Memory-less discrete gaussian sampler on fpga
Web4 sep. 2015 · We speed up the sampler by using a small lookup table, and the hit rate of the lookup table is as high as 94%. With these optimizations, our sampler takes on average 9.44 random bits and 2.28 clock cycles to generate a sample. It consumes 1 block RAM and 17 slices on a Spartan-6 FPGA. Webcrete (e.g., population counts), adding continuous noise makes the result less interpretable. With these shortcomings in mind, we introduce and analyze the discrete Gaussian in the context of differential privacy. Specifically, we theoretically and experimentally show that adding discrete Gaussian noise provides essentially the same privacy and
