Abstract(in English) | A key distribution scheme (KDS) is a method of distributing secret keys in the network. In the conventional KDS, the security model was defined for collision attack by using the available information of centers and users. In this study, we define a KDS based on a new security model considering leakage of secret information of key distribution centers as well as collusion of centers and users. In our definition of KDS, we derive lower bounds on memory sizes and amount of received information of each entity, and show the concrete construction that meets corresponding lower bounds. |
