Bridge Communications Inc – now a subsidiary of 3Com Corp – and AT&T have a novel application of AT&T digital encryption technology that will offer new levels of security for communications within local area networks. By using AT&T’s T7000A Digital Encryption Processor, Bridge’s Government Products Division has brought to market what it claims are the first local network products with data encryption capability along with industry-standard high-level network protocols. The T7000A digital encryption device enables data security by encrypting, or scrambling in a code, data before it is transmitted through the modem, then decoding the encrypted data at the receiving modem. Bridge’s Secure CS/50 Communications Server and Secure NCS/AT Network Control Station are the first two members of a family of products providing data security and access control in sensitive or controlled environments. They are based on the US Department of Defense’s TCP/IP Transmission Control Protocol/Internet Protocol. The new products employ AT&T’s T7000A Complementary Metal Oxide Semiconductor device, introduced in 1985. Bridge says that the unique application not only offers cutting-edge security for proprietary transmissions, but also widens the scope of network users for the AT&T technology, claimed to be the fastest, lowest-power point-to-point encryption device on the market today.
