  • Random number generation on handheld devices for cryptographic applications

    Creator:
    Montville, Adam W.
    Abstract:
    Random number generation is important in many fields today. It is particularly important in the field of cryptography when generating nonce values, cryptographic keys, and other data required in many cryptographic applications. The proliferation of small, handheld devices that are typically connected to large networks via a wireless connection requires...

  • High-speed algorithms & architectures for number-theoretic cryptosystems

    Creator:
    Acar, Tolga
    Abstract:
    Computer and network security systems rely on the privacy and authenticity of information, which requires implementation of cryptographic functions. Software implementations of these functions are often desired because of their flexibility and cost effectiveness. In this study, we concentrate on developing high-speed and area-efficient modular multiplication and exponentiation algorithms for...

  • General pole number model for the brushless doubly-fed machine

    Creator:
    Boger, Michael S.
    Abstract:
    The Brush less Doubly-Fed Machine (BDFM) has the potential to be a more cost effective replacement for conventional induction or synchronous machine drives. The BDFM has two stator windings: a power winding and a control winding. An electronic power converter of variable voltage and frequency is connected to the control...

  • Performance and optimization of pulsed UWB localization with large number of sources

    Creator:
    Kwon, Changho
    Abstract:
    Pulsed ultra-wideband (UWB) radio uses extremely short pulses to transmit information. Such pulses provide very fine timing information, which has led to technological advances in high-precision localization. This thesis focuses on techniques and experiments of Time-Difference-of-Arrival (TDOA) localization of a large number of simultaneous sources. First, common localization techniques such...

  • Throughput optimization for single-hop wireless networks using network coding

    Creator:
    Tran, Tuan Tho
    Abstract:
    Recent advances in wireless technologies have helped the proliferation of wireless devices, ranging from hand-held devices such as cellular phones to more powerful mobile computing platforms as such laptops [1]. Along with that, the end users’ applications running on these devices, ranging from text message to multimedia applications such as...

  • Directional 60 GHz communication networks

    Creator:
    Yildirim, Ferhat (Ahmet Ferhat)
    Abstract:
    It is well known that multipath effects cause inter-symbol interference (ISI) for high-speed signaling and ultimately limit the achievable data rate at any frequency band. In this thesis, we study several different methods to tackle this issue and provide solutions for establishing efficient wireless links that can provide several Gbps...

  • Fast software implementations of block ciphers

    Creator:
    Sessions, Julian Brently
    Abstract:
    Three block ciphers are considered to determine how well they can be implemented on existing superscalar architectures such as the Intel Pentium. An examination of the Pentium architecture suggests that substantial performance increases can be achieved if particular rules are followed. Software libraries are written in high-level C language and...

  • Preliminary studies on a magnetic elevator for solids (MES)

    Creator:
    Ranawake, Udaya A.
    Abstract:
    The thesis describes the preliminary studies on a laboratory model of a magnetic elevator intended as part of a system for circulating magnetic materials in chemical reactors. A multiple coil laboratory model, controlled by computer, was designed and constructed. Current measuring transducers were used to monitor system performance and study...

  • A computer simulation model of land use dynamics in the State of Oregon

    Creator:
    Calligan, C. C.
    Abstract:
    The dynamics of land use in the State of Oregon are simulated on a digital computer. The introductory chapter outlines the complex nature of the problems facing the post-industrial society and argues that the scientific and professional estates share in the responsibility for public policy formulation. The second chapter .presents...

  • Digital clocks based upon dual side band suppressed carrier modulation

    Creator:
    Arnett, David W.
    Abstract:
    A method and apparatus are presented for generating suppressed carrier digital clock signals. These clock signals have the advantage of being broad band in nature and thus exhibiting lower power spectral density. Structures or systems utilizing such clock signals would be less likely to create electromagnetic noise of sufficient intensity...
