安全内积,即计算所有项都是加密形式的内积,是各种隐私保护应用的核心技术。在本文中,我们提出了一个通用而有效的方法来计算安全的内积向量(或矩阵)使用矩阵迹的性质。事实上,我们的方法不仅适用于基于LWE和基于环LWE的同态加密方案,而且比以前已知的方法更有效。
Secure inner product, namely the computation of inner product whose terms are all in encrypted form, is the central technique for various privacy-preserving applications. In this paper, we propose a generic yet efficient method to compute secure inner products of vectors (or matrices) using matrix trace properties. Indeed, our method not only applies to both LWE-based and ring-LWE-based homomorphic encryption schemes, but also is more efficient compared to previously known methods.
