| Abstract(in English) | Multi-party computation is a protocol that allows participants to communicate each other and know only the result of a certain evaluation function while hiding their own input information. In addition, non-interactive multi-party computation is the simple communication protocol in which participants do not communicate each other. However, when considering applying a non-interactive model to cloud services and applications, whose demand is increasing recent years, there is a problem that the protocol must be re-executed as the number of participants increases. In this paper, we build a model of non-interactive multi-party computation even if the number of participants changes dynamically. And, we propose an efficient construction with low communication complexity for non-interactive multi-party computation having a symmetric function. |
