Poland Cryptographic Telephone

Specifications: Cygnus Silver is first common use cryptographic telephone that has been developed and made in Poland. It is destined for width range of customers where option of call security is necessary. Our analog cryptographic telephone can work with public telephone network or internal network and on a/b ports with ISDN network as well.

Cryptographic algorithms that are used for calls security belongs to some modern solution on over the world. They assure safe connections with confidential clause level. Cygnus Silver cryptographic phone works not only In cryptographic mode, but it enables connection with any other telephone too.

Cygnus Siver consists with following designs that are placed in one housing : - analog standard telephone set - cryptographic telephone set - cryptographic modem Hereby presented phone has the modern, sophisticated housing, big display and multilanguage menu. It fulfils Polish Standard requirements for analog telephones.

Main features of - open or cryptographic communication mode of work - telephone book with 1000 numbers of capacity - direct 10 memories - last number memory - flash - automatic redial - calibrated pause - operator\'\'s number dialling - loudspeaker mode - MUTE - programmed menu - most functions of phone are programmed from user level - telephone\'\'s settings are protected by access code . - power fail supplying Cryptographic communication mode of work: - it is performed by AES symmetric cryptographic algorithm with session key 192 bits of length. - automatic generation of session keys. - change of session key by means of Diffe-Hellman diagram with 1024 bits of length. - security against masquerade. - possibility of transfer from open mode to cryptographic mode of work by means of one key pressing.

Time of transfer about 2 sec. - acoustic and visual information of transfer to cryptographic mode of work.

Modem parameters: - full V.34 standard is performed at cryptographic mode of work - connection to PC by means of RS232 series interface (to 115 200 bits/sec.) - Cygnus Silver is some best solution of telephone communication confidence for private and business applications.
