| Abstract(in English) | We have proposed some methods for masked sharing of group keys (MaSK), in which an entity called "coordinator" can share a group key with all other entities except one or more specific one called "masked entity(ies)". A primitive method is that the coordinator delivers the group key to all entities individually except the masked entity(ies). On contrary, our methods are useful on a large group because the amount of transmission and the delay time do not rely on the size of group. In this paper, we will propose the speeding up technique for MaSK3 in SCIS'99. Moreover we will compare MaSK with the primitive methods by using DES and RSA. |
