This is a follow-up to a Stackoverflow question about shuffling an array randomly. There are established algorithms (such as the Knuth-Fisher-Yates Shuffle) that one should use to shuffle an array, rather than relying on "naive" ad-hoc implementations. I am now interested in proving (or disproving) that my naive algorithm is broken (as in ...
WebApr 11, 2024 · This work introduces variation-ratio reduction as a unified framework for privacy amplification analyses in the shuffle model and shows that the framework yields tighter bounds for both single-message and multi-message encoders and results in stricter privacy accounting for common sampling-based local randomizers.
