Military Voice Encryption System

The DSP 9000 is a family of Military Analog Voice Encryption Systems that provide long term, tactical-level security for communications transmitted over narrowband voice channels. The DSP 9000 is available in multiple configurations, including base station, manpack, and handset configurations. An extremely flexible programmable interface and MIL-SPEC design make the DSP 9000 capable of securing virtually any HF, VHF or UHF voice radio application.

The DSP 9000 utilizes a powerful Digital Signal Processor that supplies tremendous computing power used to ensure exceptional recovered voice quality and cryptographic security. All audio input/output parameters can be menu controlled. This allows a single DSP 9000 to be quickly installed on a variety of radios without requiring any hardware modifications.

Features such as half and full duplex versions, bi-directional (dual) synchronization, automatic voice/data encryption selection and storage of a large number of traffic keys clearly separate the DSP 9000 from its competitors. Additionally, the DSP 9000 is compatible with TCC's CSD 3324SE secure telephone to enable "office-to-field" secure voice communication.

Voice (Audio) Encryption Technique

TCC's Enhanced Domain Transform encryption technique begins by using a toll quality voice digitizer operating at 62.5Kbps. The digitized audio is then pseudorandomly transformed from frequency into time and time into frequency using TCC's "Enhanced Domain Transform" technique. This transform combined with a TCC proprietary compression technique virtually eliminates any residual voice intelligibility in the ciphered speech.

The enhanced domain transform is controlled by a highly non-linear digital key stream generator. The crypto algorithm can be modified by the customer using TCC's Crypto Management System (CMS-9000). One of the 800 available encryption keys stored in the DSP 9000 is chosen, along with a randomly generated Initialization Vector (IV). These two Key Generator seed variables provide a new keystream at each synchronization.

TCC's completely automatic 'hands off' key management approach is ideal for military applications. All key management parameters can be selected and controlled by a COMSEC security officer, thereby eliminating potential operator errors or compromise. The transmitting unit selects the appropriate key by means of a real time clock at a time interval set by the security officer. Automatic downline key indexing insures that the receiving unit always selects the proper key for decryption.

Handset Model

Advanced DSP technology and the latest miniaturization techniques have allowed the high level security and voice processing of the DSP 9000 base station to be reduced in size to fit in a handset configuration.

It is no longer necessary for field soldiers to carry a separate crypto unit. The DSP 9000 HS replaces the existing radio handset, thereby adding less than one pound to the weight of the manpack radio. Prior to a mission, a security officer loads the DSP 9000 HS with 200 keys and radio interface settings using TCC's SmartModule™. Once loaded, the radio operator need only select cipher or plain mode. With the addition of the HS model, the DSP 9000 family now provides a complete, integrated security solution for air, ground and sea operations.

Quality
TCC is dedicated to quality products and services. TCC is ISO 9001 certified. ISO 9001, granted to TCC by TUV, is the most stringent standard available for total quality systems in design/development, production, installation and servicing.
