On July 10, 2012, the National Institute of Standards and Technology (NIST) published its first-ever draft guidelines* to help utility companies test their procedures for upgrading meters securely from a remote location.
The draft publication offers a generic set of testing criteria to help any utility determine whether its method of upgrading meters conforms with the security and functionality requirements in the National Electrical Manufacturers Association (NEMA) Standard for Smart Grid Upgradeability. NIST and the Smart Grid Interoperability Panel identified the need for meter upgradeability requirements as a high priority calling for immediate attention, and NEMA led the effort to develop a standard set of these requirements on a rapid schedule.
Smart meters, like other components of "smart power grids," will permit two-way exchange of data with other grid-connected devices, relaying information such as power prices, outage alerts and grid errors. Power companies likely will have different means of making sure the firmware—operating software stored on updatable memory chips—remain up to date, so the draft guidelines offer a test framework that includes test procedures, detailed steps for conducting the test, reviewing results, and producing records to assess and report on these results.
"Companies will be able to tailor these generic test criteria to their own systems," says Marianne Swanson, senior sdvisor for Information Security at NIST. "To make it an effective framework, we made sure that it contains consistent, repeatable tests they can run, producing documentation that contains adequate, accurate information regardless of the individual system."
Swanson emphasizes that the use of the testing framework is strictly voluntary, and says that NIST will work to enhance this framework as comments on the draft come back.
"We will be working with the Department of Energy, including Oak Ridge National Laboratory (ORNL), and also Electrosoft Services Inc., to utilize an existing upgrade management system that ORNL developed, and that now NIST can test," she says. "We will be using the comments as well as lessons learned during the test implementation to update the guidelines. We will also be sharing all this information with ANSI, which would like to use the NEMA standard and these guidelines as seed documents for a for a future NEMA-published ANSI standard."
Swanson adds that while the official comment period for the guidelines will run only for 30 days, the team anticipates that the development of the testing framework will continue up until publication of the document's final version in April 2013. Interested parties can contact NIST in the interim with further recommendations.Copies of Advanced Metering Infrastructure Smart Meter Upgradeability Test Framework (NISTIR 7823), are available at http://csrc.nist.gov/publications/drafts/nistir-7823/draft_nistir-7823.pdf. Comments on the draft are due Aug. 9, 2012, and should be emailed with "NISTIR 7823" in the subject line to firstname.lastname@example.org.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
