WebApr 8, 2024 · PSI was first proposed by Freedman et al. , who transformed the element comparison problem into the polynomial root problem and realized PSI through multiplicative homomorphic encryption. However, when the polynomial order is large, it will lead to a costly exponential computation of the homomorphic encryption.
