Abstract
To renew the group key securing on the mobile communication needs that it can be not oかy re-shared by all members of the group with the exception of members excluded but also prevented from making a fraudulent use of a terminal's registered key because of a leakage of information from the loss of terminal. In this paper, we propose an efficient renewal mechanism of group key in order for all members of the group to be able to get digital information and to perform the renewal of group key in a small-scale conference employing the Fiat-Shamir method. It can guarantee the security of terminals, since a terminal generates security information needed for key renewal, and then renews the group key for mutual communication.
