| Abstract(in English) | In this paper, we propose an efficient N-party password-authenticated key exchange (so-called N-PAKE) protocol after showing the intermediate step. For that, we propose another 3-party PAKE protocol that is a basis of the N-PAKE protocol. The N-PAKE protocol is remarkably efficient rather than the previous works and a per-client computational cost is independent on the group size. Specifically, each client involved in the protocol is required only four exponentiations and some negligible operations. |
