Abstract: A High Assurance Configuration Security Processor (HACSP) for a computing device may perform real-time integrity measurements of an actual bitstream run-time performance against what is expected. The HACSP may be self-contained and have a relatively small footprint. The HACSP may be vendor-agnostic, and may be a trusted system application for the computing device. The HACSP may ensure the security of user application bitstream load and update during device configuration, and may implement security mechanisms for independent secure trusted attestation and integrity measurement mechanisms to report and provide reliable evidence about the “trustworthiness” of the system during user bitstream execution.

Abstract: An apparatus is configured to receive and demodulate a homodyne carrier signal, where the homodyne carrier signal comprises sensor data of at least two sensors. A method includes receiving sensed signals from at least two sensors; and modulating the sensed signals on a single homodyne carrier signal. A demodulator is configured to receive and demodulate a homodyne carrier signal carrying sensor data of at least two sensors.

Abstract: An apparatus in one example configured to receive and demodulate a homodyne carrier signal, where the homodyne carrier signal comprises sensor data for at least two sensors.

Abstract: A Fourier transform is applied (205) to a received multiple-carrier phase-modulated signal. The output of the transform includes real and imaginary elements that are associated with the multiple carriers. These elements are processed to provide a magnitude (209) and a sign (211) for the quadrature, Q, and in-phase, I, components of the desired signal. Q and I are processed (213) to yield the desired output signal that approximates the originally obtained signals that were phase-modulated and transmitted on the multiple carriers.
