Tektronix Inc, Wilsonville, Oregon, and trusted Unix house, Addamax Inc, have inked a co-development pact to produce a line of secure X-terminals. Addamax is implementing ATX, its secure X Window subsystem, on the TekXpress family of X-terminals to create a line for B1 and networked Compartmented Mode Workstation environments. Addamax said it will integrate a trusted TCP/IP networking product, ATN, to the terminals assuring Compartmented Mode compliance, compatibility and interoperability with other trusted systems including Digital Equipment Corp and Sun Microsystems Inc’s Compartmented Mode Workstations. ATX, the foundation of the secure X-terminals, is based on the Addamax Workstation, currently under evaluation by the US National Computer Security Center and the Defense Intelligence Agency for B1 and Compartmented Mode Workstation ratings. It is based on Unix System V.4 and supports both the Open Look and Motif graphical user interfaces. The two companies intend co-marketing their work through their respective distribution channels, with Addamax providing the software support and maintenance. The only other secure X Window Systems terminals come from Network Computing Devices Inc, which is using the Addamax software, and Human Designed Systems Inc, whose security comes from Addamax competitor SecureWare Inc. The Human Designed-SecureWare offering is only accredited as a single-user Compartmented Mode Workstation.
