Abstract

We propose a new framework for key management toconstruct a secure multicasting environment.When rekey-ing, only one message needs to be generated, and the mes-sage size is a constant.Especially when the group size islarge, our framework largely reduces the traffic in the net-work.In this paper, two solutions are given to carry outthis framework, which are closed curve solution (CCS)andperpendicular space solution (PSS),respectively.One isbased on geometric approach and the other on linear alge-braic approach.Our framework is also compatible to othergroup communication protocols.
