Abstract:
Distributed group communication is the most optimistic approach to provide
a secure group communication in many emerging network applications such as peer to
peer communication, Skype, Facebook, Whatsapp, PAY-TV, Video conferencing, Email,
Twitter and online network games. Because, in distributed group communication
the data are sent from any one of the group members to the remaining group members
and also there is no centralized coordinator in the distributed group communication and
hence it would take more computational complexity. Moreover, in distributed group
communication, the users themselves generate and distribute the necessary keys to
maintain the secrecy and group membership. Hence, providing security with less
computation complexity is a challenging task in distributed group communication. In
this paper, a detailed survey has been done towards various distributed group
communication and also comparative performance analysis has been done for all the
approaches. In order to do that, we have considered various parameters such as
computation complexity, communication complexity and storage complexity of both the
user and the server during key generation, key distribution and key updation process.
Moreover, in this paper we have also included various security challenges that need to
be solved to make the distributed group communication more secure. Finally, we have
also given a solution to improve the various parameters in order to increase the security
and performance of the distributed communication performed in various applications.
