Sirrix.Radiocrypt

Over the air radio communication is easily interceptable and today, almost anyone can eavesdrop radio communication with simple, publicly available tools. Especially military and other governmental organizations depend in their work on confidential and authentic communications. Insufficient security for information over the air can cause severe damage to safety, threaten lives and affect economy.

Therefore, it is essential to protect sensitive information from unauthorized access or any manipulation.

Solution

Sirrix.RadioCrypt modules are designed to provide the highest level of security of radio communication against eavesdropping. Sirrix VHF/UHF radio encryption modules are a perfect cost effective solution for high-end voice encryption for governmental and defence organizations, police departments and public safety organizations.

Sirrix offers wire-in modules for easy installation into most common and well known mobile radios including Motorola, Kenwood and others. The Sirrix.RadioCrypt modules use a highly sophisticated, DSP-based Vocoder to compress the speech and thus, adapt the audio signals to the low-bit channel rate. That ensures a high audio quality, despite of the narrowband FM channel.

The audio signals are encrypted and transmitted using a special multicarrier modem technology for an optimal bandwidth usage of the radio channel and preserving the full radio range.

Features

The Sirrix.RadioCrypt modules integrate strong digital, AES-based, end-to-end encryption on legacy analog radio systems.The modules support multiple user groups with different keys. The late entry function allows new group members to join already established an deployed groups within less than one second. The modules come along in a tiny format, and adapted for each radio type.

They can be integrated in radios like Kenwood TK 3140 and TK 8180 or Motorola GP 380. Other handheld or mobile radios are available upon request. If necessary the module can be repackaged to meet mechanical and electrical requirements. An external, plug-in solution can also be provided on request and radio type. The high grade cipher algorithm AES with a key length of up to 256 bit provides a state-of-the art secure transmission.

The Sirrix.Radio-Crypt module provides a high-grade digital voice cipher system, especially designed as an integrated module for VHF/UHF based FM radios, using robust multicarrier modem technology. The Sirrix.RadioCrypt module enables optimal connections even under poor radio conditions. Even with very low transmission speeds Sirrix.RadioCrypt modules deliver an excellent audio quality and speaker recognition in real-time. Due to the narrowband voice coding and multicarrier modem, there is no reduction in radio range compared to normal clear voice operation of the radio.
