  • Robust Target Tracking with Unreliable Binary Proximity Sensors
    2006 IEEE International Conference on Acoustics Speech and Signal Processing Proceedings, 2006
    Co-Authors: B.f. La Scala, C.o. Savage
    Abstract:

    This paper describes an algorithm for target tracking in a distributed network of Binary proximity sensors that is robust to sensor failures. Tracking with such sensors is a difficult problem as they only transmit a single Binary Digit regarding the presence of a target. The operational status of these sensors may also not be accurately known. This paper describes a Gaussian mixture-based tracking algorithm that addresses these two issues

  • Scheduling Binary Proximity Sensors for Robust Target Tracking
    2006 9th International Conference on Information Fusion, 2006
    Co-Authors: B.f. La Scala
    Abstract:

    This paper describes two scheduling algorithms designed to improve target tracking performance in a distributed network of Binary proximity sensors. Tracking with such sensors is a difficult problem as they only transmit a single Binary Digit regarding the presence of a target. In addition, the operational status of these sensors may not be accurately known. This paper describes extensions to a Gaussian mixture-based tracking algorithm which aid in addressing these problems. These extensions reduce computational complexity and improve accuracy by scheduling status queries to selected sensors

  • Signed Binary Digit Representation to Simplify 3D-EZW
    2007 IEEE International Conference on Acoustics Speech and Signal Processing - ICASSP '07, 2007
    Co-Authors: Emmanuel Christophe, Pierre Duhamel, Corinne Mailhes
    Abstract:

    Zerotree based coders have shown a good ability to be successfully adapted to 3D image coding. This paper focuses on the adaptation of EZW for the compression of hyperspectral images with reduced complexity. The subordinate pass is removed so that the location of significant coefficients does not need to be kept in memory. To compensate the quality loss due to this removal, a signed Binary Digit representation is used to increase the efficiency of zerotrees. Contextual arithmetic coding with very limited contexts is also used. Finally, we show that this simplified version of 3D-EZW performs almost as well as the original one.

  • adaptation of zerotrees using signed Binary Digit representations for 3d image coding
    Eurasip Journal on Image and Video Processing, 2007
    Co-Authors: Emmanuel Christophe, Pierre Duhamel, Corinne Mailhes
    Abstract:

    Zerotrees of wavelet coefficients have shown a good adaptability for the compression of three-dimensional images. EZW, the original algorithm using zerotree, shows good performance and was successfully adapted to 3D image compression. This paper focuses on the adaptation of EZW for the compression of hyperspectral images. The subordinate pass is suppressed to remove the necessity to keep the significant pixels in memory. To compensate the loss due to this removal, signed Binary Digit representations are used to increase the efficiency of zerotrees. Contextual arithmetic coding with very limited contexts is also used. Finally, we show that this simplified version of 3D-EZW performs almost as well as the original one.

  • Experimental validation of a novel chaotic circuit for true random Binary Digit generation in cryptographic module application
    2009 Ph.D. Research in Microelectronics and Electronics, 2009
    Co-Authors: Maria Blaszczyk, R. Guinee
    Abstract:

    In this paper the experimental validation of a novel, modified double scroll chaotic attractor circuit, employed as a true random Binary generator (TRBG) is presented. The double scroll attractor is modeled on a chaotic circuit for nonlinear operation leading to stochastic like behavior. The output from the chaotic circuit which is a correlated Binary sequence is scrambled with a pseudo random Binary sequence generator (PRBSG) topology to yield a true random Binary source for key stream generation. The modified chaotic circuit has been first modeled in PSpice software and its state space formulation was implemented in Matlab and Simulink software to gauge simulation accuracy and potential as a cryptographic module via statistical testing. The randomness attributes of the modified generator, obtained from both the PSpice state space model along with the hardware implementation, using the PRBSG de-correlator were successfully tested by the well known NIST Test Suite and Diehard Test Set for statistical validation. A physical TRBG has been constructed on the basis of the proposed PRBSG modification with all statistical tests successfully passed confirming theoretical expectations.

    Abstract:

    In this paper the experimental validation of a novel, modified double scroll chaotic attractor circuit, employed as a true random Binary generator (TRBG) is presented. The double scroll attractor is modeled on Chua's circuit constituted as independent chaotic oscillator using passive only nonlinear device for nonlinear operation leading to chaotic behavior. The output from the chaotic circuit which is a correlated Binary sequence is scrambled with a pseudo random Binary sequence generator (PRBSG) topology to yield a true random Binary source for key stream generation. The modified chaotic circuit has been first modeled in PSpice software. The randomness attributes of the modified generator, obtained from both the PSpice model and hardware implementation, using the PRBSG de-correlator were successfully tested by the well known NIST Test Suite and Diehard Test Set for statistical validation. Output Binary streams from the proposed modified generator were examined for randomness using both Test Suites with all tests successfully passed for both PSpice model and experimental chaotic circuit generator.

  • Experimental validation of the hardware implementation of a novel true random Binary sequence generator for keystream applications
    MILCOM 2009 - 2009 IEEE Military Communications Conference, 2009
    Co-Authors: R. Guinee, Maria Blaszczyk
    Abstract:

    In this paper the experimental validation of a novel, modified double scroll chaotic attractor circuit, employed as a true random Binary generator (TRBG) for cryptographic applications is presented. The double scroll attractor is modeled on Chua's circuit for nonlinear operation leading to chaotic behavior. The output from the chaotic circuit which is a partially correlated Binary sequence is scrambled with a cascaded series of lengthened pseudo random Binary sequence generators (PRBSG) to eliminate Binary Digit inter dependency for decorrelation purposes. This approach results in a successful modified generator as a true random Binary source for key stream generation. The modified chaotic circuit was first modeled in PSpice software to gauge its potential as an AES cryptographic module via statistical testing. The stochastic attributes of the modified generator, obtained through PSpice modelling and simulation and its post hardware implementation, using the PRBSG de-correlator were successfully tested by the well known NIST and Diehard Test Suites for statistical validation. A physical TRBG has been constructed on the basis of the proposed PRBSG modification with all statistical tests successfully passed confirming theoretical expectations which admits to its adequacy for deployment an AES module.

  • Hardware implementation on PCB in tandem with FPGA and experimental validation of a novel true random Binary generator
    2009 IEEE International SOC Conference (SOCC), 2009
    Co-Authors: Maria Blaszczyk, R. Guinee
    Abstract:

    In this paper the experimental validation along with mixed system integration of a novel, modified double scroll chaotic attractor circuit, employed as a true random Binary generator (TRBG) is presented. The double scroll attractor is modeled on Chua's circuit for nonlinear operation leading to double scroll chaotic behavior. The output from the chaotic circuit which is a correlated Binary sequence is scrambled with a pseudo random Binary sequence generator (PRBSG) topology to yield a true random Binary source for key stream generation. The modified chaotic circuit has been implemented on printed circuit board (PCB) along with a field programmable gate array (FPGA) for true random bits generation. The randomness attributes of the hardware generator construction, using the PRBSG de-correlator were successfully tested by the well known NIST Test Suite and Diehard Test set for statistical validation. Output Binary streams from the proposed modified generator were examined for randomness using both Test Suites with all tests successfully passed for both experimental chaotic circuit and PSpice simulation model which was used as a yardstick for statistical attributes. The hardware implementation of proposed TRBG has been constructed as a combination of chaotic generator analog circuitry on PCB and PRBSG Digital operation leading to Binary Digit generation in FPGA. This TRSG system could be easily implemented as a complete hardware integrated cryptographic module for usage in mobile communication platform applications. A physical TRBG has been constructed on the basis of the proposed PRBSG modification with all statistical tests successfully passed.
