3Com’s Bridge Communications Corp, and AT&T, claim to have come up with a product family that will offer new levels of security for local area network communications. Based on AT&T’s T7000A CMOS digital encryption processor, the Secure CS/50 Communications Server and Secure NCS/AT Network Control Station designed by Bridge’s government products division are the first two members of a family of products designed to provide data security and access control in sensitive or controlled environments using standard high-level network protocols. The server and net-work control station use the TCP/IP protocol.
