Paper 2023/625 Efficient Information-Theoretic Distributed Point Function with General Output Groups , ShanghaiTech University , ShanghaiTech University , ShanghaiTech University Abstract An $n$-server information-theoretic \textit{Distributed Point Function} (DPF) allows a client to secret-share a point function $f_{\alpha,\beta}(x)$ with domain $[N]$ and output group $\mathbb{G}$ among $n$ servers such that each server learns no information about the function from its share (called a key)...
