arranged in the shell of the device and realizes wireless connection with a secure terminal, carries out terminal identity authentication and sends split secret keys and algorithm programs to the secure terminal; the circuit is composed of a Bluetooth interface module circuit, a control module circuit and a power supply module circuit, wherein the Bluetooth interface module circuit is connected with the control module circuit; the Bluetooth interface module circuit and the control module circuit are respectively connected with the power supply module. The utility model has the advantages that because the secret keys and the algorithm programs are split and stored in the utility model and the mobile secure terminal, the utility model and the mobile secure terminal can be used in an authentication mode only when the utility model and the mobile secure terminal are bound, and after the distance between the utility model and the mobile secure terminal is larger than 10 meters, the split secret keys and the algorithm programs stored in the mobile secure terminal are automatically destroyed, so that harm can not be caused if the mobile secure terminal is lost. The utility model has the advantages of simple structure, small size and convenient operation.
Description
Technical field
The utility model relates to a kind of device that can guarantee to move secret terminal security communication security, particularly relates to the protective device that a kind of and mobile secret terminal realizes wireless connections, guarantees its secure communication safety.
Background technology
Move secret terminal (moving secret terminal, vehicle-mounted secret terminal etc. as GSM) when the secure communication service is provided for the user, himself also exists various potential threats, moves secret terminal as illegally using by force; Personation validated user steal moves secret terminal; Steal or distort cryptographic algorithm and the cipher key store that moves on the secret terminal; Lose separate unit and move secret terminal or intellective IC card etc.Therefore, must take safety precautions to moving secret terminal, to reduce potential threat to its generation.Such as, to private datas such as the key that moves secret terminal storage, cryptographic algorithm, adopt the encryption of cryptographic algorithm to cover protection, and it is stored in respectively in the FLASH memory, intellective IC card of CPU; Intellective IC card is provided with PIN (password) protection, when making it the PIN input error, can not reads the technical measures such as private data of intellective IC card.
Yet existing to move the safety measure that secret terminal adopted perfect not enough, still exists owing to move losing of intelligent IC that secret terminal and binding use, and cause the serious threat to the user cipher device communication security.
Summary of the invention
The objective of the invention is to: for using the user who moves secret terminal, provide a kind of and the supporting use of this terminal, can guarantee the protective device of this terminal security communication security.
Goal of the invention of the present utility model realizes by implementing following technical proposals:
Realize moving the device of secret terminal security communication security, by the crust of the device that is provided with status indicator lamp and mains switch, the key that is contained in the device case and realizes wireless connections with secret terminal, carries out the terminal identity authentication and cut apart to its transmission and the circuit of algorithm routine are formed, it is characterized in that: realize authentication with secret terminal and send the key cut apart and the circuit of algorithm routine, form by blue tooth interface modular circuit, control module circuit and power module circuitry; Wherein, the blue tooth interface modular circuit is connected with the control module circuit, and the blue tooth interface modular circuit is connected with power module circuitry respectively with the control module circuit.
Advantage of the present utility model is: because key and algorithm routine, be to cut apart to leave in secret terminal and this device, and in this device, write corresponding mobile secret terminal use's identification code, both only just can authenticate use mutually under the binding situation, and both are after exceeding 10 meters distances, owing to leave the key cut apart in the secret terminal and algorithm routine in by auto-destruct,, also can not work the mischief to whole system even therefore move secret lost terminal; Another advantage of the utility model is that this apparatus structure is simple, and volume is little, and is easy to use, easy to utilize.
Description of drawings
Fig. 1 is the utility model structural representation and and bluetooth GSM secret mobile phone traffic diagram
Fig. 2 is the bluetooth module circuit structure diagram
Fig. 3 is the control module circuit structure diagram
Fig. 4 is the power module circuitry structure chart.
Mark among the figure: 1, be bluetooth channel, 2 is the utility model device, and 3 is bluetooth GSM secret mobile phone.
Embodiment:
Realize moving the device 2 of secret terminal security communication security, by the crust of the device that is provided with status indicator lamp and mains switch, be contained in the device case, realize wireless connections, carry out the terminal identity authentication and the key cut apart to its transmission and the circuit of algorithm routine are formed by bluetooth channel 1 with bluetooth GSM secret mobile phone 3; Wherein: realize authentication and send the circuit of Split Key and algorithm routine to it with bluetooth GSM secret mobile phone 3, form by blue tooth interface modular circuit, control module circuit and power module circuitry, the blue tooth interface modular circuit is connected with the control module circuit, and the blue tooth interface modular circuit is connected with power module circuitry respectively with the control module circuit.
This installs 2 used blue tooth interface modules, can select the BC219159A-BN of CSR company production and sales for use, power module can be selected the MAX1792 of Maxim company production and sales for use, and control module is made up of CPU and peripheral circuit, the single-chip microcomputer C8051F020 that CPU can select for use Cygnal company to produce.
Every GSM secret mobile phone all has this device of a pairing.This device of numbering is done writing of Split Key and partitioning algorithm program in safe and secret administrative center (SCMC).Writing content comprises: the GSM secret mobile phone authenticate key of respective user, master key, working key; The IMEI number, SIM card number that are used for the corresponding mobile phone of authentication.Finish this device after data write, just can give the user use with corresponding mobile phone is supporting.
The utility model operation principle is as follows:
Make GSM secret mobile phone 3 be in open state, closely (less than 10 meters) press the mains switch on this device 2, this device is activated, its status indicator lamp glows, bluetooth module circuit in the device 2 receives the signal that GSM secret mobile phone 3 sends from its antenna, and it is transferred to the control module circuit, finish authentication by the CPU in this circuit to GSM secret mobile phone 3, Split Key and algorithm routine with storage returns to the bluetooth module circuit again, send to GSM secret mobile phone 3 by its antenna by bluetooth channel 1, finish the synthetic of Split Key and algorithm routine, make GSM secret mobile phone 3 enter the secure communication operating state, the status indicator lamp on the device sends green glow.If authentication is unsuccessful, then this device 2 can not send Split Key and algorithm routines to GSM secret mobile phone 3, and GSM secret mobile phone 3 can not be finished the synthetic of Split Key and algorithm routine, so communication channel can not connect, and the status indicator lamp that installs on 2 glows.Surpass 10 meters if GSM secret mobile phone 3 leaves the distance of this device 2, then Split Key in the mobile phone 3 and algorithm routine are by auto-destruct.
