K-State Computer Scientists Developing Techniques to Strengthen the Security of Information Systems for Health Care, Military Data

by sparky3887

Kansas State University (KSU) researchers, in collaboration with Princeton University (PU) computer scientists, are developing tools to secure information systems spanning large distances. The research team, led by KSU’s John Hatcliff and PU’s Andrew Appel, received a five-year, $3 million grant from the Air Force Office of Scientific Research. The new tools involve creating mathematical and logical models that can be used by special auditing programs to make sure that information systems are secure. “We’re doing foundational research on novel forms of mathematical models and logics that enable designers and analysts to precisely state what information is allowed to flow from one point to another and under what conditions,” Hatcliff says. The researchers also are working with Rockwell Collins, a company that creates communications and aviation electronics. Rockwell Collins wants to apply the KSU research to several systems currently in development at the U.S. Department of Defense. The new tools also have the potential to be integrated into the health care system for use with patients’ medical records, Hatcliff says. The researchers say the tools already have been used by several academic research groups and various industries from around the world.

Service-Oriented Ecosystem Enables Low Cost Devices to Form Interactive ‘Web of Objects’

by sparky3887

A service-oriented environment for high-level communications between computer systems and smart embedded software components that enables even low-cost devices to cohere into a “web of objects” has been created by the EUREKA ITEA software Cluster SODA project. The technology emphasizes simplicity and ease of implementation as all devices in the web of objects communicate using the Web Services language. “With Web Services, you can directly connect your device to the ERP server without any intermediaries or protocol conversions or data manipulation,” says SODA project leader Francois Jammes. The earlier ITEA SIRENA project was the site of the development of the original proof of concept for embedding Web services in inexpensive devices. SODA devised the general environment to manage applications founded on service-oriented architecture, and the ITEA project established demonstrations of full application life cycles in a number of domains, such as industrial automation, telecommunications network and terminal management, and home automation encompassing both linkage of disparate domestic systems and elderly care. The results of the demonstrations are being incorporated into real-world applications. The Organization for the Advancement of Structured Information Standards globally adopted the service-oriented ecosystem concept as the Devices Profile for Web Services (DPWS) standard in June 2009. Although the intent of DPWS bears a similarity to the universal plug-and-play standard, DPWS facilitates dynamic discovery and is fully calibrated with Web Services technology, permitting seamless integration of device-provided services in enterprise-wide applications.

$250 Million Initiative for Science, Math Teachers Planned

by sparky3887

U.S. President Obama has announced a $250 million effort to improve science and mathematics instruction in order to help the United States compete with economic rivals. The initiative will prepare more than 10,000 new math and science school teachers and provide on-the-job training for an additional 100,000 teachers over the next five years. The plan adds to a campaign for science, technology, engineering, and mathematics (STEM) education, increasing funding to more than $500 million. In 2007, international math testing found that U.S. fourth graders trailed students in parts of Europe and Asia, and eighth graders were behind a few key Asian powers. Similar results were found in the sciences when comparing U.S. students with their international counterparts. In response to the studies, Obama created the $4 billion Race to the Top U.S. grant competition for education reform funding. The private sector also is getting involved in STEM education. For example, Intel will offer an 80-hour math course to help elementary school teachers develop expertise in math and science. “There’s a lot of research that says if the teacher has that content knowledge, they can spark excitement,” says Intel’s Shelly Esque. Meanwhile, the Woodrow Wilson Nationals Fellowship Foundation will expand a program that places math and science teachers in hard-to-staff school districts in areas of Indiana, Michigan, and Ohio. The program seeks to train 700 new teachers over the next three years. Obama’s plan also includes a $13.5 million expansion of the UTeach program, through which universities plan to deliver 7,000 expert teachers by 2018.
