Title:
Secure Computation for G-Module and its Applications
Authors: Qizhi Zhang, Bingsheng Zhang, Lichun Li, Shan Yin, Juanjuan Sun
Abstract:Secure computation enables two or more parties to jointly evaluate a function without revealing to each other their private input. G-module is an abelian group M, where the group G acts compatibly with the abelian group structure on M. In this work, we present several secure computation protocols for G-module operations in the online/offline mode. We then show how to instantiate those protocols to implement many widely used secure computation primitives in privacy-preserving machine learning and data mining, such as oblivious cyclic shift, one-round shared OT, oblivious permutation, oblivious shuffle, secure comparison, oblivious selection, DReLU, and ReLU, etc. All the proposed protocols are constant-round, and they are 2X - 10X more efficient than the-state-of-the-art constant-round protocols in terms of communication complexity.
