A Distributed Model for Secure and Scalable Group Communication
H Kim, SM Hong, Hyunsoo Yoon · KAIST Institutional Repository (KAIST) · 2005
Secure group communication enables only the users in that group securely communicate with each other.Because the users can join or leave the group dynamically, scalability is a major concern.In this paper we propose a scalable distributed model using multiplicative one-way functions.When totally users are in the group, proposed model reduces the size of multicast message required in join or leave operation from to keeping other costs comparable.Therefore, proposed model is very applicable to a wide area network environment or a low-bandwidth channel such as ad hoc network.
