Heterogeneous workstation to STU-III prototype
E.M. Kayden, L.J. Schaefer · 2002
Secure communications between heterogeneous workstations via the public telephone utility is necessary in the Department of Defense (DOD) and in the civil agency environments. A prototype was developed using two heterogeneous workstations attached to Secure Telephone Unit-IIIs (STU-IIIs). Custom software was developed to provide an interface between the trusted operating system and the STU-III. This custom software controlled the STU-III connections to the operating system. This paper describes the components of the prototype, the operation of the custom STU-III software, and the findings based on this effort.>
