10:00 AM - ITL SEMINAR SERIES: The EAP Security Challenges
The Extensible Authentication Protocol (EAP) is widely used as an authentication framework to control the access to wireless networks, e.g. in IEEE 802.11i and IEEE 802.16e networks. However, a formal treatment of security of EAP methods is still missing. In this talk we review the EAP framework and communication model as specified in the IETF draft RFC 3748. Next we briefly discuss a few commonly used EAP methods out of the numerous existing ones, namely EAP-TLS, EAP-TTLS, and EAP-GPSK. Moving on to security we will give an overview of existing efforts that have been made to formalize security of EAP methods. For instance, RFC 3748 lists a number of security properties all EAP methods should provide. However, the list is far from being comprehensive, and we will see that a formal security model, including security goals and a trust model, is still missing. Deriving a general security model for EAP methods is difficult to achieve and we identify the special security challenges of EAP that cause these problems. We demonstrate how these special properties of EAP systems can be exploited to break standard security claims of proposed EAP methods, namely channel binding, protected ciphersuite negotiation and cryptobinding. In particular, we present a series of attacks which cause claimed security properties to fail and compromise key exchange, authentication and privacy of EAP communications. We conclude with recommendations for more secure EAP implementations. Bio: Katrin Hoeper has been a guest researcher since November 2006 with ITL. Her first research project with the Computer Security Division is security analysis on the widely used Extensible Authentication Protocol (EAP) in wireless and mobility applications. This talk will share some insights on security challenges of EAP and also make recommendations on EAP implementation.

10:30 AM - JOINT SEMINAR, SURFACE AND MICROANALYSIS SCIENCE DIVISION AND CENTER FOR NANOSCALE SCIENCE AND TECHNOLOGY SEMINAR: The Secret Life of Nanoparticles: characteristics of nanoparticles and nanostructured materials that are frequently forgotten or ignored
Although it is generally accepted that nanoparticles and nano-structured materials are mostly surfaces or interfaces, the impacts of the nature of that surface are often ignored or minimized. Surface and interface contamination is present on many nanoparticles and may be, in the words of one colleague “the dirty secret” of nanotechnology. It has been demonstrated that the nature of the environment around nanoparticles can alter the structure of the particles. The properties of individual nanoparticles or isolated nanoparticles can also be altered when they are assembled or packed into aggregate systems, even if there is no significant binding or chemical interactions. The effective media of the aggregate will have properties that differ from the individual particles. Some of these effects will be described based on our studies of iron oxide and ceria oxide nanoparticles and other work in the literature.

11:00 AM - POLYMERS DIVISION SEMINAR: Controlling the Assembly of Colloidal Building Blocks
Colloidal aggregates with controllable sizes, shapes, and structures have been fabricated by dewetting aqueous dispersions of monodispersed colloidal spheres across surfaces patterned with twodimensional arrays of templates. The capability and feasibility of this approach have been demonstrated with the organization of polymer latex or silica beads into homo-aggregates that include circular rings; polygonal and polyhedral clusters; and linear, zigzag, and spiral chains. It was also possible to generate hetero-aggregates in the configuration of HF and H2O molecules that contained colloidal spheres of different sizes, compositions, densities, functions, or a combination of these features. These uniform, well-defined aggregates of spherical colloids are ideal model systems to investigate the aerodynamic, hydrodynamic, and optical properties of colloidal particles characterized by nonspherical shapes and/or complex topologies. They can also serve as a novel class of building blocks to generate hierarchically selfassembled structures that are expected to exhibit interesting features valuable to areas ranging from condensed matter physics to photonics. In this talk, I will discuss the fundamental mechanism involved in this method, and its potential use in fabricating photonic devices

10:45 AM - NIST CENTER FOR NEUTRON RESEARCH SEMINAR: Neutron Diffraction Studies of Metal Hydride Complexes
X-ray diffraction is a highly useful tool for studying complexes in the solid state. However, neutrons can provide even more precise information in cases where X-rays are inadequate. Our research is aimed at uncovering the precise position of chemically interesting hydrogen atoms in metals and metal clusters using single crystal neutron diffraction as our primary analytical tool. In this presentation, we will discuss the advantages of neutron diffraction and present, among others, the structures of OsH3Cl(PPh3)3 (a compound demonstrating a “stretched” dihydrogen ligand) and [(C5Me4SiMe3)Y(H)2]4(THF) (the first neutron diffraction study of a 4-coordinate hydrogen atom).

5/4/07 10:30 AM - OPTICAL TECHNOLOGY DIVISION SEMINAR: Radioactivity Standards for Nuclear Medicine
Abstract The number of nuclear medicine procedures being performed in the United States continues to rise, due in part to the expanding number of applications for both diagnosing and treating diseases. The safety and effectiveness of these procedures are highly dependent on the accuracy of the radioactivity measurements made in the clinic, whether they are of the amount of contained activity in the radiopharmaceutical being injected or of the measured distribution of the radiopharmaceutical in the body. The Nuclear Medicine Standards Program in the NIST Radioactivity Group provides the standards and calibrations that help ensure the accuracy and consistency of radioactivity measurement in nearly all areas of nuclear medicine practice. This talk will present an overview of the activities of the Program, including plans for a major initiative in the development of standards for Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT), key tools in medical imaging.

5/8/07 10:00 AM - SEMICONDUCTOR ELECTRONICS DIVISION SEMINAR: Are We Heading Towards Performance-Based MEMS Standards?
Research at the micro/nano-scale poses new challenges for metrology and technological advancement. This talk begins with an overview of several of these challenges. Then an interesting metrology technique will be presented, which may be used to help with such challenges. The talk will conclude with a discussion of a few benefits and applications of this new methodology. Advancements in micro/nano-scale materials, sensors, actuators, typically depend on precise measurements of new phenomena, and accurate characterizations of performances through modeling. To verify analytical and numerical models of such phenomena, it is necessary that the performance of the models match the performance of the actual devices. To accomplish this, the model and device must share the same geometric and material parameters. These parameters should be measured for each device because parameters vary across and within fabrication runs. To address this challenge, EMM is being developed to exploit the strong coupling between micro/nano-mechanical parameters and precise micro-electronic measurands. That is, it deduces many geometric, dynamic, and material properties by electronic probing. Since EMM is performance-based, it retains a clear meaning to manufacturers and users; and it applies to a wide variety of micro/nano-devices. Preliminary results show that EMM is several orders of magnitude more precise than convention.

5/10/07 1:30 PM - PROCESS MEASUREMENTS DIVISION SEMINAR: New and Renewed Technologies for Characterizing Biopharmaceuticals
Several new analytical technologies have become available over the last few years which enable more efficient characterization of biopharmaceutical products. These new or renewed analytical tools have led to a greater understanding of the structure-function relationships between the protein product and its disease target. Considerable progress has been made in utilizing new or existing tools for characterizing the 3-dimensional structure of proteins such as EM tomography, X-ray crystallography, and computer modeling. Other biophysical characterization techniques are also re-emerging to better characterize protein particles (visible and subvisible) including laser light scattering, nephelometry, analytical ultracentrifugation, microchemistry, light microscopy, and FTIR microscopy. The ability to better characterize biopharmaceuticals earlier in development enables better product and process understanding and can help accelerate progress through the pipeline.
