Encryption Devices Now Available for Globalstar Phones

Easy-to-use Technology Developed By CopyTele for Extra Voice and Data Security

SAN JOSE, Calif.–(BUSINESS WIRE)–May 17, 2001–Globalstar (NASDAQ:GSTRF), the global mobile satellite telecommunications service, and CopyTele, Inc., (NASDAQ/NMS:COPY), a developer and provider of multi-functional encryption products, today jointly announced the introduction of the CopyTele DCS-1200, an encryption device that attaches to Globalstar phones to provide end-to-end security for satellite voice and data calls.

The DCS-1200 is the first security device to be made commercially available for use over the Globalstar system, providing strong levels of encryption on top of the high degree of security that is already inherent in Globalstar’s CDMA architecture.

Using the DCS-1200, voice signals are digitized at a rate sufficient to produce very high quality voice and then encrypted with one of several algorithms. They are then sent over the Globalstar satellites as circuit switched asynchronous data and decoded by a receiving DCS-1200 unit which converts the data back to an audio signal.

The default encryption algorithm used by the device is the CITADEL(TM) CCX by Harris Corporation. It features a 128 bit encryption key, which provides more than 3.4 x 1038 possible coding combinations. The DCS-1200 also supports data encryption at either 4.8 or 9.6 kbps. The DCS-1200 can alternatively be programmed with Advanced Encryption Standard (AES) or Data Encryption Standard (DES) digital cryptographic algorithms. All of these ensure users the highest degree of commercially available protection against unauthorized signal interception.

The DCS-1200 can also be used with many terrestrial cellular systems which support circuit switched asynchronous data and with analog office telephones. This means that calls from Globalstar phone to Globalstar phone, Globalstar to cellular, Globalstar to wired phones, cellular to cellular and wired to wired can be encrypted. The device also supports encryption of files within computers and software to protect against viruses.

The DCS-1200, which supports both RJ8 and DB9 (RS-232) interfaces, runs either on AC power or using an internal rechargeable battery that is sufficient for more than four hours of operation.
