| Outline of Final Research Achievements |
Conventional cake-cutting protocols require that all players must execute a protocol at the same time. This work eliminates this restriction. In the proposed protocol, all player can join to and leave from the cake-cutting procedure at his/her convenience. How to cut the cake to maximize each player's utility by this setting is shown.
Security is another important issue to realize fair cake-cutting. If a player's preference to the cake is known to another player, the player can cut the cake falsely and obtain more utility. In order to prevent this flaw, we show a secure cake-cutting protocol using a secure auction protocol.
