"Garant-1 / E1"

"Garant-1 / E1" is a cryptographic protection device for standard digital channels "E1".

The device "GARANT-1 / E1" is designed to provide cryptographic protection with guaranteed stability of two standard counter digital channels "E1". It can be used for the formation of corporate networks of confidential telephony based on leased public digital network channels.

Operating of the device is designed for difficult climatic and mechanical conditions.

The radio interference station "Manushak-T" is designed to detect, localize and influence high-frequency stationary radio networks and radio channels in the ultrashort range (30-500 MHz) of tactical control of the enemy troops.

The station provides collection and registration of radio intelligence data, examination and processing of enemy troops at a distance of up to 50 km from the frontal side and from depth up to 20 km of the location, identification of radio signal sources, communication load, and evaluation of the results of impact on interrupted channels. The station provides hardware and software means for organizing data exchange with a higher-level automated command post.

Information protection

  • ''GARANT-1 / E1'' provides a guaranteed level of security for the protected information.
  • The product uses a certified cryptographic information encryption algorithm, adapted to the specificity of combined data communication  transmission and voice information in real time.
  • Symmetric keys with a length of 256 bits are used.
  • Keys can be loaded directly into the encryptor, as well as they can be formed according to the principle of an open-source distribution of Diffie-Hellman keys, using the parameters loaded along with the keys.
  • Formation of a session key with periodicity of 1 min.
  • The product provides the ability to make changes in the parameters of a secret key formation directly from the user with the help of special device for key loading (UZK-1).
