Abstract

Security is one of the major concerns for using multicast communications in many Internet applications. This paper identifies and discusses various issues related to secure multicasting. It reviews some requirements for creating secure multicast sessions and gives an overview of existing secure multicast schemes. The main security problem discussed is key management. Taxonomy of various schemes that provide solutions to this problem is given and new improved key distribution schemes are provided. We expand the traditional two basic schemes, the single-group and singletree, into three new schemes: group-of-trees, tree-of-groups and tree-oftrees. The performance of all these schemes is evaluated as a function of the multicast group size.
