We describe how we implemented the avatars we use to represent users in LivingSpace, our implementation of the Living Worlds standard for multi-user distributed VRML worlds. Livin...
In this paper, we develop a unified theory in analyzing optimal switch box design problems, particularly for the unsolved irregular cases, where different pin counts are allowed on...
The state of the science of information security is astonishingly rich with solutions and tools to incrementally and selectively solve the hard problems. In contrast, the state of...
This paper addresses the problem of protecting the data carried by mobile agents from the possible attacks of malicious execution hosts. Specifically, we consider protection mecha...
