    SGXIO: Generic Trusted I/O Path for Intel SGX

    Full text link
    Application security traditionally strongly relies upon security of the underlying operating system. However, operating systems often fall victim to software attacks, compromising security of applications as well. To overcome this dependency, Intel introduced SGX, which allows to protect application code against a subverted or malicious OS by running it in a hardware-protected enclave. However, SGX lacks support for generic trusted I/O paths to protect user input and output between enclaves and I/O devices. This work presents SGXIO, a generic trusted path architecture for SGX, allowing user applications to run securely on top of an untrusted OS, while at the same time supporting trusted paths to generic I/O devices. To achieve this, SGXIO combines the benefits of SGX's easy programming model with traditional hypervisor-based trusted path architectures. Moreover, SGXIO can tweak insecure debug enclaves to behave like secure production enclaves. SGXIO surpasses traditional use cases in cloud computing and makes SGX technology usable for protecting user-centric, local applications against kernel-level keyloggers and likewise. It is compatible to unmodified operating systems and works on a modern commodity notebook out of the box. Hence, SGXIO is particularly promising for the broad x86 community to which SGX is readily available.Comment: To appear in CODASPY'1

    Experimental neutrino physics in a nuclear landscape

    Full text link
    There are profound connections between neutrino physics and nuclear experiments. Exceptionally precise measurements of single and double beta-decay spectra illuminate the scale and nature of neutrino mass and may finally answer the question of whether neutrinos are their own antimatter counterparts. Neutrino-nucleus scattering underpins oscillation experiments and probes nuclear structure, neutrinos offer a rare vantage point into collapsing stars and nuclear fission reactors, and techniques pioneered in neutrino nuclear-physics experiments are advancing quantum-sensing technologies. In this article, we review current and planned efforts at the intersection of neutrino and nuclear experiments.Comment: 22 pages, 4 figures, 1 table.

    A high-finesse Fabry-Perot cavity with a frequency-doubled green laser for precision Compton polarimetry at Jefferson Lab

    Full text link
    A high-finesse Fabry-Perot cavity with a frequency-doubled continuous wave green laser (532~nm) has been built and installed in Hall A of Jefferson Lab for high precision Compton polarimetry. The infrared (1064~nm) beam from a ytterbium-doped fiber amplifier seeded by a Nd:YAG nonplanar ring oscillator laser is frequency doubled in a single-pass periodically poled MgO:LiNbO3_{3} crystal. The maximum achieved green power at 5 W IR pump power is 1.74 W with a total conversion efficiency of 34.8\%. The green beam is injected into the optical resonant cavity and enhanced up to 3.7~kW with a corresponding enhancement of 3800. The polarization transfer function has been measured in order to determine the intra-cavity circular laser polarization within a measurement uncertainty of 0.7\%. The PREx experiment at Jefferson Lab used this system for the first time and achieved 1.0\% precision in polarization measurements of an electron beam with energy and current of 1.0~GeV and 50~μ\muA.Comment: 20 pages, 22 figures, revised version of arXiv:1601.00251v1, submitted to NIM

    Improving creative thinking skill of fluid dynamic through IBL_STEM with formative assessment

    The concept of Dynamic Fluid is part of the Fluid Mechanics that underlies several phenomena and technologies in everyday life. Improving students' ability to think creatively is needed to prepare students for the challenges of the 21st Century. However, students' creative thinking skill are still low on dynamic fluid material, and the application of integrated STEM Inquiry with Formative Assessment (IBL-STEM with FA) solutions is still rare. This study aims to improve students' creative thinking skill and describe the difficulties of creative thinking on Dynamic Fluid material after IBL-STEM with FA. The mixed methods with an embedded experimental design used the research subjects of 34 students (M = 14 and F = 20) in class XI of state senior high schools in Jombang, Indonesia, selected by purposive sampling. This study used the Fluid Dynamics Creative Thinking Skill Test instrument in the form of 6 essay questions with a reliability of 0.869. The pretest and posttest quantitative data were analyzed by the Wilcoxon test, d effect, and N- gain. Whereas qualitative data on the variety of students' answers, and the results of interviews and observations were analyzed by coding, data reduction, and conclusion gathering. Variety of student answers was coded based on not creative, less creative, quite creative, creative, and very creative. The results showed that intervention significantly increased students' ability to think creatively with N-gain = 0.64 (medium category) and d-effect size = 5.05 (very large category). After learning, students were still experiencing difficulties to think flexibly both (1) developing tools based on continuity concept and (2) developing an effective and environmentally friendly chimney design. Also, students still have difficulty in original thinking to get high speed and widespread sprayers. Nevertheless, an increase in students' creative thinking on dynamic fluid material indicates that IBL-STEM with FA can be applied in learning
