Abstract: An overlook the heterogeneity of receivers by letting the sender choose the block size, divide a multicast stream into blocks, associate each block with a signature and spread the effect of the signature across, all the packets in the block through hash graphs or coding algorithms. The correlation among packets makes them vulnerable to packet loss which is inherent in the internet and wireless networks. Moreover, the lack of Denial of Service (DoS) resilience renders most of them vulnerable to packet injection in hostile environments. In this study, researchers propose a novel multicast authentication protocol, namely MABS, including two schemes. The basic scheme (MABS-B) eliminates the correlation among packets and thus, provides the perfect resilience to packet loss and it is also efficient in terms of latency, computation and communication overhead due to an efficient cryptographic primitive called batch signature which supports the authentication of any number of packets simultaneously. Researchers, also present an enhanced scheme MABS-E which combines the basic scheme with a packet filtering mechanism to alleviate the DoS impact while preserving the perfect resilience to packet loss.
