This lack of security support has been a major hurdle for auditing documents, claiming data possession, and proof of authorship. In this paper, we present a novel idea for secure accountability of timing(More)
A 9.0-GHz dielectric resonator oscillator (DRO), generating a CW output power of 2.5 W at room temperature, has been designed and fabricated using a high-power GaAs MESFET and a dielectric resonator (DR) in a parallel feedback configuration. The oscillator exhibited a frequency stability of better than 130 ppm, without any temperature compensation, over the(More)
