Military Ciphering System
The DSP 9000 is a family of Military Ciphering Systems that provide long term, strategic security for communications transmitted over narrowband channels. The DSP 9000 is available in base station, manpack, and handset configurations. A programmable interface and MIL-SPEC design make the DSP 9000 capable of securing virtually any HF, VHF or UHF application.
The DSP 9000 utilizes leading edge technology throughout its design. A powerful Digital Signal Processor supplies tremendous computing power that is used to ensure exceptional recovered voice quality and cryptographic security. All audio input/output parameters are software controlled. This allows a single DSP 9000 to be quickly installed on a variety of radios without modifying the hardware.
Exclusive features such as half and full duplex versions, dual synchronization, automatic voice/data encryption selection and storage of a large number of keys also 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" communication.

Key Management and Cipher Technique
TCC's Enhanced Domain Transform encryption technique begins by using a toll quality voice digitizer operating at 64 Kbps. 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 eliminates virtually any residual intelligibility.
The domain transform is controlled by a highly non-linear digital key generator. This crypto algorithm can be modified by the customer using TCC's Crypto Management System. One of the selected encryption keys stored in the DSP 9000 and a randomly generated Initialization Vector (IV) provide a new keystream for 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 SmartModuleTM. 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.
