| Abstract(in English) | It is known that tree structures are useful in the key management schemes, which realize secure multicast communications encrypted by group keys on a public network. Selcku and Sidhu have proposed an efficient scheme by introducing the probabilities that members will leave a goup. In this report, the asymptotic tight bound of the key update cost is derived for Selcuk-Sidhu scheme. Furthermore, a new key management scheme is proposed and analyzed, which takes account of key update costs of joining addition to leaving. |
