Date of Defense 1998-09-17 Availability restricted Abstract In the coming millennium, the establishment of virtual enterprises will become increasinglycommon. In the engineering sector, global competition will require corporations to create
agile partnerships to use each other’s engineering resources in mutually profitable ways.
The Internet offers a medium for accessing such resources in a globally networked environment.
However, remote access of resources require a secure and mutually trustable environment, which
is lacking in the basic infrastructure on which the Internet is based. Fortunately, efforts
are under way to provide the required security services on the Internet. This thesis presents
a model for making distributed engineering software tools accessible via the Internet. The
model consists of an extensible client-server system interfaced with the engineering software
tool on the server-side. The system features robust security support based on public-key and
symmetric cryptography. The system has been demonstrated by providing Web-based access to a
.STL file repair program through a Java-enabled Web browser.
