Efficient Non-Repudiation Multicast Source Authentication Schemes

摘要

In secure multicast communication, packet source authentication is a bottleneck problem due to the dynamic property of the multicast group, unreliability of data transmission and the large number of data packets. This paper proposes a novel authentication scheme called B-MSAS (Balance Multicast Source Authentication Scheme) that can be used to solve this problem, in which a new message authentication technique is introduced. This scheme dramatically reduces the signature size overhead and raises the signature rate. It provides the non-repudiation service, high loss resistance, and can easily be scaled up to potentially millions of receivers, and hence has a sweeping applicability. It should have applications to many practical problems.
