....there is no standard way to provide the keys needed to decrypt and authenticate packets to the authorised members of a multicast group. A number of proposals have been made, such as using secure point to point connections between a multicast group member and group controller to distribute keys [Canetti99], but are currently far from implementation. Controllers can assign unique Security Parameters Index values for a group to avoid collisions on values chosen by receivers as is standard with unicast IPSEC. If individual authentication or replay protection is required, the controller can also assign ....

....3: Subscription optimization 4 Security Manycasting has a potential of resolving many critical security issues that take place with the existing versions of multicast protocol. Presently, there has already been a signi cant amount of work done in the area of secure multicast communications [7]. Therefore, instead of replacing the work that has already been done, we will make use of it as one of manycasting extensions. Consequently, as new kinds of security threats are discovered, additional extensions will be added to address these new security threats and protect end clients. One of ....

....while maintaining independence from the underlying multicast routing. Sub group multicast into areas by an AKD is achieved using administratively scoped multicast [22, 23] Other efforts focusing on key dissemination includes the centralized architecture and im14 plementation reported in [24], and a recent group security association agreement protocol (related to key management) in [25] ffl Key relationships: Approaches to provide scalable solutions for key management have also been taken from the perspective of building in features into keys, such that managing the keys used for ....

.... p n) a value noted in [1] Key Words: Multicast Security, Key Distribution, Trees, Convex Optimization 1 Introduction In order to reduce the sender and the network resources, secure multicast encryption requires all the group members to share a single data encryption key called the group key [2, 1, 18, 12, 13, 17, 11]. In order to protect the access to group communication, the group key needs to be updated whenever a member leaves or joins the group. Most of the recent literature assumes that there is a single group controller that is responsible for key distribution [2, 1, 3] We make the same assumption in ....
