As a major breakthrough, in 2009 Gentry introduced the first plausible construction of a fully homomorphic encryption (FHE) scheme. FHE allows the evaluation of arbitrary functions directly on encrypted data on untwisted servers. In 2010, Gentry and Halevi presented the first FHE implementation on an IBM x3500 server. However, this implementation remains(More)
—In 2010 Gentry and Halevi presented the first FHE implementation. FHE allows the evaluation of arbitrary functions directly on encrypted data on untrusted servers. However, even for the small setting with 2,048 dimensions, the authors reported a performance of 1.8 seconds for a single bit encryption and 32 seconds for recryption on a high end server. Much(More)
This paper presents the design of a powerand areaefficient high-speed 768 000-bit multiplier, based on fast Fourier transform multiplication for fully homomorphic encryption operations. A memory-based in-place architecture is presented for the FFT processor that performs 64 000-point finite-field FFT operations using a radix-16 computing unit and 16(More)
Multipath is undesirable for Global Navigation Satellite System (GNSS) receivers, since the reception of multipath can create a significant distortion to the shape of the correlation function leading to an error in the receiv-ers' position estimate. Many multipath mitigation techniques exist in the literature to deal with the multipath propagation problem(More)
