Analog Privacy-Preserving Coded Computing


In privacy-preserving coded computing, a main nodes offloads computations to a set of worker nodes without leaking information about the it's private data (unless too many workers collude).

Many approaches in the literature consider computations over finite fields. However, in many applications in practice, e.g. machine learning, computations over (approximations of) the reals are required.

The goal of this seminar work is to review the recent approaches from the literature on privacy-preserving coded computing over analog domains and highlight their benefits and drawbacks.
