Abstract

Multicast has potential to make delivery of large files and streams over the Internet very efficient. However, strong source authentication for multicast is needed to make delivery of important data possible. Information such as stock quotes is valuable only if the data can be trusted. In this paper, we present an architecture which allows wireless mobile devices with limited computational abilities to receive source authenticated multicast over an unreliable wireless access network.
