Description

Remote delete method of security information in handheld type radio set}

The present invention relates to a method for remotely erasing security information of a small radio, and more particularly, to a method for remotely erasing security information for maintaining security in a small radio operated in an ad hoc manner.

Conventional small radios can perform only voice-oriented communication functions with analog radios, and have a built-in security function for voices. However, in the case of a radio takeover or loss, all contents communicated through a lost radio are intercepted. There is a vulnerability that can be exploited.

Small radios that do not have an ad-hoc function did not have to consider the security of the radios in charge of the relay.

However, small radios are usually used in squad-level units in combat units in the military and are therefore likely to operate in close combat with opponents, thus requiring security for traffic.

In the past, the security of the communication was given as a 'security button', a fixed security algorithm was used, and the equipment was being operated without any consideration of a takeover or loss situation.

In case of loss or exploitation, it may be necessary to change the entire military security system.

In the case of portable equipment such as radios, the risk of loss or deodorization is higher than that of other equipment.

Radios with small ad-hoc functionality must be secured due to the nature of the radio when used in groups of units.

If it is necessary to maintain security, the radio that handles the relay in the middle with the Ad-hoc function will process the voice if the voice is processed by the codec (codec), or bypass it without bypassing the codec (codec). The interface includes an interface that allows to determine whether or not to hear the voice.

This interface is used by the Organizer initially set as an operation environment setting or by selecting a security mode at the time of origination.

Through this, it is possible to perform communication (communication) by performing voice security as needed in the radio operated by 1: N communication concept.

If a small radio having such an ad hoc function is lost or stolen, security measures are required when exposing security.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

In the present invention, the radio is a small hand-held radio capable of voice and data communication, and when operating the radio as well as 1: 1 communication as well as 1: N communication is possible.

The radio in the present invention has an ad hoc (Ad-hoc) function, it is possible to operate over the limit of the basic communication distance of the radio through the ad hoc function.

An object of the present invention is to secure the security of a small radio by establishing an algorithm suitable for operating a system for providing security in voice and data communication in a small radio having an ad hoc function.

In addition, due to the characteristics of the small radio, security is not exposed even in case of loss or takeover, so that it can have continuity in traffic security of the small radio.

The small radio in the present invention performs communication with power capable of communicating over a certain distance.

In addition, through the ad-hoc function, if a radio of the same type exists between radios located at a remote location and is not in a communication state, a relay function can be used to communicate even at a remote radio period.

Even if the front radio is lost or stolen, the ad hoc function can be used to delete the security information of the security module to maintain the security system. It is an object of the present invention.

1 is a view showing the configuration of a small radio of the present invention.

The small radio of the present invention comprises a handset 110, a radio body 120, an antenna 130 and a battery 140.

The handset 110 is connected for voice communication, and data can be displayed on the display assembly 121 in the transceiver main body 120 or a PC can be connected to receive a file.

The transceiver body 120 is comprised of a baseband assembly, a wireless transmit and receive assembly, and an exhibitor assembly.

The wireless transmit / receive assembly consists of an LNA 128 and a Power AMP 127 that are responsible for RF transmission and reception.

The display assembly includes a key 122 and a display 121 for a user interface.

The baseband assembly includes a modem 123 for processing voice and data. The baseband assembly receives CPU control during transmission and reception and processes voice and data through a security key 125.

2 is a view showing a security key processing interface of the small radio of the present invention.

Before the voice data is transmitted to the output of the vocoder 210, the data is encrypted and transmitted through the security key of the FPGA 240.

Like voice, data through the CPU 220 is also encrypted through the security key of the FPGA 240 and transmitted to the other party.

Encryption is performed by reading the security key stored in the SD memory 230 and using it.

The output of the FPGA 240 is encrypted so that the voice / data can not be restored even though all processes of demodulation are identically performed with non-translated traffic.

In the case of reception, the voice / data received through the RF of the small radio is converted into non-speech voice and data through the FPGA's decryption logic and the general voice and data, and the voice is a vocoder 210. ) Is processed in the CPU 220.

Remote information erasing method of the small radio of the present invention can be applied to a small radio capable of performing communication in an ad-hoc manner, and when a radio is stolen, the radio normally stolen is planned for operation and operated. Since the ID of the stolen radio can be known.

Remote information erasing method of the small radio in the present invention, the radio is seized through the Air Interface with the built-in security module through the command of the front panel of the radio before the security module is released when the radio is seized By allowing secure module information to be deleted, the stolen radio is not required to perform any action while the power is on and is performed without the stolen person being aware of it.

In the state in which the security module is deleted by the method of remotely erasing the security information of the present invention, even if the communication channel is set to the same frequency, voice and data between radios in operation of the security module cannot be properly restored and the continuity of the security system can be maintained. .

3 is a view showing a process of operating in an ad hoc (Ad-hoc) method using a small radio in the present invention.

Voice or data output from the outgoing radio 310 is relayed through at least one of the relay radios 320 and 330.

The ad hoc function performs a relay function if a radio of the same type exists between radios located at a remote location and is not in a communication state, and communication between remote radios can be performed through this relay function. .

Incoming radio 340, in principle, can be freely receive the relayed voice and data through the relay (320, 330), but not in the communication range impossible to communicate in the outgoing radio (310).

4 is a flowchart illustrating a method for remotely erasing security information of a small radio according to the present invention.

If a radio is stolen or lost during a mission through the radio, the radio moves through the operation, so each radio ID and location can be identified at any time.

In other words, if the ID of the stolen or lost radio is found, the stolen radio must be cleared in a short time so that the radio contents and data transmissions transmitted or received during the friendly radio period are not exposed.

Enter the ID (ID) of the stolen radio to delete the security information in the radio 410 that can be ordered to erase the security information and if the erased radio is within the mastery of the security information of the stolen radio The protocol can be performed.

If the stolen radio is not within the range, the security information deletion protocol is executed through the ad hoc function through the adjacent relay radio.

In the present invention, a method for remotely erasing security information of a small radio receives an ID (ID) and an erasing command of the radio 430 from which the relay radio 420 is seized from the security information erasing command radio 410 (S410).

When the relay radio 420 receives the ID and the erase command of the stolen radio, it stores the ID of the stolen radio and floods the message " Request radio ID verification request " Flooding) (S420).

Flooding means that a relay radio delivers traffic such as a 'Radio ID verification request' message to a plurality of all adjacent radios within a mileage range.

If the relay transceiver 420 does not receive a 'radio ID confirmation' message from the neighboring radios, it will continue to transmit at regular time intervals.

When the relay transceiver 420 receives a 'radio ID confirmation' message from the radio 430 having the stolen radio ID, the relay transceiver 420 transmits a 'security module information erasure request' message (S440).

The relay radio 420 receives a 'security module information erasure confirmation' message from the radio 430 that is seized (S450), and performs authentication by exchanging keys between the security modules between the security modules (S460). Security information is erased from the radio 430.

When the security information erasing is completed, the radio transceiver 430 is notified that the security information has been deleted by transmitting a 'security module erasure confirmation response' message to the relay radio 420.

When the relay radio receives the 'Security Module Clear Confirmation Response' message, the relay radio deletes the radio's ID from the memory.

After deleting the ID of the stolen radio, the relay radio 420 transmits a 'remote erasure confirmation' message to the security information erasing command radio 410 (S480) and transmits that the security information of the stolen radio has been deleted.

Through this process, the security information of the stolen radio is remotely deleted.

In the method of remotely erasing security information of such a small radio, a plurality of radios may be included to perform the role of the relay radio 420.

In the present invention, in the case of a radio transceiver 430 that is stolen from a remote radio erasing method of a small radio in the present invention, and a radio transceiver 420-2, 420-3 that does not directly perform a protocol, the radio that is remotely deleted without knowing the situation of being remotely deleted In order to prevent this operation, the ID (ID) can be flooded, and the message " Warning Radio ID & Deletion Completed " Can be repeatedly transmitted continuously (S490).

As described above, optimal embodiments have been disclosed in the drawings and the specification. Although specific terms have been employed herein, they are used for purposes of illustration only and are not intended to limit the scope of the invention as defined in the claims or the claims. Therefore, those skilled in the art will appreciate that various modifications and equivalent embodiments are possible without departing from the scope of the present invention.
