Devices of confidential communication

DCC-001, DCC-001-01

dcc001, dcc001-01 | Special cellular phone TASKO-S

destined for cryptographic secure of confidential information, handed over through the telephone cell canals of GSM standard.
The peculiarity of the worked up cryptographic terminals is a possibility of transition from open routine option of communication, which is being conducted in straight vocal canal, to the secured one, being done with data transmission option without interruption of communication session.
A codifying Algorithm of all DCC is realized in accordance with the State Standard -28147-89 in the option of gamming with synchronized transmission and provides a block’s codifying with a key by dimension of 256 bits.
The cryptographic endurance of a secured communication canal is confirmed by state examination.
The device is certified in Ukraine.

It is possible to use symmetric and asymmetric regimen of establishing the session of cryptographic secured communication.
In first option the key information in DCС is renewed up once in a month, and keys attached to authority of confidential communications are interchanged automatically once in a day. In second option renovation of key information is being done not often then once in a year, and the keys in DCС are being issued for every session of telephone communication on the base Diffy-Helman`s algorithm .
Generation and inserting of key information is being performed by complex of system’s maintenance СSM-001, which may be located in centralized service center or with the concrete consumer, that ensures to him full independence of key information and high degree of securing the communication’s canals. A possibility to prevent their unsanctioned use is foreseen in the devices in the case of it’s being lost or theft.

DCC-001: The constructive variety of DCС-001 is a prefix to mobile telephone Ericsson R520I, jointed with it by the means of a standard 11-contact and making the constructive total unit with mobile telephone.

dcc-001-1: The constructive variety of DCC-001 is made on the base of mobile telephone Sony Ericsson T310 by inserting inside the telephone the cryptographic secured plate.
