Abstract
Secure scalar product protocol has wide applications for privacy-preservation in collaborative computation. In this paper, we propose a new secure scalar product protocol, which does not employ any public-key encryption and third party. Compared to scalar product computation without privacy-preservation, our proposed scheme introduces no extra communication overheads and little extra computation cost. That is, the new scheme can achieve almost optimal running efficiency, and thus is much applicable to privacy-preservation for large-scale data in collaborative computation. Theoretical analysis and evaluation indicate the security and efficiency of our scheme.
