Abstract

AbstractSo far our focus was on general n-party secure MPC, where the emphasis was on asymptotic efficiency. In this chapter, we discuss a special case of perfectly-secure MPC, namely MPC for small number of parties. Instead of asymptotic efficiency, our focus will be on concrete efficiency. The use case considered in this chapter is that of secure 3-party computation (secure 3PC), with one passive corruption. We discuss two different protocols in this setting, the first one due to [9] and the second one due to [47].
