PFSS 1.0.0
PFSS is a library for function secret sharing (FSS) developed by Stealth Software Technologies, Inc. (Stealth). Our library provides APIs for performing an efficient two-way sharing of point functions based on the work from Gilboa-Ishai (EUROCRYPT 2014) and Boyle-Gilboa-Ishai (EUROCRYPT 2015) with optimizations from the Boyle-Gilboa-Ishai (CCS 2016) result. We also provide batched APIs to reduce overhead, which is useful for applications that use FSS for large-scale computations, such as our recent work of applying FSS to various flavors of Private Set Intersection. For the latter work, we provide a reference to Dittmer et al. on arXiv and IACR ePrint.
