We offer new Voice and Data Encryption Module AT Crypt One for highly secure voice and data communication over analog narrow-band radio channels. Complex digital signal processing techniques in conjunction with state-of-the-art encryption techniques ensures excellent speaker recognition with highest security.
The AT CRYPT ONE is a high security voice encryption system which is mainly used for authorities, governmental agencies, police and military or paramilitary. AES encryption algorithm providing the highest security needed for such user groups. From a practical standpoint, it is not susceptible to attack by eaves-droppers, etc. or by using current crypto analytical methods. Customised encryption algorithms or number generators can be integrated if required.
The AT Crypt One Voice Encryption System can be implemented into already existing radio networks for end-to-end encryption without the necessity of changing radio communication infrastructures. The AT Crypt One system guarantees a secure and economic solution for high security applications without compromise.
The AT Crypt One is compatible with complex radio networks, such as multiple repeaters and simulcast systems. No wider bandwidth is needed for encrypted mode. For relay operation, no special repeater is required.
User defined encryption algorithms and addressing schemes can be integrated. Different waveforms according to STANAG or MIL can be downloaded for interoperability. The user can select standard waveform and protocol, custom defined or standarised procedures by local settings to ensure interoperability between different user groups. This flexibility is given by using modern FPGA technologies. The AT Crypt One can be used for V/UHF as well as for HF SSB radio channels. Channel typical behaviours like fading and Doppler effects are compensated automatically. MACH2 versions for airborne platforms are available.
The high security encryption technique applied for the AT Crypt One is not affected by any political considerations. This leads to a very high level of security, an absolute must for military theatre deployment, for special police task force units or other governmental security organs.
