Security is of critical importance for e-business systems, in which multiple internal and external enterprise applications and data are linked into one integrated system. It is a key factor that will determine how comfortable successful companies and their associated constituents are going to be with the idea of integrated e-business systems and the virtual enterprise. Existing proprietary access ...

As the deployment of mobile devices becomes ubiquitous and special interest groups and governments create laws to require the tracking of mobile users, user privacy is under serious threat. Being able to identify and locate an individual also creates a potential liability for service providers. Today the only private wireless communication system is the pre-paid cell phone. However, a pre-paid sys ...

Current state-of-the-art technology for specifying and enforcing security policies for software is generally too inflexible, coarse-grained, and difficult to use. In systems that make use of mobile code, such as Java applets, the situation is yet more difficult. A more flexible and powerful approach is needed that will allow a wider range of security policies to be set by various policy-setting au ...

IEM is an established sensors and instrumentation company with transportation measurement systems in 15 countries. Visibility is one of the most critical pieces of environmental information in promoting safe traffic operation and traffic management in all modes of transportation: ground, maritime, and air. Typical visibility sensors determine the scattering properties within a relatively small air ...

Researchers at the NIST have demonstrated a programmable Voltage Standard (VS) chip based on SNS (superconductor-normal-superconductor) tunnel junction technology. Excellent programmable voltage standards were demonstrated using this SNS technology in a liquid helium-based system. At HYPRES, we have developed and commercialized a Closed Cycle Refrigerator (CCR)-based DC voltage standard system usi ...
