Fairy ring: Ubiquitous secure multiparty computation framework for smartphone applications

Tadanori Teruya, Yoshiki Aoki, Jun Sakuma

Abstract: In this paper, we present a framework for secure multiparty computation on smartphones. Our framework provides protocols, which are constructed by additively homo-morphic encryption, to guarantee security against semi-honest adversaries without collusion. The protocols made using our framework follow a client-server model, thus users of our framework can easily and jointly execute these protocols as a service by accessing a server using their smartphones. Our framework provides four primitive protocols, and application protocols are constructed by using these primitive protocols. Consequently, our framework provides an environment that allows non-experts to easily use and develop smartphone applications of secure multiparty computation. To demonstrate the practicability of our framework, we implement and execute voting on 16 smartphones.
