A Note on ``Privacy Preserving n-Party Scalar Product Protocol''

Lihua Liu, Shanghai Maritime University
Abstract

We show that the scalar product protocol [IEEE Trans. Parallel Distrib. Syst. 2023, 1060-1066] is insecure against semi-honest server attack, not as claimed. Besides, its complexity increases exponentially with the number $n$, which cannot be put into practice.
