AuthoCast—a mobility-compliant protocol framework for multicast sender authentication
TL;DR: A solution to the mobile source authentication problem is presented that complies to IPv6 mobility signaling standards and a common design is derived to jointly comply with the mobile any source and source specic multicast protocols that are currently proposed.

Abstract: Summary Mobility is considered a key technology of the next generation Internet and has been standardized within the IETF. Rapidly emerging multimedia group applications such as IPTV, MMORPGs and video conferencing increase the demand for mobile group communication, but a standard design of mobile multicast is still awaited. The open problem poses signicant operational and security challenges to the Internet infrastructure. This paper introduces a protocol framework for authenticating multicast sources and securing their mobility handovers. Its contribution is twofold: At rst, the current mobile multicast problem and solution spaces are summarized from the security perspective. At second, a solution to the mobile source authentication problem is presented that complies to IPv6 mobility signaling standards. Using an autonomously veriable one-way authentication based on cryptographically generated addresses, a common design is derived to jointly comply with the mobile any source and source specic multicast protocols that are currently proposed. This light-weight scheme smoothly extends the unicast enhanced route optimization for mobile IPv6 and adds only little overhead to multicast packets and protocol operations.

Fast adaptive routing supporting mobile senders in Source Specific Multicast
TL;DR: The Enhanced Tree Morphing (ETM) protocol is proposed, which dynamically adapts SSM forwarding states to sender mobility, and transforms (morphs) source specific distribution trees into new, optimal trees rooted at a relocated source.

TL;DR: It is shown, how the use of cryptographically generated identifiers enables the application to authenticate data on a packet level, thereby preventing abuse and impersonation of the conference overlay network.
Distributed SIP conference management with autonomously authenticated sources and its application to an H.264 videoconferencing software for mobiles
TL;DR: This work is dedicated to the development of a software-based H.264 video codec implementation and the specific aspects resulting from tuning such a highly resource-intensive software codec to the given target platform of a standard consumer smartphone.
Why We Shouldn't Forget Multicast in Name-oriented Publish/Subscribe
TL;DR: It is argued that an inclusion of multicast will grant additional benefits to the network layer, namely efficient distribution of real-time data, a many-to-many communication model, and simplified rendezvous processes.
